snapshot size is difference between oncommand and netbackup

[YOKOMATSUMOTO]

Dear All,

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)
