You do that by removing the save set using both - the ssid AND the cloneid.

1. Verify what you have:

   mminfo -q "ssid= " -r "ssid,cloneid,ssretent,volume"

2. Delete the save set instance:

   nsrmm [-y] -d -S ssid/cloneid

3. Verify what you still have:

   mminfo -q "ssid= " -r "ssid,cloneid,ssretent,volume"

What if I want to keep the save set on our Data Domain?

same procedure.

You can identify the save set via ssid & cloneid (& volume) - it is a unique combination.

And then what do I do with the tape to make it re-usable?

**Never mind this question. Once I ran the commands the tape is now showing that it's empty.

Another question I have is why couldn't I just view the volume save sets of the tape and then choose "Change Expiration" and set them to expire today?

Some of the options and warnings on this screen worried me that I was going to delete the save set or the clone we want to keep.

Since the clone copy is on tape volume, then the only way to really "get rid of it" is to relabel the tape volume itself.  Since this will also get rid of all data on that tape, then I would advise against deleting it from the media database.

Instead, I would just mark that particular copy as expired.  Command is:   nsrmm [-y] -o recyclable  -S ssid/cloneid
