The same is true for patching the DTC server itself... What will happen if the DTC server gets updated and reboots while other clients are installing patches?  I'd like to hear how you all are handling it in your environment.

And finally, there the issue with backups.  After I migrated DTC to use SQL, I noticed a backup is still configured in the DTC console > Admin > Database Settings > Database Backup.  I do not see any way to turn it off.  We are already backing up the SQL server, so it would appear this local DTC backup is not needed.  What should we backup to be able to recover DTC and external SQL database?
