Wrong. Many backup systems, on-premise and in the Cloud, are set up as RAIDs.

RAID is just a technology that can be used to mitigate the risk of data loss caused by hardware failures of physical storage devices aka harddisks.

Your convoluted sentence can be replaced by the word "redundant". And it's not just that; some RAID schemes provide redundancy, but some provide faster I/O.

With that out of the way,



I'll say it again: RAID is NOT backup. It just isn't. Just because storage systems used for backup can be using RAID does not make that any less true. Please do not pretend otherwise. There are enough people on here that don't have a clue about the difference. Please don't insult my profession.

I agree. A common mode software gremlin or malware will be replicated across the RAID discs. The only way to recover the OS then is to recover from a backup image.
