Retaining backups on disk before going to tape

[mulliganx]

I have a current backup policy which goes to a disk staging unit and then is duplicated to tape. 

We have duplications set for monday - friday. 

If I want to retain backups on disk for a 30 day period, how can I do this effectively while moving backups to tape as well for archiving?

you need to disable the Disk staging and use the

1) Vault  or  

2) manual duplciation ( though scrips)

to get this done..

make sure you disk STU has enough space to hold the images for 30 days.

Or use the advanced disk option with SLP. It give you the option for a " Desired cache Period".

See Admin Guide Volume 1 -page 753 : http://www.symantec.com/docs/DOC5157

With Disk Staging, retention on disk is controlled by 2 things:

1. High Water Mark when images have been duplicated

2. Retention level in the schedule.

As Nicolai said - best to have Advanced disk license so that you can config SLPs.
