Backup Speed with VCB and BackupExec

[crazex]

Now that I've managed to get the BEIM for VCB working, I am wondering why is my backup speed so slow?

When I process my backup jobs via Backup Exec, I am using the BEIM to make snapshots, and mount them to a SAN LUN on my VCB proxy, but the write to tape is only in the 250-450MB/min range. The tape library is a Dell TL4000 with a native fibre connection. We are using Qlogic 4GB switches for our fabric. When I run an esxRanger backup, whereas, the backup makes a local copy to the volume, and then moves it to tape, I am seeing speeds in the 4000-5000MB/min range. Any idea on why the VCB jobs get written so slowly? All the SAN/Tape/Proxy zoning is working properly. I am currently using a single path, as this is just for testing.

We decided to try VCB but were highly disappointed with the results.

The road we went down was to put our VM's on NFS and utilize out regular backup prodedure. Backup times are better than anything we have ever seen till now.
