Data Loss: The Facts
Backup BasicsLocal Backup
There are two types of backup available to you: local and cloud-based. The first type, local, can be implemented in a few different ways. The easiest, but least secure, way is to simply copy the files that you want saved onto a USB drive. You can copy any valuable files onto the drive and then keep that with you or in a secure location. However, while this may be a temporary solution, it is hard to keep up with all the different file versions you may have created; it is also hard to back up a large number of files.
The easiest method of local backup is to use a network attached storage (NAS). Seagate’s GoFlex Drive, for example, can be connected to your wireless network and automatically back up the data from every computer in your house. In the event of a natural disaster, you can just grab the hard drive and go - no data lost.
Another local method of backup is implementing RAID in your computer. RAID stands for Redundant Array of Independent Disks and it's a technology that allows the drives in your computer to be redundant - that is, it makes copies of your data on another hard drive installed in your computer. If you’re looking to get extra performance out of your hard drive, this will boost your processing speed as well.
RAID works in a few different ways. The first way is that it writes the exact same data to two disks at the same time. This is how most people will use it for solid local backup. Other methods for RAID require at least three disks, but offer even greater security.
The second type of backup that you can use is the newer technology afforded us by "the cloud." With this, you can store your data on servers hosted around the world, and they have their own methods of data redundancy. This offers the greatest amount of security.
The way that this technology works is relatively simple: You buy the service or, in the case of something like Dropbox, simply sign up for a user account. After this, you’ll install a program on your computer and specify the parts of your computer that you want to back up. The program will handle uploading any changes that are made to these files and upload them to the distributed hosting plan used by the service you've chosen.

However, there are a few downsides to this plan. The first is that it uses the Internet instead of a local network for backup. If you have a lot of large files, this can take a very long time to synchronize. In addition, unless you buy your own server space, you will probably have to pay for the service. CrashPlan is a good service that only costs $3 a month (as of 2012) for a single computer backup, and $6 for multiple computers with unlimited storage. If you’re a connected professional, this is a good solution.
A more complex route, but without any of the downsides of the aforementioned methods, is to use a service like Egnyte, which combines the benefits of local and cloud storage. It caches files locally so that you can use them quickly, but then uploads them for data redundancy and backup. The only downside is that it costs $24.99/month (as of 2012), although this price will support up to five users and 150 GB of data.
