Raidz2 or btrfs for important document storage? (piefed.blahaj.zone)

I currently have a secondary pool (with raidz2) that I was originally going to use for my important documents, such as storage for Paperless-ngx, as raidz offers corruption detection and repair. The pool is encrypted.

However, I'm concerned about rebuild times (it's a pool of 4 22TB drives). Is btrfs a better choice for this use case, or should I just go with raidz like I originally planned?

Edit: I should have mentioned that I already have 4-3-2 backups configured - I'm primarily interested in the "self-healing" aspect of ZFS so that I don't have to recover from backups unless necessary, and to resolve corruption on the fly without me having to notice that a file is corrupt.

Like you said: RAID is not a backup. If it's import follow at least the 3-2-1 rule. 3 copies on at least 2 different media, 1 of them off site.

Absolutely, 4-3-2 is what I use now! MDisc backups have been great.
