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.

@Blue_Morpho @selfhosted Thanks for posting this. Some interesting articles that I didn’t know about. The Wikipedia article on expert systems needs some work. Apart from editing, the content is fine but incomplete, and the citations are not the best. I may take a crack at contributing, or I might take a nap. The 80s-90s were my prime years as a developer of intelligent systems, including but not limited to knowledge based expert systems. One of the most successful AI tools I co-invented was SHINE, still in use today.
