What is the best and simplest way to back up the Unity System? In case the hard drive fails, can I restore users, call handlers, voice board configuration and recordings directly from the backup to a NT box with Exchange installed?<br><br>
The best way to backup a stand alone Unity server is to use an Exchange aware backup package such as BackupExec from Veritas. This will allow you to run periodic backups while Unity is up and running.
If you make a complete backup of your system including the Exchange server its a matter of restoring the NT system, rebooting, stopping the Exchange directory service, restoring the Exchange files and running a couple of Exchange tools to repair the directory (ISINTEG, MTACheck and the Consistency Checker). When you reboot the system should come back up as normal and be ready to roll.
Almost all of the dynamic information is stored in the Exchange directory so your Exchange backups will get most of the volatile information (messages, user information, call handler configuration and the like). The only thing stored on the local hard drive other than fairly static data such as your switch setup and call routing rules are the greetings. If you dont want to do full incremental backups of your whole hard drive all the time, youll want to at least snag the greetings directory.
If youre dealing with a Unity server installed into an existing Exchange site, youll want to work with whatever backup policies are in place on site, of course. Most folks in this environment will be using a decent remote backup server which should work fine. Again, youd want to make a complete backup of the NT box were on and then do periodic backups of the Exchange stuff using the tools on site.
Ive had folks ask about the built in NT backup that comes with Exchange. I dont recommend it. Anyone thats used it more than once can tell you its not the most robust tool out there (hence the reason it comes free with the system). You can certainly try it, but be prepared to be stranded in a worst case scenario.
