Migrating from another storage type to deduplication

To migrate from another NetBackup storage type to deduplication storage, Symantec recommends that you age the backup images on the other storage until they expire. Symantec recommends that you age the backup images if you migrate from disk storage or tape storage.

You should not use the same disk storage for NetBackup deduplication while you use it for other storage such as AdvancedDisk, BasicDisk, or SharedDisk. Each type manages the storage differently and each requires exclusive use of the storage. Also, the NetBackup Deduplication Engine cannot read the backup images that another NetBackup storage type created. Therefore, you should age the data so it expires before you repurpose the storage hardware. Until that data expires, two storage destinations exist: the media server deduplication pool and the other storage. After the images on the other storage expire and are deleted, you can repurpose it for other storage needs.
