Being location independent-traveling or living as a digital nomad-increases your risk for data loss.

Your laptop could be stolen from your Airbnb rental, or snatched away with your backpack tomorrow.

The extra wear and tear on your gadgets will shorten their lifespan. Such as exposure to high heat, humidity, unexpected rain, or even sand on a beach.

And the lack of reliable internet on that tropical island you are staying on will lead you to not even bother with Dropbox or some other cloud based backup service.

So do you have all of your photos on your laptop, and now else?

If you are using an external drive; when that drive dies, will 6 months worth of your work die with it?

When the internet is slow to the point that you can not rely on Dropbox, Google Docs, or some other cloud backup service to work for several days in a row; are your most recent computer files still being protected?

Because if you do not have a good answer for those questions above, well then, continue reading. As this article will help you to sort out a bulletproof solution for keeping your data protected while traveling or living anywhere in the world.

The Rule of 3

In the world of rock climbing, there exist what is called a climbing anchor. It is what prevails you from plummeting to the ground if you were to take a fall during an attempt to ascend a towering rock face.

Since it's the difference between being alive or dead if your anchor fails, it is not composed of just a single point of protection. There are at least 3 solid protection points within a proper climbing anchor.

The Rule of 3 being used in rock climbing

This changes the risk of a complete anchor failure into something very improbable. Even if a piece of gear were to snap or if part of the anchor were to dislodge with a loose rock; you'll still be alive.

A similar principle should be applied to how you protect your data. This is the Backup Rule of 3, also known as the “Backup 3-2-1 rule”.

  • 3 copies of your data. Because two copies is not enough if your data is important to you.
  • 2 different media formats for your backup . Such as external hard drive + SD card.
  • 1 off-site backup. If your bamboo bungalow goes down in flames along with all of your possessions within it, how will you get your photos back?

Why is this necessary?

As with climbing, things can and will go wrong.

A rogue wave at the beach could knock you over into the water along with your laptop and external drive.

That budget airline you flew with could lose all of your luggage.

And an online backup of your data can become corrupt and useless.

A real-life solution

Adhering to the 3-2-1 Backup principle with your critical and most important data is not as difficult or technical as it may sound.

Step 1

Pickup an external hard drive if you do not have one already. Choose a drive with at least double the capacity of what you're currently using. So if 400 gigs of your laptop storage is being used, buy a 1 terabyte drive.

If you are unsure about what hard drive to buy, a Western Digital My Passport Ultra is a great option. It is small, fast, reliable, and reliably inexpensively. It also includes easy-to-use backup software for Windows.

After plugging in your drive you'll want to start backing up your laptop right away.

You can do this on a Mac in less than a minute by enabling Time Machine.

If you have a PC, use the backup software included with your external drive. If your drive does not have any backup software that comes with it, one software solution that is trusted by many is Genie Timeline.

Step 2

Now you will want to start pushing your most important files into the cloud.

For a simple all-in-one cloud backup solution, Dropbox is highly recommended. If you prefer Google Drive or some other service, stick with them, as this advice can easily be adapted to those alternatives.

For $ 8.25 a month ($ 99 yearly fee), you can get 1 terabyte of space with Dropbox at this time of writing.

Place all of your most important files in your Dropbox folder. If you are using a mac, here is an article that explains how to brilliantly do so with an app called MacDropAny. But do not worry, you can do the same with a PC .

At this point you will have 3 copies of your most important files. They are on your laptop, external drive, and within Dropbox. You are using two different types of media for backing up; your external drive and your “cloud drive”, which is Dropbox or a similar service. And you are using an off-site backup, with this again being Dropbox.

And then there is Step 3

As a digital nomad, you will need to go one step further to fully follow our Rule of 3. This is because the internet is often times unreliable as we change between countries, locations, or when we go off traveling.

And there is one simple remedy for this.

Grab a high-capacity USB thumb drive. The 128GB SanDisk Cruzer is a solid choice, and can be found on Amazon for under $ 30 dollars.

Stash it separately from where you keep your laptop and external drive whenever possible.

When the internet is too slow for syncing with Dropbox for a day or longer, you'll want to copy your most recent file changes to your USB stick at the end of the day.

It's a simple tactic, yet it will give you the peace of mind of knowing that your photos and most important computer files are being safely protected.

