I am trying to get my personal filesystem in order
I want to tar everything and get it organized into proper directories
I have many HDDs and a few SSDs
I want to use Btrfs with it's checksum and redundancy features
The question I bring to you now is: How do I configure a data scrubbing daemon that automatically detects when I randomly lose a HDD sector causing an archive to not pass it's checksum verification, then to copy a backup onto another sector.
I'm under the impression that this backup can actually be on the same HDD. It's unlikely I'm going to lose an entire drive all at once with normal aging and wear. In the future I plan to expand my backup filesystem to multiple HDDs. But for now I'm interested in having duplicates scattered across multiple sectors of the same drive.
My end result is to never again have to deal with losing a random JPEG or text file
I do have multiple HDDs I can dedicate towards a single large redundant autocorrecting Btrfs filesystem. But I don't have multiple of the same sized drives
Please link me to some good reading material covering what I'm interested in here
