About the deduplication license key
NetBackup deduplication is licensed separately from base NetBackup.
The NetBackup Deduplication Option license key enables both NetBackup Media
Server Deduplication and NetBackup Client Deduplication. The license is a
front-end capacity license. It is based on the size of the data to be backed up, not
on the size of the deduplicated data.
You may have a single license key that activates both NetBackup and optional
features. Alternatively, you may have one license key that activates NetBackup
and another key that activates deduplication.
If you remove the NetBackup Deduplication Option license key or if it expires,
you cannot create new deduplication disk pools. you also cannot create the storage
units that reference NetBackup deduplication pools.
NetBackup does not delete the disk pools or the storage units that reference the
disk pools. You can use them again if you enter a valid license key.
