Hi Walter,

Have a look at the Helpfiles for DIRT. Here is an excerpt;

Most Unity data is saved in this process. This includes all subscriber data, call handlers, interviewers, voice names, greetings, passwords, switch configuration information, etc. optionally you can backup report data and in the case of an Exchange based system, subscriber messages as well. Only a few specific items and settings are not preserved during the restore process.

From this most excellent DIRT Helpfiles link;

Hope this helps!
