exchange-2007

I have recently implemented Veeam backup and recovery 6.0, and have noted when backing up my exchange server via incremental updates, it is transferring way more data than expected.

Backup is incremental, and setup to use VSS.

VSS is stable and healthy, according to vssadmin.

Exchange 2007 SP3 running on Windows Server 2008 R2, just last weekend I installed the latest Rollup for Exchange.

I thought the nightly incrementals were large, but perhaps my users really are sending that much mail so I tested taking one incremental backup, waiting 10 minutes and taking a second. The second incremental backup transfered 5.8GB of data. We as an organization are absolutely NOT putting 5.8GB of data on the mail server every 10 minutes.

Are there any other veeam users who have seen something similar?

Is my test faulted?

Are there other considerations for VSS?
