I have a 2 bay NAS, and I was planning on using 2x 18tb HDDs in raid 1. I was planning on purchasing 3 of these drives so when one fails I have the replacement. (I am aware that you should purchase at different times to reduce risk of them all failing at the same time)

Then I setup restic.

It makes backups so easy that I am wondering if I should even bother with raid.

Currently I have ~1TB of backups, and with restics snapshots, it won’t grow to be that big anyways.

Either way, I will be storing the backups in aws S3. So is it still worth it to use raid? (I also will be storing backups at my parents)

    If you needed to spend any time “setting everything back as before”, you didn’t have a full backup.

      the reason OP was thinking of doing this, was saving disk space and avoiding buying another hdd. So if it’s a 1:1 full disk image, then there’s almost no difference with the costs of raid1. Setting exclusions, avoiding certain big files, and so on. In this case he’s talking about restic, which can restore data but very hard to do a full bootable linux system - stuff needs to be reinstalled
