Throughput Decreases on SAN Backups

Valid on Windows operating systems.

Symptom:

When you use VDDK to back up virtual machine data in SAN transport mode, the throughput decreases while the job is in progress.

Solution:

If you use VDDK to back up virtual machine data in SAN transport mode and the throughput decreases while the job is in progress, do the following:

1. Delete or rename the following directory on the backup proxy system:

   C:\Documents and Settings\Administrator\Local Settings\Temp\vmware-<<username>>
   

   Example:

   C:\Documents and Settings\Administrator\Local Settings\Temp\vmware-Administrator\vmware-administrator
   

2. Resubmit the job.