The Basics of Cloud Backup Services

Cloud backup services allow companies and individuals to have instant access to electronic documents, photos, music, videos, and any other file. This remote access is a critical innovation of the technology age that simplifies file storage. Cloud processing is based on shared computing resources rather than physical servers and hardware. Basically, it allows data to…

Cloud backup services allow companies and individuals to have instant access to electronic documents, photos, music, videos, and any other file. This remote access is a critical innovation of the technology age that simplifies file storage. Cloud processing is based on shared computing resources rather than physical servers and hardware. Basically, it allows data to be stored and accessed online by many individuals from multiple computers and devices without the need for physical servers. With this technology, any individual or company can create a secure virtual backup of all files and data, accessible only to those with clearance. The main advantage is that despite what happens in the physical world, from a server crash to spilled cup of coffee on a computer, valuable data is safe and sound in the virtual world.

If you've been considering the cloud, consider these factors when selecting your service provider:

Storage

Before you look for a provider, determine how much data storage you need. The cost of backup services is directly affected by the amount of storage space you order. Before you start shopping for a provider, consider the size of your data and how many gigabytes or terabytes you wish to purchase. A terabyte is a unit of information equal to one million million bytes. Documents take up less virtual room while content, such as photos and videos, require more space. With a variety of options, there is a plan that will match your data storage needs.

Uptime

Uptime is the amount of time a computer, or computerized system, is operational. The purpose of utilizing virtual computing is to have your data instantly available anytime, so when selecting a provider pay attention to their determined uptime.

Security and Disaster Recovery

The security of your business files should be of utmost importance to your backup service company. Hackers and cyber criminals are becoming increasingly sophisticated, so be sure to ask vendors how they protect client data. For the safest options, look for a 256-bit encryption for data, both while stored and while being moved or retrieved, as well as for local and off-site storage. You should also inquire about the company's disaster recovery time. The provider should have an up-to-date policy for getting data back online in the event of a cyber attack or grid-wiping natural disaster.

Backup Frequency

If you've ever lost vital document changes because you neglected to save the latest version, you understand first-hand the importance of backup frequency. Backup frequency reiterates how often your provider will update and save changes to your data. This addon is not critical, but it could save you lots of frustration.

Pricing

Charging policies for these services are simple. Businesses are charged according to the amount of storage needed and their chosen features. Tech companies are available in a range of sizes. Some offer monthly payment plans starting as low $ 9.99 while larger providers offer only yearly payment options starting around $ 800.

Terms

When choosing a vendor, pay attention to the fine print. Be wary of service limits and lock-ins. Vendor lock-ins can prohibit you from canceling service and can make it difficult to switch providers if your business requirements outgrow the provided service.

If virtual storage looks right for you, the best way to find service providers is to do an online search. There are tons of tech companies with a variety of specialties, including cloud backup services. Call a few numbers and shop around with this article in mind before deciding on the best choice for your needs. Good luck!

Cloud Services Can Benefit Your Business

There are many types of cloud computing services available. To determine the right one for your business, you'll need to evaluate several variables and your individual needs.

There are many types of cloud computing services available. To determine the right one for your business, you'll need to evaluate several variables and your individual needs. This article defines three types of cloud services and includes tips for finding a qualified vendor.

There are three basic types of computing packages available: software, infrastructure, and platform.

Software As A Service (SAAS)

This basic option provides your business with storage software, which runs from computers and virtual servers managed by your provider. Your data is accessible to you over the public Internet with verified login information. Cloud-based software services are typically offered on a monthly or yearly payment plan.

Infrastructure As A Service (IAAS)

IAAS offers your business with a computerized infrastructure consisting of computing, storage, networking, and security tools. These features are accessible to your business through your provider, via Internet, VPN, or a dedicated network connection. You'll manage your own operating systems and applications and pay according to your usage amount.

Platform As A Service (PAAS)

This alternative provides your business with an entire platform. If you choose a platform, you'll receive all the software and hardware you need to create and utilize personalized features and cloud-based applications to bring your business to a new level of efficiency. All the tools you need will be provided by your vendor through the Internet, VPN, or a network.

Use these tips to find a reliable service provider:

Uptime

The amount of time a computer is up and operational is referred to as its uptime. Cloud services allow your data to be instantly accessed at any time, however, the higher a provider's uptime, the more available your data.

