In today’s fast-paced world, backing up your files is of the utmost importance.
Typically the majority of the crucial files you use daily to run your business are all stored in one place – your computer. Laptops and desktops have decreased in cost, and the amount of storage inside them has increased greatly over the last few years. Unfortunately having all of your data in only one place is dangerous.
Computer loss, theft, natural disaster, and accidental deletion, are just some of the ways that you can lose the data you’ve spent so long creating and accumulating. The only way to prepare for the unexpected is to have a good backup strategy in place. There are many different ways to backup your computers, and using multiple forms of backup will minimize the risk of ever losing your valuable files.
What is a Computer Backup?
The simplest definition of a computer backup is an exact copy. In the case of computer files, we are referring to copies of the original files that you have on your laptop, desktop, or external drive. Creating a backup of original content means having that data saved in two places, but it’s also important to make sure that those two places aren’t on the same type of device. For example, if you have 3 copies of a working document on your computer, if your computer crashes, you will still lose all three. This makes the backup method and medium, an important thing to consider for your backup strategy and there is also free hard drive recovery software available so it doesn’t even need to cost the earth to recover data from mac hard drive if it fails.
So How Should I Backup My Computer?
If it sounds overwhelming and complicated, then you’re starting to understand the complexity of the problem. That’s the bad news. The good news is that there are a lot of options out thereto help, and they aren’t very complicated at all, once you are a little familiar with them. Making backups is much easier and less expensive than trying to recover files from a broken hard drive. Not to mention if your hard drive has been lost, damaged, or stolen, backups are the only way that you can recover the data that was on them.
So start backing up your computer today and save yourself a lot of hassle down the road. All hard drives will eventually fail; it’s just a question of when and whether or not you’ll be prepared.
Three Kinds of Backups
There are many ways to backup your files. Even manual copies (like saving a copy to a USB drive) are a kind of backup, they just aren’t a very good kind, because you have to do it manually, you have to do it repeatedly, and you have to manage things like deleting and renaming files. A good backup system is as easy as possible (so you’re more likely to use it) but the best backup systems automatically perform incremental backups so you don’t need to think about it or remember to do anything about it once the system is set up.
A Bootable Backup (or “Clone”)
A “bootable backup” (sometimes called a “clone”) is like a spare tire for your car. If you get a flat tire, a spare will let you finish your trip or at least get you to the point where you can get more help. A clone is a complete copy of your computer’s primary hard drive (sometimes called a “boot drive”).
If your computer’s primary drive died tomorrow you could hook up the clone, reboot your computer from it, and have immediate access to not only all of your files but also all of the software you use, including all of the settings and configuration changes that you have made.
If you are in the middle of an important project or just don’t have time to replace the boot drive immediately, a clone can really save the day. A clone also has a copy of all your files as they were when the clone was last updated, which means that if you accidentally deleted a file, you can copy it back from the clone to your boot drive.
A spare tire isn’t meant to be used for very long, and it usually isn’t as good as the original. The same is true of a clone backup drive. With a car there are lots of other things that can go wrong besides the tire failing. With a computer there are lots of other things that can go wrong besides the hard drive failing. Your computer will run slower when booted from an external drive, and there may be some other shortfalls.
Still you’d definitely like to have a clone when your primary hard drive fails. Of course your clone will only be useful if it has been updated recently, because otherwise it will be missing files. However, because it has to examine every file on your computer, it can take awhile to create, and it is best not to use your computer while the clone is updating. Due to all of those factors, a clone is usually updated once a day at most and more often only once a week.
External Backup Drive
You can also use an external hard drive to create an archive of your changed and deleted files. An archive is different from a clone in a few ways: first, it isn’t meant to be a bootable backup; second, it isn’t limited to a “snapshot” of your entire drive at one point in time. Instead, it creates incremental backups, which keep up with you as you work.
External drive backups are mainly intended to provide a backup of your personal files, especially irreplaceable things like pictures. Instead of looking at your entire hard drive, this type of backup only looks at certain folders, such as your home directory. The archive part of this type of backup means that if files are on your primary hard drive are changed (or even deleted) you can go back to undo the changes and even recover those deleted files. If your computer dies you can simply plug the external backup drive into a different computer and immediately have access to all of your files, as well as the history of changes and deleted files.
Most external drives for PC come with their own backup software. If you use a Macyou can buy an external hard drive to recover data from mac hard drive and use Time Machine, which will run every hour and check for changes. It will save hourly backups for the previous 24 hours, daily backups for the previous month, and weekly backups for previous months. Time Machine is easy to use, both for backing up and restoring files, but it does have drawbacks. Having to connect an external hard drive to your computer is inconvenient for laptop users who want to be able to move their computer around.
One advantage of a local archive is that there is no monthly or annual fee, and you have immediate access to all of your files in case your computer dies. However, the amount of file history (that is: how far back you can go to get previous versions of files, and how many deleted files you can recover) is limited by the size of the external drive. If you need to get a file back from yesterday or last week, you can probably do that. If you need to get a file back from several weeks ago, you might be able to or you might not, depending on how much other data is being backed up.
Last but not least: an external backup drive is still a hard drive, subject to wear and tear, it will eventually need to be replaced, at which point you will either have to migrate your data to a new drive (if possible) or start from scratch.
Having a backup (or two) next to your computer is a good start, but it still puts your data at risk for theft, fire, or other disaster. Your best protection against that type of loss is to keep another backup somewhere else. While you could make a clone and bring it to a friend’s house or your office, or even put it into a safe-deposit box, chances are that you would not remember to keep it updated because it would be inconvenient.
In fact cloud backups are the easiest kind to create and maintain. To get started you simply need to create an account, download software, run it once to enter your account information, and (optionally) set any preferences that you might want.
If you use an application like Disk Drill after the initial setup you don’t need to do anything, the software will automatically keep your computer backed up any time it is turned on and connected to the Internet.
Behind the scenes a lot is going on with your cloud backup. First your files are encrypted so no one else can read them. Then they are copied not just to one drive but to lots and lots of drives. One of the main benefits of cloud backup is that the “cloud” is made up of many distributed and redundant computers and drives, so the loss of any one will not cause you to lose any files. Once they are uploaded, you never have to worry about uploading them again unless they are changed. Even then, changes can be sent much faster because the software is smart enough to know what is different and only send the changed data.
