I am running exchange server 5.5 sp3 on NT 4.0 sp3. I currently have no tape backup and wish to install it. As I understand it, when exchange is installed, mods are made to the nt backup program to allow exchange partitions to be backed up. Is this true? Will I need 3rd party software to do a reliable backup of exchange?<br><br>If I install an hp superstor t20xi, will it do the job? Is this device compatible with NT? The MS HCL says no, the HP list says the t20xe is compatible and the tech rep at hp says the t20xi is compatible even though it is not listed.!!<br><br>Does anyone have any guidlines that I could follow to insure that I get what I think I will be getting in backup?<br><br>Thanks.
