Wondering if you do any checking for bitrot? I mean, if some files on one of your disks became corrupt over time how would you know before it becomes too late to recover it from older backups?
- squarefoot 4y agoI'm no sysadmin so my knowledge in the field is limited. I'm relying on ZFS mirrors which hopefully should be a bit better than the alternatives at bit rot protection, but admittedly if I was hit by corruption at that level that would catch me unprepared. I'm open to suggestions however.

I have one cronjob that once a month runs 'zpool scrub mypool' to validate all checksums as a bitrot test, and then a day later another one to email me the results of 'zpool status'. If that email contains "state: ONLINE" then no issues were found. But I've pieced this together myself and would also be open to anyone's suggestions!
