I have a Windows 2000 server running Exchange 5.5.  I'm backing it up
with NetBackup 3.4 to a Solaris 8.0 server.  The backups have been
running on this for a little while now; today I thought I'd check on
them and test the restore procedure (before I really need it).  To my
surprise, the "Select for Restore" browser under the Windows NetBackup
client doesn't have any way to look at or select from the Exchange
backups I'm making.  All it shows is the C: drive and registry backups
for the server.

By contrast, the "Select for Backup" browser for the client clearly
shows little icons for "Microsoft Exchange Server" and "Microsoft
Exchange Mailboxes".  I can either interactively kick off a backup of
these from the GUI, or they're able to be scheduled from the master
server.  In either case, the backups show up in the master's "Job
Monitor", and after several hours they complete successfully.

Both the client and my master server believe the backups are happening
correctly.  So... what stupid thing am I overlooking regarding the
restoration of this data?

Thanks for any pointers.
