Taking a proper dib backup of a SLES11 OES 11 Server

Hello All,

We have a mix of servers in our environment...
SLES 10 OES 2 and SLES 11 OES11

MY question is...
I need to take dib backups but the command i was using is ndsbackup cf dibbackup
Apparently this command only takes a copy of the nds objects but not the local data base?

So my question is... how do I take a proper DIB backup that can be used if the worst happened to any one of my servers? and I needed to restore from it?

Thanks for your help
Cheers
