RAID 5 is quite popular as it has good fault tolerance. That essentially means that it can withstand the failure of one of its disks. As it contains error correction bits along with data striped in its disks, the data of the failed disks can be easily regenerated. Although this seems to be quite satisfying for its users but what should one do when, the RAID 5 servers crash at your workplace? Obviously, this would result in loss of confidential data for the company.

Just to deal with this, one should backup RAID 5. As no matter how many disks are added to a system, every disk has a good chance of failing. Moreover, there is 100% probability of human error occurring by which one can lose the data forever; hence, this has made RAID backing up an utmost necessity.

Where to backup?

If you backup RAID 5 in the same computer, then if the server crashes even your backup gets destroyed. A better option could be backing up the data in a data traveler and then storing it in some other machine. An external drive is very good for backing up data as well.

What data one requires backing up?

When we backup RAID 5, a copy of all data present in it such as photos, documents, spreadsheets, databases, music files, etc. gets saved in another location. So, absolutely anything important to you can be stored in the RAID can be backed up.

How often should one backup?

It completely depends on the needs of the person. A regular writer should backup RAID 5 everyday. If while writing something, there is a virus attack or a server crash, the document gets lost. A practice of regular backup of your work is required for more reliability of your important documents remaining intact.

Is there any software available for backing up data?

You will find plenty of such software. Many of these also provide you with a trial version. Some software does not even require you to create a backpack; while you are working, a copy of it is being made at the back end.

By backing up, 100 copies of the RAID array can be made at different locations. The stress of losing important data is gone forever. If you intent to back up in the same system, the copied documents can be accessed just in a few clicks!
