Getting data from multiple policies onto one tape 1

[NATD]

Hi,

For the past few months I've been getting stuck into CommVault (6.1) and have pretty much finished removing all traces of ARCServe from my environment.

The setup is basically the CommCell with FC attached magnetic library and LTO3 library. Currently, all clients come thought this media agent (18 in total, 10 are branches doing incs and syn-fulls over slowish WAN).

I've ended up with 3 storage policies
BRANCH (incs to disk only and weekly syn-full to disk and tape)
HO Disk+Tape (all incs and full to both disk and tape)
HO Tape Only (this uses the mag lib as a spool copy for both incs and fulls to tape)

I'm pretty happy with everything other than one thing.....it uses a new tape for each policy, so I gt two tapes most days and three when the 'branch' syn-full runs.

The totaly data is quite small and will technically fit on a single LTO3 tape. I'd like to save both my daily courier costs and more importantly, the number of tapes needed.

Can it be done or do I have to accept that each SP needs a unique tape?

Thanks

Sorry to have to tell you but, each SP needs it's own tape.

Thanks - at least I can stop trying to acheive the impossible and either elt it be or think about my options to remove a policy. I've only got multiple to conserve space on my mag lib - I've got some data I'd like to have on disk for 2 weeks whereas other stuff I just want to know it's safe offsite and don't need to have ready access to it.

Am I right in thinking there can only be one set of retention & copy rules per SP? Ie I've no way of the policy saying "ah, I know that for this subclient I don't really have to retain on the disk copy'?

Yes, 1 set of rules for all associated clients.

If you want a subclient to have different retention then you'd need to place it in it's own SP.
