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)

    I absolutely would, for a few reasons:

    • restoring from backup is a last resort and involves downtime; swapping a disk is comparatively easier and less disruptive
    • it’s possible your backup solution fails, so having some redundancy is always good
    • read performance - not a major factor, but saturating a gigabit link is always nice
