Its new homelab time. And with that, potentially a new OS time too.

I currently am very happy with Debian and Docker. The only issue is I am brand new to using data redundancy. I have a 2 bay NAS I'll use, and I want the two HDDs to be in raid 1.

Now I could definitely just use ZFS or BTRFS with Debian, and be able to use Docker just like I do currently.

Or I could use a dedicated NAS OS. That would help me with the raid part of this, but a requirement is Docker.

Any recommendations?

How about bitrot?

That is indeed a good question. Is this something RAID is bothered with at levels 0 and 1? I think in this case it's the job of the filesystem to care for that. But you should probably let the periodic task run that does scrubbing like once per week. You could also experience other issues than just bitrot. For example bad sectors and one of the hdds slowly degrading.

In the end I don't think a RAID1 can do much about bitrot and other RAID woes. There are no checksums or anything to correct for that. You'd probably need some other technology for that. But it's probably the same for a ZFS mirror. And everything better than that needs more than 2 hdds.

I think ZFS does some advanced stuff which makes it better than just relying on hardware checksums (which have been shown to not be so great)
