Jean-Louis,
I reconfigured one of my globs to use dumptype zfs-snapshot
rather than user-tar. Backups ran well but I believe that we
did a single snapshot of /export/home rather than a snapshot
of /export/home/a* for each of the 'a' directories.
I think this because when I look on the client system in the
/tmp/amanda/client directory, at the Amzfs_snapshot.20091019*.debug
files I see sepatate zfs snapshots for things like /export/samba/<shares>
but only the single snapshot for /export/home and not unique snapshots
for
[finsen/tmp/amanda/client] cd /export/home
[finsen/export/home] ls -ld a*
drwxr-xr-x 2 agaupel users 4 Aug 25 09:46 agaupel
drwxr-xr-x 2 along users 4 Sep 11 13:37 along
drwxr-xr-x 5 amanda sys 12 Sep 24 13:46 amanda
drwxrwxr-x 2 daver root 3 Aug 27 15:44 amandaScript
drwxr-xr-x 2 anarmand users 4 Sep 23 09:37 anarmand
drwxr-xr-x 2 aroselan users 4 Oct 15 10:46 aroselan
While this may work fine for a limited number of a* directories
I'm afraid of what will happen if I again try to produce a
snapshot for the b* directories.
It may be that the snapshot create fails after the first successfull
attempt, but what happens when the first glob completes dumping and
attempts to remove the snapshot ?
I will revert that glob to user-tar dumptype for the time being.
thank you,
Brian
