Manual duplication to tape...

[Kayser]

Hi, people. I´m duplicating some images from disk to tape. There are some tapes with media status Active, in the pool. This tapes has free space, but the Netbackup is taking new tapes from the scratch pool. Are there a configuration to force the duplication to get the used tapes first?? Thanks.

What is the retention level of Active tapes?
And retention level of images being duplicated?

Hi,

Please go to master server host properties -> media -> select "Allow Multiple Retentions per media"

But before select that option please check article for impact http://www.veritas.com/docs/000014391

Thanks & Regards

I would NEVER recommend 'Allow Multiple Retentions'.
It may look like a good idea when you don't have enough tapes, but sooner or later the tapes are going to fill up.
Now you need to wait for images on tape to expire before you can reuse them. ALL images must first expire. Short and long retentions.
Rather keep the default - do not mix retentions.

Hello,

Yes agree, The allow multiple retention on media is use when you cannot add more tapes in your environment.

Most of the customers create Yearly, Weekly and Monthly volume pools. It helps to manage the tapes.

Suppose you have infinity and monthly images on that tape. The tape will not get expire till the infinity retention image not get expire. Before make changes please go through the admin guide for more information about effects.

Or you can create one volume pool for duplication and add new tape in that. It will help you to manage the media and duplicate images.

Thanks & Regards

Marianne and Tousif, the "Allow Multiple Retentions per Media" item is cleared, and I´ll maintain it.

Now, with your help, I can understand why the tapes of the pool were not being used.

Very thanks!!!
