OK so I am trying to figure out what is the best way to create PGs in DPM 2012. From what the research I have done so far, one should create PGs depending upon the protection level and time.<\/p>\n

So, for example of you have a 5 file servers whose data should be retained for 3 months and 10 database servers whose data should be also be retained for 3 months, you should create just one single PG.<\/p>\n

Sure, you can also create two PGs, call one \u201cfile server PG\u201d and the other \u201cDatabases PG\u201d but I do not see any technical advantage of doing so.<\/p>\n

So going forward, for example, if you have a bunch of dev servers who you wanna keep a backup of for only one month, sure go ahead and create a separate PG for them.<\/p>\n

At one point I used to think that be creating 10 PGs, DPM will run 10 jobs simultaneously\u2026. but that is not true. I have since found out that DPM has a limit of concurrent jobs  which is set to 3 by default. It is a registry setting which one can change.<\/p>\n

I found this and some other, very good information here: <\/p>\n
