I have a plan to create backup by SMVI and Netbackup.
The target volume is connected to ESX by iSCSI as a datastore, so I made a snapshot via SMVI.
My quiestion is , Oncommand System manager shows that snapshot size is 4.83GB
but on Netbackup much bigger size was written into tape.
It's big difference, which is correct and how can I estimate for backup of all virtual machines??
oncommand : 4.83GB
netbackup kilobytes written : 34040833(=roughly 32GB)
