NetBackup: Backing up individual EV Closed Partitions

Hello,

Is there any way to back up an individual Closed Partition in Enterprise Vault using Netbackup 7.5.0.4?

We don't want to do all of them, as they are close to 30TB and will just take too long/never finish.

Had a look through the NetBackup EV Admin guide and it only mentions ALL partitions.

Thanks in advance,
