In vSphere 5.1, we created a backup of a VM using NetApp VSC (storage backup). It appears that NetApp took a snapshot of it -- smvi_Bkup_novmsnap_20131205130001 -- see below.

i1whlnetapp02> snap list Napp02_vol2
Volume Napp02_vol2
working...

  %/used       %/total  date          name
----------  ----------  ------------  --------
  5% ( 5%)    4% ( 4%)  Dec 06 08:00  hourly.0
  5% ( 0%)    4% ( 0%)  Dec 06 00:00  nightly.0
 10% ( 6%)    8% ( 4%)  Dec 05 20:00  hourly.1
 11% ( 0%)    8% ( 0%)  Dec 05 15:05  i1lvnetapp01(1883808135)_i1lvnapp02_vol2.3829 (busy,snapmirror)
 26% (18%)   23% (15%)  Dec 05 13:00  smvi_Bkup_novmsnap_20131205130001 (busy)
 26% ( 0%)   23% ( 0%)  Dec 05 12:05  i1lvnetapp01(1883808135)_i1lvnapp02_vol2.3828 (busy,snapmirror)
 26% ( 1%)   23% ( 1%)  Dec 05 00:00  nightly.1

Open in new window


We then deleted the VM.

We are now trying to delete the backup we took using NetApp VSC plugin, but we are getting this error message:

Failed to delete backup. Reason: Snapshot 'smvi_Bkup_novmsnap_20131205130001' was not deleted as it is currenlty being used by application(s) 'busy'. Please retry after sometime.

The backup was created 22 hours ago.

Is it possible that you have snapvault or snapmirror relationships on that volume that keep the snapshots "busy"?
