There is some confusion out there on what’s a good way to back up your data. In this article we will go over several options for good ways to backup and sore your backups along with a few ways that are not recommended.

When it comes to backups storing them off site (off your server or on a secondary drive not running your system) is the best solution with storing them off site being the recommended course.

When raids come into consideration just because the drives are redundant (a lave mirror situation) there are several situations, which can cause a complete raid failure such as the raid controller failing, the array developing a bad stripe. Drive failure on more than one drive(this does happen though rarely) , out of date firmware on the drives and the raid card causing errors. Using a network storage device like our evault or a nas storege is also an excellent way to store backups off system. The last thing to consider is keeping your backups up to date. I suggest making a new back every week at minimum (if you have very active sites or data bases I would recommend a every other day backup or daily backup). It is up to you or your server administrator to keep up with your backups and make sure they are kept up to date. If you have a hardware failure and your backups are well out of date it’s almost like not having them at all.

In closing consider the service you provide and how your data is safe, secure, and recoverable. These things I key to running a successful server and website.
