Description:
This article explains the NDMP connections limitation.

There is no limit to the number of NDMP connections you can have running at the same time, as long as NetVault is configured correctly within the NDMP Backup Options.
The option 'Number of backups to run in parallel' found in the NDMP Backup Options tab is set to 0 by default.
The value should be equal to the number of drives +1.
