> Which is why for important data I always use some sort of RAID (or cloud syncing). If I lose a drive I won't lose all my data
Just a friendly reminder that RAID != backup. There are numerous data loss cases that RAID does not deal with.
Personally I use striped ZFS with important volumes periodically snapshotted, replicated to external (and encrypted) disks and then stored offsite (cycle through a couple of sets of disks). Most important data is also periodically synced to cloud storage (as well as offsite disk).
This accounts for:
- Single disk failure (striping)
- Bitrot (ZFS scrubbing can reveal bitrot on disk and correct it from parity)
- Human error (snapshots)
- Catastrophic damage to home NAS (offsite backups)
RAID alone (depending on the particular implementation) will generally not deal with the 3 latter failure cases.
