You could buy a real product that does this...
Netapp filers, along with their snap manager for exchange, gives you the ability to snapshot the exchange database, run eseutil on the snapshot to verify it, and then replicate to a remote netapp filer using their snap mirror product. We us them in a number number of locations with Iscsi luns for the exchange database and logs, and we are very happy with it.

Given the zfs snaps on the copy side, it's pretty bloody cool, if I need more retention I just add to the pool. Given the unsupported nature, I only did this at home with my stuff for some time, but since my home and work is all virtualized, verifying backups is *almost* no pain at all. I thought about using rCLI or ssh commands to start the "lab" and run a verify then shut off and rollback, problem is I don't really know an automated way to check the backup except for event logs/eseutil? To get the data in the segmented lan I plan to just mirror the DB's to an iSCSI lun so it can be mounted from any server and brought up to date. Bah next time when I am even to bored to do nothing:) jlc -----Original Message----- From: Harry Singh [mailto:hbo...@gmail.com] Sent: Wednesday, July 08, 2009 6:07 PM To: MS-Exchange Admin Issues Subject: Re: Backup generations VSS snapshots have the ability to merge differences/deltas in an exchange mdb and log file, respectively? I remember differentials being only as good as the last full, but if VSS can merge deltas into the original mdb, that must conserve a significant throughput strain. On 7/8/09, Joseph L.
