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?
