What are the *-dst.0 files created on snapshot volume

sa_200099 — Thu, 05 Jun 2025 06:56:31 GMT

Hi,

Occasionally notice that these files are left around when snapshots are cleaned up and the owner appears to be unknown.

snap list -b Backup1

Volume Backup1
working...

name owners
------------ ----------

dataVolumeOne-dst.0 unknown

Is this some type of NetApp temporary file? Any best practice to clean up such files?

Thanks,

-=Marty

Hi Marty

I only saw "-dst.0" Snapshots on Snapvault-/SnapMirror-Destination Volumes. Is this volume part of a protection-/dr-relationship?

Kind regards,

Adrian

Hi Adrian,

Yes, the -dst.0 files are on a secondary storage volume where backup data was transferred to the volume via NDMP.

Perhaps this message title should have referenced secondary volume, instead of snapshot volume...

Best,
