Backup Central

Hello-
I have a question on aux copies to tape. We currently are using an IBM tape library with two LTO3 tapes presented to CommVault. My problem is the aux copies are taking super long to run. (I have about 7 separate storage policies all writing aux copies to tape) I will not be able to add additional tape drives to CommVault for a while so I was thinking of using the de-dupe to tape option. Can anyone give me their thoughts on this? My de-dupe license mode is CDSA so I should be covered from a license side, just wondering if anyone is doing it?

Thanks,

I was thinking of using the de-dupe to tape option. Can anyone give me their thoughts on this?

My five cents: Don't use CommVaults dedup to tape (SILO backup). It's very complicated to configure correctly, you will probably get all kinds of troubles, among others with data aging.
I would try to find out why Aux Copies take so long. Perhaps you can use multiplexing?
