Using disk staging for your backup jobs can help avoid resource contention between backup operations and Vault duplication operations. Disk staging is the process of first writing the backup images to a disk storage unit during a NetBackup policy job and then writing the images to removable media during a Vault job.
Note: |
This topic is about using a disk storage unit as a destination for backup images, not about using a disk staging storage unit. |
Some of the advantages of disk staging over tape-to-tape duplication are as follows:
You can schedule your Vault sessions to duplicate the original disk backup images to two (or more) media: one on-site volume and one offsite volume. Also, you can configure the Vault profile to free up the disk space automatically for the next round of back ups.
