Scratching my head again. I want to do regular snapshots of my system on a separate backup server (in a different location). I run the following on the backup system:
The copy is fine, and the stuff shows up:
So now if I want to find/restore a file from the copied snapshot, I have to mount it. I want to mount it on /mnt/backups. I thought this would work:
but the result is not what I expected:
So the mount point for zroot/backup and zroot/backup/home changed, but not the others. I would have expected either only zroot/backup to change, or all the ones under it.
What am I missing, and how do I recursively change the mountpoints of everything under zroot/backup?
Code:
ssh root@SERVER zfs snapshot -r zroot@$DATE
ssh root@SERVER zfs send -R zroot@$DATE | zfs recv -uvdF zroot/backupThe copy is fine, and the stuff shows up:
Code:
$ zfs list
