Just got my first FreeNAS (v 9.10.2-U3) system up and running and I'm looking for a bit of explanation surrounding recovery techniques.
We've got:
1. Snapshots
2. System->Advanced->Backup
3. Replication tasks
4. Rsync tasks
Is there anything else I've missed?
My goal with this FreeNAS is primarily data integrity, and preventing against data loss. I have a raidz2 configuration composed of 4 2TB disks and I want to make sure that if 3/4 drives were to fail that I still will not have lost any data or that I'm able to restore to some recent state.
My understanding/questions-
1. I understand that snapshots are not a backup and that they are just there to allow me to restore the pool back to the way it looked at a previous point in time (or recover a lost file(s) without actually rolling back to previous state).
2. What is this?
3. This a complete backup of a zfs pool based on a particular snapshot. How is this intended to be used?
4. Copies data from on system to another over the network, is this pretty much the same as a replication task?
