Hi Friendz,

I just wanted to know the working of SMVI snapshot .when does the previous snapshot be removed ,is that be during the next backup trigger or next backup completion or after a retention period completion...?

Reason for this question is ,we had a retention policy of 1 day, customer requested for restore, backup failed during that day no snapshots are available there to do a restore.

Regards,

Saran

First thing to check - are there any snapshots on this volume when looking directly on the filer?

I believe SMVI invokes a process in the background, from time to time, to search through the old backups and delete them based on their retention, I do not believe it is based on when the backup runs.

This is one reason to not use 'days', and use number of snapshots for retention...
