Data Protection Manager Protection Groups

Hi Experts,

I want to reorganize my DPM 2010 configuration.

I have a tape library directly connected to a DPM 2010 server, wich contains 22 usable tapes. At the moment i have about 25 servers, devided in 5 Protection Groups. Tape co-location is enabled.

I figured that all selected data sources of all servers in all protection groups, fit on 1 tape. However, with co-location enabled, DPM sometimes fills up a previously used tape, before using a free or expired one.

Now my question;

Is it smart to put all the 25 servers in 1 single protection group and disable co-location?
In that way everyday only a single tape is used for all the backups. Also the weekly backups will only use 1 tape. It creates a nice overview for me. All servers can use the same schedule.

What is your opinion on this?

Hi,
i guess that as long as it is more manageable for you you should choose that policy, that is only one policy for all 25 servers.
The only counterpart is that if you go incremental all servers will span multiple tapes, and this means that a restore of a single server will take longer because autoloader must mount more than one volume. But i guess that is not your case, that is you're doing full backups everyday, and you're own suggestion is optimal
hope this helps
