Thanks for the idea. My goal was to capture the snapshot subdirectory they way it was on that day. Specifying the snapshot I want to backup would be no different than selecting a different time to run the backups.

Hi Jack,
One other option you can consider is specifying an existing snapshot as your NDMP backup source. For example, if you configured your filer to take nightly snapshots at say 11:00pm and had your scheduled NDMP backups start at sometime after that, then you could configure the backup job to use the "nightly.0" snapshot as the backup source. When a snapshot is specified in this way, NDMP driven dump will not create another one for backup.
Any backup software should allow you to define a job that uses an existing snapshot (or a snapshot that will exist at the time the job will run) for backup. Of course it's simplest if you configure the job to use a static snapshot name rather than one which will change each time the job is run so NetApp scheduled automatic snapshots will work perfectly.
HTH.
Kevin

I guess that makes sense. it would have been nice to be able to look restore a snapshot directory from 4 months ago!
It looks like I could do a monthly snapshot manually and see how much
space
it takes up. Right now, my snapshots are only taking up 23% of the space allocated for snapshots. I am going to experiment with taking 6 "monthly snapshots"

Hi Jack,
The snapshot directory is not included as part of the NDMP dump. When the filer is told to do an NDMP dump, it actually takes a snapshot, then dumps the data from that snapshot.

that the backups might have included the snapshot directory but it didn't? Is that configurable?
