Volumes not recycled automatically ?
Hi,
We are running Networker V7.5.1 on Windows 2003 with a Dell PowerVault 136T library attached.
As you can see below, we have a number of tapes that do not seem to be automatically recycling :
volume expires location (%)
000131L2 expired PowerVault136T full
000132L2 expired PowerVault136T full
000133L2 expired PowerVault136T full
000134L2 expired PowerVault136T full
000106L2 expired PowerVault136T full
000107L2 expired PowerVault136T full
000101L2 expired PowerVault136T full
000103L2 expired PowerVault136T full
DPN230L4 expired PowerVault136T full
DPN231L4 expired PowerVault136T full
DPN233L4 expired PowerVault136T full
DPN232L4 expired PowerVault136T full
000129L2 26/01/2010 full
000105L2 4/02/2010 full
000130L2 7/02/2010 full
000108L2 10/02/2010 full
000109L2 13/02/2010 full
DPN234L4 17/02/2010 full
000104L2 18/02/2010 full
000110L2 21/02/2010 full
000111L2 23/02/2010 full
000112L2 27/02/2010 full
000115L2 28/02/2010 full
000116L2 2/03/2010 full
000117L2 5/03/2010 full
000113L2 9/03/2010 full
000114L2 12/03/2010 full
000120L2 16/03/2010 full
000118L2 19/03/2010 full
000119L2 22/03/2010 full
000122L2 25/03/2010 full
000102L2 4/04/2010 full
000124L2 6/04/2010 full
000121L2 9/04/2010 full
000125L2 1/04/2010 full
000126L2 13/04/2010 full
000127L2 27/04/2010 full
000128L2 2/05/2010 PowerVault136T 100%
e.g. Volume '000129L2' has an expiration date of 26/01/2010, which indeed is the date of the most recent backed up saveset (26/12/2009) plus the configured retention / browse period (one month).
I think this volume should have gotten the 'recyclable' status by now (02/04/2010). Apparently, it did not.
All save sets on this volume are either windows (C:'s, D:'s, SYSTEM FILES:) or 'Networker Module for SQL sever' (MSSQL:)
Anyone any idea ?

You will need to check for dependant savesets. There may be savesets on these volumes on which other savesets (not past retention) are dependant. For each incremental backup on a volume, there needs to be a more recent valid full backup of that saveset for the saveset to be expired. Therefore, if for some reason a full backup performed after one of these incremental backups fails, then all of those incrementals (back to the last full) will not be recycled until such time as a more recent valid full backup is done. Hope this is clear.

Hi Bobby,
Thanks for pointing that out. I had thought of that before, but since we are working with a one-week backup cycle (one full and 6 incremental backups) and none of the backups have failed for quite some time now, I don't think there are any dependencies left.
Coming to think of it, there is however one backup-client (the Networker Module for SQL) that runs several times a day in order to keep the log-files under control. This could very well be the culprit. I'll have to check for the last time a full backup of the database was performed.
Thanks anyway...
Peter

Hi Bobby,
In my effort to avoid multiple full SQL backups a day, I had specified the 'incr' level in the client overrides section of the backup group (tab 'Advaced'), thus resulting in no full backup taken any more. Mea culpa, mea culpa, mea maxima culpa... Will rectify immediately.
Thanks all for your help,
Peter
