About protecting the deduplicated data

Symantec recommends the following methods to protect the deduplicated backup

data and the deduplication database:

■ Use NetBackup optimized duplication to copy the images to another

deduplication node 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.

See “About MSDP optimized duplication within the same domain” on page 36.

See “Configuring optimized duplication of deduplicated data” on page 94.

■ For the primary deduplication storage, use a SAN volume with resilient storage

methodologies to replicate the data to a remote site. If the deduplication

database is on a different SAN volume, replicate that volume to the remote

site also.

The preceding methods help to make your data highly-available.

Also, you can use NetBackup to back up the deduplication storage server system

or program disks. If the disk on which NetBackup resides fails and you have to

replace it, you can use NetBackup to restore the media server.
