About the MSDP license
NetBackup deduplication is licensed separately from base NetBackup.
The license 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.
If you remove the license 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.
The license also enables the feature on the NetBackup policy Attributes tab. Accelerator increases the speed of full backups for files systems. Accelerator works with deduplication storage units as well as with other storage units that do not require the deduplication option. More information about Accelerator is available.
See the NetBackup Administrator's Guide, Volume I:

Before you try to install or upgrade to a NetBackup version that supports deduplication, you should determine on which operating systems Veritas supports deduplication. See the NetBackup operating system compatibility list:
