Backup Microsoft Exchange

I do the NT backup of the exchange to a .bkf file, then rsync that file.  My
largest was about 12GB and it took about 1 hour and transferred about 300MB
of data across the net.  I had to use rsync 3.x to make this work, though.

You need to use shadow copies to create a drive you can use with rsync, or
you have to take Exchange offline.  You can use vshadow.exe (use version
3.0) to create the shadow copy and then expose it as a drive.  Then use
rsync to sync this point-in-time backup to your offsite location across an
ssh tunnel.  vshadow with the -w option means it will tell the Exchange
writer to create a consistent backup so you won't have problems with

There is plenty of documentation on how to use vshadow to expose a shadow
copy as a drive.  When using rsync to send it offsite be sure to use the -I
option since the date/time option of the exchange edb file will not
necessarily change.  

You can also use betest (VSS SDK) to truncate logs periodically and use the
-I option only when you truncate the logs.  The rest of the time you will
get the logs and you can do a soft recovery against your edb in the event of
a disaster.  If you truncate logs or use circular logging you have to use -I
to force a sync even if the date/time has not changed.
