Backup a large disk over several VTL in parralel

Hello,

i have a 35 TB disk that i need to backup and i can not split the job into several ones since it is 1 folder with a lot of files in it.

The backup type is a full backup and the window is 48 hrs (weekend). My backup is done over FC from the sotrage to my VTL using an NDMP server (i have 2 VTLs with several tapes under each VTL).

i need to optimize the backup to finish during this window; what options do i have? (i use deduplication already).

is it possible to write simultaneously to several VTLs using just 1 job?

Thank you