Disaster Recovery

In the event of a cyber attack or weather blackout, you need to be sure your data is back online as soon as possible. Ask all possible hires about their disaster recovery time and policy.

Backup Frequency

If you've ever forgotten to save a document and lost important changes, you've witnessed the importance of backup frequency. Backup frequency is the frequency with which your provider saves updated data. The more often your files are backed up, the better. You want the most recent, accurate information possible.

Security

Business security is one of the most important factors to consider when choosing a vendor. Make sure data encryption is offered to protect sensitive files, such as payment and finance records, and ask for security features. Do not accept anything lower than a 256-bit data encryption.

Terms

Before signing any contracts or agreements, be sure that all terms are explained to you and well understood. You should never enter a contract without reading the fine print. Avoid agreeing to service limits, which can block you from certain features and end special cloud services after a limited period of time. You should also look out for lock-ins in your contract, which make it difficult to change vendors when your business needs grow.

Cloud technology is a business feature of the future, which is quickly becoming a necessity. Do not be left behind! Beginning searching tech companies today and learn how the cloud can benefit your business.

Common Causes of Computer Hard Drive Data Loss

The data that we store in our computers are saved in the hard drive. Over time, the drive can undergo the usual wear and tear, making it unacceptable to malfunction and failure (like any fast moving parts used for months or even years). Let's examine some common causes of lost data Hardware problem or physical…

The data that we store in our computers are saved in the hard drive.

Over time, the drive can undergo the usual wear and tear, making it unacceptable to malfunction and failure (like any fast moving parts used for months or even years).

Let's examine some common causes of lost data

  1. Hardware problem or physical damage on the hard drive. One of the most common causes of data loss is hardware problem. The hard disk can suffer from bad sectors, which can be physically damaged. Once damaged, the needle, which reads the hard disk, can no longer read these bad sectors. Physical damage such as trauma on the drive can also cause lost information. The moment the drive no longer opens or boots, then the data can no longer be read, leading to massive loss without recovered. Physical damages can happen when you drop the hard disk, or spill water or any liquid in it.
  2. Power outage or interruption. The computer has two types of memory – the Random Access Memory (RAM), which stores the temporary data, and the hard drive, which stores the permanent or saved data. In cases of power interruption or power outage, the data in the temporary memory or RAM is usually lost. In several cases, however, even the saved data in the hard disk can be corrupt or lost upon a power interruption. The corruption or loss of the file may be due to the interrupted proper reading of data from the drive to the RAM. Apart from power interference, extreme heat can also cause the computer to shut down, which can also lead to lost data. Improper shutdowns can also cause loss for the same reason stated above.
  3. Improper ejection of removable devices (USB drives etc) – Improper ejection can also cause data loss. The device might still be reading the data when the user abruptly removes or ejects the hard drive, much like when there is immediate power outage or interruption. This is the reason why you should always safely eject your external drives.
  4. Computer viruses. There are a lot of computer viruses that can infect the computer and cause data loss. Downloading files from the internet can expose your computer to viruses and malware. The Trojan virus attacks the data in the computer hard drive, rendering it vulnerable to hackers and other viruses. Viruses such as this can cause lost information / data too.
  5. Bad programming – A programmer encodes human instruction into a language that is readable by the computer system. In cases when a programmer commits logical mistakes or erroneously executes a program, it can delete existing files in the computer. Logical errors by the programmer can also occasionally cause lost data.

What else can you do to be proactive about securing your data and preventing frustrations down the line? 6 tips to prevent data loss

Bandwidth Is So Cheap, Why Do I Need WAN Optimization?

Bandwidth is no longer a fancy and expensive requirement for networks. Thanks to competition among bandwidth providers and developments in technology, bandwidth is constantly getting cheaper.

Bandwidth is no longer a fancy and expensive requirement for networks. Thanks to competition among bandwidth providers and developments in technology, bandwidth is constantly getting cheaper. As a result, upgrading bandwidth is often the first solution many IT engineers and system managers think of when faced with WAN problems. The question is, does upgrading your bandwidth ultimately solve these problems?

Speeding up data transfer

Upgrading your bandwidth throughput can speed up data transmission when a lot of data needs to move at once, but widening the pipe is not always enough. There are times when your WAN will still be slow despite not using all of the available bandwidth. Why? Latency.

