Can you backup to a NAS?
Well, let's define backup. A backup is simply a secondary copy of a digital asset, or more simply… a file.
A NAS is a type of centralized data storage.
The short answer is yes, you backup to a NAS. However, make sure it is a backup. Many people think their NAS is backed up because there is redundancy in the storage. That is not the case.
A RAID is not a backup. You want to make sure that if you are using a NAS for backup, it is your secondary copy of the data and you are not just relying on a RAID.
