About configuration for EMC_TimeFinder_Snap
The EMC_TimeFinder_Snap method uses Symmetrix virtual devices (VDEV) to allow NetBackup to perform copy-on-write snapshot backups. This method does not require the establishment of a source-snapshot relationship between the primary and the VDEV devices before the backup. NetBackup automatically manages the source-snapshot relationship.
VDEV devices must already exist before they can be used in a NetBackup backup. Normally virtual devices are created by your EMC technical representative.