Latency is the time needed for a packet to travel from one designated point to another. The farther the distance that data has to travel, the higher the latency is. Because packets and acknowledgments of receipt are moving back and forth many times to move a file or interact with an application, the distance between the two points ends up being the limiting factor for WAN speed.

WAN optimization solutions improve the transmission control protocol (TCP) to minimize the effects of latency. This decreases the time to send and receive data, which in turn increases speed of data transferred. WAN Optimization Controller can improve WAN speeds as much as 60X.

Improving application performance

Similar to slow data transmission, when an IT manager obtain complaints about a slow application, they may think that a bandwidth upgrade can solve the problem. Once again, if latency is too high, increasing the throughput will not improve application performance. Moreover, poor bandwidth management could be the problem. This is when one application uses up most of the bandwidth while other critical applications have to share the reminder. Even if you add more bandwidth non-critical applications will often bloat to use up much of what you gained.

Physical WAN Optimization Controllers allow IT administrators to prioritize bandwidth for business-critical applications and restrict bandwidth for non-essential traffic. This ensures that important applications are work quickly and are not interrupted by recreational or other non-essential applications.

What's better for the IT budget?

There is a rumor that upgrading your bandwidth is easy and cheap. All you need to do is increase the monthly fee; no CAPEX required. Upgrading your bandwidth CAN help when you are using all of your available throughput, but this is only a short-term solution.

As your company grows, so do its data and application needs. Occasionally, backups and application traffic will overtake your bandwidth upgrade. Not to mention that many instances of “slow internet” are results of problems that do not even involve maxing out your bandwidth throughput.

WAN Optimization is a long term investment. Since it improve speeds through deduplication, compression, and increasing TCP / IP efficiency, the benefits will last much longer and scale better with your business. Once deployed you can use it for years.

As for cost sensitivity, some vendors offer tailor solutions within the budget of an SME with flexible deployment methods (physical or virtual) and payment options (Monthly, Annually, or Perpetual).

Why Data Recovery Is Virtually Impossible On Internal Solid State Drives

Did you know that when your computer deletes a file, it might not really be deleted? Instead, your computer has simply…

Get a better understanding of why External Hard Drive Recovery is challenging, so getting it done by a team of professional engineers becomes more important as they safely and accurately do the data retrieval.

Did you know that when your computer deletes a file, it might not really be deleted? Instead, your computer has simply marked the file as unimportant. If your computer marks a file unimportant due to accidental erasure, this can cost local businesses more than £ 12 billion a year for data recovery and to upgrade security against accidental file deletions. However, this may not be the most frustrating part of accidental file erasure. If a computer marks a file as unimportant, your operating system may rewrite these sections anytime that it needs more space? However, if there are bits of unused space in an empty sector, this can be as quickly recovered as the amount of time it takes to recover a sector that has been used and overwritten. However, the process works differently with solid-state drives.

Before data can be written in a solid-state drive, a flash memory cell must be clear. Since new drives are empty, they easily can be written. However, on a full drive, there are written files with bits of deleted files lingering around. Writing to a drive takes longer because the driver writes the information much slower. This also means that the driver naturally slows down over time.

Solving the writing problem and protecting Data

The trim was introduced to solve the problem of a driving being slow to clear sectors, so that new data can be stored. However, a Trim command helps protect data because it makes it almost impossible for data on internal solid-state disk drives to be deleted. This does not apply to External Hard Drive Recovery though. Why does not Trim work over USB drives or Fire wire interfaces? The Trim command is not supported on these formats.

This may be good news for businesses, who 58 percent of employees admitted to causing security breaches, no doubt due to accidental data erasure. This means deleted files can be recovered from external hard drives because the files are sitting in memory, waiting to be retrieved. However, this also can mean that these files are as vulnerable as traditional magnetic disk drives, since the data can be recovered and still fall into the wrong hands. The goal is to make sure the safe and complete recovery of your data after it has been lost due to a hardware, software or firmware issue.

Customising Mobile Solutions Should Be An Important Part Of The Disaster Recovery Plan

Employees are moving from using laptops to using mobile devices to offer workable solutions from everywhere, but many companies are not up to the challenge. This year, most IT techs have admitted their companies had no policy for using mobile devices. Company heads noted mobility was one of the key initiatives this year. As professionals move away from traditional PC endpoints, how can companies protect sensitive data and develop a strategy to recover from data loss?

