RAID or single drive for backups? (lemmy.world)

Basically title. Is it common to use some kind of RAID for backing up other RAIDs or do people just go with single drives?

So many people didn't read the post and going off how raid isn't backup.

There are a few things to consider. How much data is it? How is it connected? How reliable do you want it to be? Where is it going to be? How are you backing it up? How will you monitor the disk(s) and backup process for failures?

Is it at some place that will be a pain to deal with if a hard drive dies, like a friend's house or something. I'd deal with raid so it wouldn't be an immediate reason to go fix it or go without backups.

Is it small enough amounts of data that you could have a complete third copy if you didn't put the disks in raid? Then I'd probably make multiple copies and not use raid.

Are you dealing with something like veeam doing backup chains? Having an initial copy and then incremental with changes where you can go back to different days? Go with raid because having to reconfigure can be a hassle or having a full and incremental across jbods could cost you all the backups if the disk with the full backup is lost.

Either or is a valid choice and depends on your particular needs.
