Backup Microsoft Exchange

[Steve Zemlicka]

Thanks Julian and Brad, I will give ntbackup a shot.  I've used
rsyncrypto but I'm not a huge fan.  I don't need the files to be
encrypted except during transit which can be done with just rsync,
right?

This should be simple:
Use ntbackup to create a large .bkf file at a scheduled time.
This will itself use shadow copy, so for this purpose (exchange) you
really 
don't need to get into the VSS SDK.

Moreover, I compress and encrypt that file with rsyncrypto (internally
pipes 
to gzip with the --rsyncable argument).
I end up with a file of around 8GB... (see http://rsyncrypto.lingnu.com)

This file takes around 45 mins to sync, but obviously it depends on the 
amount and types of changes you get between backups.
