Hi Team, I've got a question around best practice for backing up my SCCM 2012 environment, currently we have have an SQL backup that runs everynight, and we have SCCM doing site backup daily, our DBA is now questioning why we doing this SCCM Site backup as well as them doing the SQL Backup, is both needed in  DR scenario? What is the correct process we need to follow in our Enterprise please?

Hi,

There is (almost) always a battle between SQL DBA's and SCCM guys it seems. The facts are simple:

1) SCCM is not a normal SQL DB (see below)
2) SCCM stores key information all over the place, including the registry, WMI stores, files and SQL - *just* doing a SQL backup will leave out your content library and the source files. If you want to do a full "site restore" a la DR you need to cover both.

Reading material: anything by Steve Thomspon MVP
Starting with ConfigMgr 2012 Sp1 and later, using native SQL Server backup tasks is another valid option to backup only the ConfigMgr site SQL database

SQL Config
Full database backup is all that is required and for your CM, SUSDB & Reporting databases you should be running them all in Recovery mode = simple, so the transaction logs are not needed (and waste precious disk space).

With SP1, MS made the native SQL backup better. Apparently the CM maintenance task needs to stop CM, whereas native SQL you can leave it running.
I think most CM admins are moving to SQL + file backup instead of the CM maintenance task (from what I've seen).

So your DBA is correct that you don't need both *IF* you are running 2012 SP1 or later (which you didn't say).

To keep your DBA really happy (and assuming they don't already have the scripts), the new advice is the need to do SQL tuning (that MS themselves use internally), optimising indexes and other SQLy things.
