  • ntbackup for DC

    my AD has a w2k3 server with an old RAID hardware, so w2k3
    sees 2 drives C: (basic disk) and D: (dynamic disk)

    This server is the only DC in AD.

    This server runs also Exchange server 2003 !

    W2K3 is on drive C: while Exchange (folder Exchsrvr) is on drive D:

    I know this is a bad configuration (I found this in the new job !)
    and I want to separate DC from Exchange in the very next future but now
    I want to make a complete backup (with ntbackup) of the system to prepare for a
    disaster recovery.

    My worksheet is :

    A. backup of drive C: together with SystemState
    B. backup of SystemState only
    C. backup of entire drive D: with VSS NOT activated
    D. backup of Exchange Information Store with VSS NOT activated
    E. ASR backup with creation of floppy

    Now I suppose that a disaster formats drive C: and drive D:

    First plan to recover :

    1.1 Boot with w2k3 CD and F2 to start ASR recover
    1.2 with ntbackup to restore from backup A
    1.3 restart
    1.4 Do I have at this moment a working DC or I must do an authoritative restore
    of entire AD database with backup B ?
    1.5 with ntbackup to restore from backup C
    1.6 with ntbackup to restore from backup D
    1.7 Do I have at this moment also a working Exchange ?

    Second plan to recover (more time, more secure ?) :

    2.1 Boot with w2k3 CD to perform a w2k3 fresh installation
    2.2 dcpromo
    2.3 authoritative restore from backup B
    2.4 exchange fresh installation
    2.5 with ntbackup to recover from backup D

    What do you think about ?

    Thanks in advance.

    Re: ntbackup for DC

    An ASR is essentially a bare metal restore of a crash consistent state backup that should work assuming you have your floppy disk and a good backup set.

    No authoritative restore is necessary if this is the only DC in the domain.
