how to troubleshoot slow vm backup
I m using netbackup 9.1 to backup vm.
All is running fine except the backup of a particuliar vm that is extremely slow.
the vmdk is 800Go size ans it take more than 12 hours to backup
i have CBT enabled , i have the accelerator enabled.
is there some way to improve the speed.
Here is the output of backup
