Backup and restore of Exchange Server 2007 + Win2k3 AD using disk Imaging tool.

Hi All,
I have a single box of Windows Server 2003 Std which act as my DC (4 FSMO role holder) and also Exchange Server 2007 (HT-CAS-MBx Server)

My current Exchange Server 2007 SP1 RU3 got problem in the autodiscovery error, however I'd like to perform a CAS role reinstall, here it is the things that I'd like to do:

0. Backup the whole server using Symantec Backup Exec System Recovery 8.5 (Full backup).
1. Go to Add/Remove Programs aand then do the Exchange Server 2007 - CAS Role only uninstall, then restart
2. Perform CAS role re-installation then restart again.
3. apply the .NET Fx 3.5 SP1 Update

my question questions are:
1. do i need to reapply the Rollup update 3 again or shall i just wait until RU 8 released ?
2. since this server also perform as my DC + FSMO role holder would it be fine if i use disk snapshot tool to do full backup and restore of my Server ?

for the fallback plan i shall just restore the backup image taken from step 0 above.
Please let me know if this is a good move or if there is any other formal method in doing it ?

Thanks

There should be no need for the re-installation of Update Rollup 3, as the rollup 3 version of the files should be used during the reinstallation of the CAS role.

Creating a disk image of the server is never a problem if you intend on restoring the full image if required. If you do, it simply rolls the server back to the point in time when the image was created. The problem comes when attempting to perform a partial restore from a disk image, as there will always be a particular file which is missed which will cause an issue with the roles installed in the system.

Matt,
Thanks for the reply, however I'm bit worries since my last full backup plan was not successful due to the AD communication between the following:
Server A - DNS + DC (Schema Master role)
Server B - Exc.Srv07 + DC (4 other FSMO role)
somehow didn't happened :-|, back then i was using Acronis True Image when restoring a working copy of my full backup of Server B.

From your original question it sounded as if you only had one server. A backup/restore of a disk image in that case would not be a problem.

Now Server A is involved, you may have problems with the Active Directory restoration if you try to restore Server B. If you will be doing this work off-hours, when no Active Directory changes will take place, my best solution would be to simply back up both servers; if you need to restore, you will have better chances of it being successful.

If the CAS role reinstallation does fail, it is unlikely you will need to resort to restoring a backup, as there are other approaches you can take in Exchange just to get the role playing again.

Yes, Sorry about that Matt,

Based on your suggestion I shall just do it off the office hour then in backing up Server B.
well, just in case bad things happen, i shall then backup Server A as well.