Why are companies not dedicated to protect sensitive data in many cases? Many companies are using outdated solutions for information recovery for hard disk recovery that address recovery more than mobile solutions. In one survey, only 58 percent of business professionals admitted their companies had an enterprise-wide strategy for mobile solutions. Another 22 percent said mobile initiatives were important, but they had no strategy next year.

Why is it so difficult for companies to protect endpoints before data are lost

Many companies have updated their advanced data disaster recovery plans, offered hard disk recovery, and have mobile solutions on paper. They have not decided how to transfer these solutions so they are practical daily solutions, which will protect against data loss and still offer data recovery. Many companies struggle to offer flexible and secure solutions for mobile devices and laptops make endpoints safe, and reduce costs spent on hard drive recovery or hard disk recovery solutions. One of the reasons is that they are not equipped to handle how customized IT solutions have become.

Fifty percent of businesses say it is difficult to achieve data loss protection as a result. Why is it hard for businesses to protect against data loss and less the costs of HDD recovery or data recovery? It may be for the same reasons companies struggle with mobile Information recovery from Smart phones and laptops. There are no data recovery plans that are one-size fits all solutions. Companies must develop specific data recovery solutions for each type of device to offer full endpoint protection against data loss.

Achieving endpoints for PC tops list of goals that are still difficult for companies

By developing these advanced data recovery plans, company officials will also reduce the costs spent on HDD recovery, data recovery, and downtime caused by lost productivity. These changes must be made quickly if companies want to stay competitive with their products and not lose customers over data loss concerns.

A variety of reasons exists as to why your computer's hard drive may cease to work. The outside chance of a bump against it as someone in the office walks by, spilling something on it or simply the result of general wear and tear.

Using Data Recovery Software Does Not Mean Data Recovery In The Local Area Will Be Successful

It is easy to think data recovery software will solve hard disk recovery problems, but software does not always do the best job with data recovery in the local region. Do you an already have a duplicate copy of the software, stored somewhere or a virus has damaged your files. In these cases, it may…

It is easy to think data recovery software will solve hard disk recovery problems, but software does not always do the best job with data recovery in the local region. Do you an already have a duplicate copy of the software, stored somewhere or a virus has damaged your files. In these cases, it may be easier to perform data recovery, using the software. If your problem is a hard disk drive itself, running software is a bad idea.

Software is not going to help perform hard disk recovery on a hard drive that is failing. The software is not designed for this type of recovery in local area and it could cause further damage to data, especially if the data is taken to a data recovery specialist after running a software program.

The real reason software does not work on a failed Drive

Information recovery in the present area is serious business and running software for data recovery or Raid recovery may cause the data to be irretrievable. What happens when software does supposedly retrieve your data? It scans media and logic data blocks looking for information, but it also can be causing damage when it does this. A computer user can have a sector error because of this. What if the computer fails to respond to this hard disk recovery and freezes ?. Hard drive heads for reading and writing will click and spin, without accessing needed data. However, then this action will cause damage and data will be lost.

Some computer users are simply looking for cheap data recovery in the area. However, such types of hard drive recovery solution is not suitable in every situation. If not used properly, it could cause more harm than good. It also could mean a professional that specializes in recovery in regional area can not retrieve the data needed, after it has been damaged by software scans.

The Limitations of using software for data Recovery

Did you know these software scans are no match for firmware infections or file data corruption. If the data is critical data, it is best not to take risks that data software will be able to retrieve the much-needed data. These software products may not work as advertised and is not it cheaper to have the peace of mind and take your computer data to a trained professional. They typically have a higher success rate and can recover data when the hard drive does decide to fail in your computer. Computer users may suffer a greater loss if they use the cheap software to try to restore essential data that is unreadable or lost. Is there software that you have found works the best for computer users, who only need to recover files after a virus? What has been your experience using software that stated it would recover lost files that were unreadable or simply missing from your computer? Before trying your own hard disk recovery, it may be better to ask a trained professional.

Ins and Outs of Removable Data Media Recovery

Students and working professionals need to transfer data for their projects. Family members and relatives share precious documents and photos with one another as well.

