Dell PowerVault DR4100 - Manual (Page 18)

18 Setting up Dell™ DR Series Deduplication Appliance on VRanger Pro
• For Physical Machine
NOTE:
Always Disable ‘Check destination for free space’ as DR Series Deduplication Appliance supports
deduplication and so overall space occupied is lesser.
Always enable ABM (Active Block Mapping) for better overall results from both vRanger and DR.
vRanger recommends to Enable ‘Guest quiescing’ on VM backups, in case of backing up a
database (Eg : Exchange server).
Disable ‘compress backed up files’ for better savings.
