15 Setting up RDA Backup to Dell™ DR4x00 Disk Backup Appliance on Dell™ NetVault
NOTE: Before doing any Incremental/Differential backup, make sure you have a Full backup run
with same ‘Backup Selection Set’.
NOTE: NVBU’s “consolidated incremental plugin” might not be very efficient with RDA device, as
optimized synthetic backups are not yet supported with NVBU RDA. This works functionally, but
performance might suffer.
3. On Schedule tab, configure the backup job schedule.
