I am testing Veeam Backup on two ESX vCenter VM's. One, an Exchange 2007 server, is giving me trouble.
The server is 572GB. When I first ran the Replication job the VM summary screen reported that VSS Freeze failed to prepare. The job is running but the throughput is horrid, under 1 MB/s.

There is a termporary VM snapshot running on the Exchange VM. The Backup mode is service console agent.
The Storage is a Dell Equallogic SAN.
The destination ESX host is a DAS datastore.
At this rate it's going to take a long time to complete the first replication job. It's only done 5% in 7 hours...
Should I cancel this backup and try to determine the source of the problem or let the backup complete and then troubleshoot?

If I cancel the backup will this cause an issue with the Veeam snapshot on the VM?
