Unraid checking in. 150TB ish. Dual parity for media files on XFS drives. Can lose 2 drives before array data is at risk, and even then if a drive fails, I’d only lose the data on that drive not the entire array.
Important data is on ab encrypted ZFS array which is snapshotted and replicated hourly to a separate backup server and replicated one more time weekly to 3.5” archive drives which are swapped out to a safe deposit box every few months.
I used to use rsync to do it but snapshot replication with sanoid/syncoid does the same thing in a tiny fraction of the time by just sending snapshot deltas rather than having to compare each file.
Well said. I run a mikrotik router for my main network and use unifi APs throughout my house. Took a lot of tinkering to set up and I learned a lot. Very flexible but more expensive and much harder to learn than a simple all in one setup.
