Dell DR4000 - Manual (Page 14)

14 Setting up RDA Backup to Dell™ DR4x00 Disk Backup Appliance on Dell™ NetVault
with 32 bit plug-ins provide less performance than pass through back-ups. It is recommended to stick
to the default that DR chose to use rather than forcing the mode to be optimized even if the client has
more horse power. NVBU client running on a 64-bit Linux machine has 64-bit plugins.
1. On NVBU console, select Backup. On Selections tab, choose the dataset needs to be backed up.
2. On Backup Options tab, choose appropriate options.
