How do we configure staging in EMC Networker based on saveset or group or backup
Hi,
In one of the implementation we have deployed EMC Networker with Data Domain for all the backup of HyperV, Exchange systems. For the secondary backup Tape library is been used. Now client wanted to have staging to be done weekly basis based either on the weekly backup or based on Save set. But we dont see any option available in Networker except on high water mark or % based staging.
Please let us how do we get this stating configured either based weekly backup or by using savesets to Tape.
Thanks
Prasad

It is either high watermark or age of ssid (which comes first). You can also trigger it via script from CLI at any time you want.

Hi Crvelin,
Thats the problem when multiple backups saved in Data domain if we do staging based on age or water mark how do we bifurcate and see the backup files in tapes as per the weekly, monthly backups.
Networker doesnt have option to create the staging policy according to saveset or accordingly to backup type (weekly or daily)? If this is the limitation of the product so is there any alternative for this problem?

It is not limit of the product, but rather aligned with market thinking of backup. You would always use scheduled staging if you had to free up space and that would be based on watermark or age on volumes. If you want cherry picking, no problem, but you need to go to CLI level. From there create list of ssids to be moved with mminfo and use that as input for nsrclone -m

Thanks for the quick reply, so if we don't use CLI but use the GUI based staging using water marks, can we see the contents of staged data of all backups taken earlier in tape? Also can we restore the data from tape directly to servers if Data domain goes down.

From GUI, staging works with volumes and not ssid collection/selection. It's selection is solely made based on watermark or age. You can query via mminfo or GUI specific saveset and learn about its location. When data is staged, it lives on target medium only (your case tape) so when you run restore, you read directly from tape (no need for DD or any other medium in between).
