Cohesity recommends the following methods to protect the deduplicated backup data:

• Use NetBackup optimized duplication to copy the images to another deduplication node at an off-site location.

  Optimized duplication copies the primary backup data to another deduplication pool. It provides the easiest, most efficient method to copy data off-site yet remain in the same NetBackup domain. You then can recover from a disaster that destroys the storage on which the primary copies reside by retrieving images from the other deduplication pool.

• Use NetBackup replication to copy the deduplicated data to another NetBackup domain off-site.
