Chapter 6 Backing Up and Restoring

The GDS mirroring function secures data from disk failures by preserving replicas of data on multiple disks. However, the mirroring function is not capable of protecting data against accidental erasure by the user or data crash due to an application malfunction. In addition, data can be lost due to multiple disk breakdown or large-scale disaster. To recover data when these troubles occur, data back up is mandatory. Be sure to back up data on a regular basis.

This chapter discusses the operating procedures for backing up and restoring GDS volumes to provide useful information concerning operational design for backup and restore.
