I have configured backups for my Microsoft SQL 2003 and 2008 R2 databases. The backup solution that I am using is DPM 2012 (I am not sure if this is a relevant information).
I am currently backing up all databases on the SQL instances including some databases with the following names:
master, model and msdb.
My question is, Do I need to backup these databases as well?
I have not excluded them from my backups because I am not sure what they are needed for.