Students and working professionals need to transfer data for their projects. Family members and relatives share precious documents and photos with one another as well. As such, thumb-drives and portable USB drives have become almost a necessity. The proliferation of mobile technology has also engendered the burgeoning popularity of cameras and PDAs. Smartphones can double up as devices to store MP3, movies and also photos.

Typically, there are different types of removable media such as solid state memory; optical; and magnetic. Let's take a look at the different types of devices.

Solid State Memory Data Media

USB thumb drives, smart media cards, memory sticks, multimedia cards, mini SD cards and xD Picture Cards all fall under the umbrella of solid state memory data media. They are extremely light but come with a large storage capacity. They are however prone to virus attacks, bad sectors as well as condemning of file access. When they become kaput, dialogue boxes prompting a reformat will pop up.

Optical Data Media

These optical data media include CDs, mini CDs, DVD and magneto optical. In the past, they were used to store and back up important data. Problems such as not being able to access the data, missing directory information and blank information are common with this type of media. Strange characters or garbage display will also pop up. There are also times when the computer would freeze when trying to access the media files. As a result, the data becomes unreadable.

Magnetic Data Devices

Floppy diskettes, Iomega Zip or Jazz disks fall under these categories. Once popular and ubiquitous, they have now become increasingly rare. The devices are made up of soft data platter -right where the data is stored magnetically as bits and bytes. They are susceptible to physical damage as well as dirt contamination, which come after prolonged use. The common problems include errors such as “disk not formatted”, “click of death” which results in accessibility to access the media and freezing of system.

Recovery

It is important to note that the data is recoverable. When data loss occurs, it is critical to stop all operations on the device and do a proper ejection. Any attempts to fix the disks may cause further damage without the help of a professional. Always seek the expertise of a certified technician. He will be able to help you recover the data safely, lowering the risk of unrecoverable situation.

Why Is It Not Possible To Easily Recover Data On A Hard Drive That Is Overwritten?

Many people may think that data are missing and a professional can still perform Raid data recovery or hard disk recovery. In reality, the data has not been removed. A computer hard drive does not know how to locate the data. The information, which tells your computer where to locate the data, is missing. This…

Many people may think that data are missing and a professional can still perform Raid data recovery or hard disk recovery. In reality, the data has not been removed. A computer hard drive does not know how to locate the data. The information, which tells your computer where to locate the data, is missing. This is also the reason why the best professionals who perform laptop data recovery or hard disk data recovery can not locate important files after a drive has been reformatted.

How do professionals find information to perform hard disk recovery if you have not reformatted a drive and had it overwritten? These hard disk drives store information magnetically and do not require anyone monitoring the information on the drive. Those strings of data in eight 1's and 0's may look like gibberish, but a hard drive can use those 1's and 0's to keep stored data separate.

Hard drives use magnetism to store Information

Similar to a car battery, hard drives have magnets that have a plus and minus pole. The poles represent the binary code 1 and 0 is a computer uses. The HDD storage unit or platter contains a magnetic surface and divides the binary codes into magnetic regions, called magnetic domains. Data is stored by the direction of the magnetism of these domains. The magnetic domains are magnetised in one of two directions and represent a 1 or 0.

Data is stored in two ways on a HDD unit. Before 2005, this data was recorded parallel to the disk surface, meaning the binary code was either recorded with left or right magnetism. This type of recording was called longitudinal recording. Around 2005 and later, this magnetism used to record binary code has been used to record segments being recorded vertically and perpendicular; it is called perpendicular recording. It adds a layer to the recording process and the magnetic domains are stored closer together.

Why your computer can not find your file and what happens when data is overwritten

You can not find your file and sometimes, you take your computer into a professional who is skilled in laptop data recovery or hard disk recovery and they can not find your files either. If your data has been overwritten, the best professional in the world, even if they are good at Raid data recovery, can not help you.

Your computer may not find data because it has written over the stored data. The files are located using a table on your computer and rather than delete the information in the file, your computer marks the space where the file is as void. By doing this, it is able to write over the existing data and this is why the best Raid data recovery specialist or hard disk recovery professional can not retrieve your files. The operating system writes over old data with new data, essentially deleting it.

Laptop data recovery is a long shot after data is overwritten

Your information may be recoverable if it has been overwritten. If data has been overwritten, the magnetic domains are changed through re-magnetization. The process is not reversible and it is slim recovering data because it would require the use of a magnetic force microscope.
