Thanks for all the quick responses. The available solutions are

a) Snapvault

b) Protection Manager

c) Scripting, which I chose to do (using snapdrive):

$SD snap create -hostvol $DB_DEVICE -snapname snap.0.tmp

if [ $? -eq 1 ] then echo "Snapshot creation returned non-zero errorlevel!" exit 1 fi

$SD snap delete $SYSTEM:/vol/$NA_VOL:snap.$RETENTION

while [ $RETENTION -gt 0 ] do ((TMP_RET=$RETENTION-1)) $SD snap rename $SYSTEM:/vol/$NA_VOL:snap.$TMP_RET snap.$RETENTION ((RETENTION=$RETENTION-1)) done

$SD snap rename $SYSTEM:/vol/$NA_VOL:snap.0.tmp snap.0

I would love if the filer's 'snap autodelete' could have the functionality in the future.

Greetings,

I take a daily snapshots (named ss-YYYYMMDDHHmm) of several volumes on my filers. I would like to automatically delete the oldest snapshot (assuming it's not busy) when a certain number of snapshots are present in the volume (ie, only keep the latest 3 snapshots). Is this possible? If not, does anyone have any scripts where it can be done from a host?

TIA,

Daniel
