Deduplication Summary and Parameters settings

 

Just thinking what’s the best setting for deduplication for MSDP Pool .  My Netbackup appliance has a deduplication ration of 82.61% ? not totally sure what that’s means ?? ( See attached diagram )

Looking at the current default deduplication parameters attached, not sure what I can change to optimize my backups

Hi,

The ratio is dependent on the data you're backing up. Some data deduplicates better than others, Exchange vs SharePoint, Oracle vs mp3. You can't do much about it.

 

The 82.61% is the saving you got by using deduplication. If you didn't use dedupe, you would need more storage to have protected (backed up) everything you did.

 

1-0.8261 = 0.1739

1/0.1739 = 5.75 times more storage would be required.

 

The closer you get to 100% (which is not possible), the better.
