If you got overwhelmed in trying to understand how to do it, just do it the easy way: create a ZFS pool of two drives of identical size in mirroring. Then, make sure to have regular scrubs (this means ZFS will regularly check all files for corruption, and recover from eventual errors), use your OS' task scheduler (e.g. Systemd or cron) to run this once a month. This should be sufficient to protect you from bit rot.
- OroPla 17d agoI've currently got two 10TB, one 14TB and one 18TB drive. I don't think what you describe is as easy for me as you expect. I've got one backup in a different city and one in cold storage. The sizes are all over the place because I only buy a new drive when I run out of storage and then just get the largest one within a reasonable cost. It has been cost prohibitive to mirror everything and current prices aren't encouraging. Neither is the rate at which HDDs get larger. I was kinda hoping for 100TB drives under $400 by 2025 back in 2014, but that hope has been shattered.
