VMware with granular backup

Hello All,

I have a question how Backup Exec creates a snapshot of a VM before backing up the VM.

I have VM with 4 hard disks.

-100 GB

-512 GB

150 GB

-150 GB

There are on 3 different data stores.

When Backup Exec creates the snapshot, is a snapshot taken of each disk before starting the backup process or does Backup Exec creates a snaphot of first disk, backup it and creates the next snapshot?

How about the additional space on the datastore needed for the snapshot. Will Backup Exec need the same amount of space for the snapshot as the disk space is?

Thanks,

Edy
