I currently use vSphere 4.1 (vcenter and ESXi) and Symantec backup exec 2010. Back up to normal when running. However the problem comes when restore vm. I did a restore vm-sized 600 GB. When the restore runs suddenly failed,failure was due to a database on sql express vcenter using full (more than 4 GB). Having traced during a restore runs 30-10% increase vcenter database of about 300 Mb.
Currently the problem is still unresolved. I am also going contact with Symantec if this is a bug in Symantec backup exec 2010 on vmware agent.
Please help with this problem.
