snapvault.

snapvault snap sched myvol sv_daily 5@-

say its oracle on the host:

backup script puts instance in hotbackup mode snapvault snap create myvol sv_daily backup script takes instance out of hotbackup mode

(cold backup shutdown/startup same way)

it will automatically keep 5 snapshots rotate the oldest and the - allows you to take the snap anytime via the script

Everyone is assuming that the NetApp will be taking the snapshots, which is incorrect. I must do the snapshots from the host side in order to quiesce the filesystem (actually, the database). My databases run on LUNs over FCP. I do not want to try and coordinate the databases on the host being quiesced at the same time the filer will automatically take the snapshot.

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

Any reason you can't use the "snap sched" command for this?

snap sched volname 0 3 0

This takes a snapshot at midnight and keeps at most 3.

If midnight isn't suitable you can configure the hourly option to take one hourly per day and keep 3. Suppose you want 18:00

snap sched volname 0 0 3@18

Hi Daniel --

Protection Manager can do what you want. You can configure a script to run before creating a snapshot which could quiesce your application. Protection Manager will take care of creating the snapshot, deleting old ones and running it all on a schedule.

I have had a case open with NetApp for a while now asking about the possibility of an auto-deletion option for retaining N snapshots regardless of autodelete policies in place. This is the safety one needs to use the mechanisms that drive auto-deletion without potentially allowing the removal of _all_ snaps. I don't ever want all my snapshots gone unless I specifically ask for that.

Daniel, You can set snapshots to automatically delete via the filer. If you want to delete the oldest snapshot then take a look at this: http://now.netapp.com/NOW/knowledge/docs/ontap/rel724/html/ontap/onlinebk/2s...

Thanks Chris Nowak
