Backup Exec 2012 - DataDomain VTL - Slow Performance

Hi,

We recently have configured Backup Exec 2012 with Data Domain VTL to backup our VMware virtual infrastructure. 

Here is berif description how we setup our backups.

- Backup Exec server is zoned with DD and Storage.

- all VMFS volumes are visible to BE server to backup over SAN

- 50 VTL drives are visible to BE server.

-BE server is fully patched.

on running backup we observe 5000-9000 MB/min. and our backup size is like 12TB.

any idea to improve performance.
