are performed on the Primary Filer,
then all the qtrees are transfered and
snapshotted on the Secondary Server
in a single operation.

greater than one per volume snapshotted with the VSS technology. Even
if a volume is snapshotted via several applications, only one instance is
guaranteed, whatever the value of TINA_APP_MAX_SNAP.
