BacPac's new disk duplication feature provides a way to make image copies of OpenVMS disks over a network between OpenVMS systems which are not clustered. This feature allows production system disks to be duplicated onto a backup computer system for rapid recovery from a production system failure. Switchover to the backup system is very fast because there is no need to wait for the disks to be restored from backup savesets. In addition to copying a disk, BacPac can also write a saveset at the same time so that a redundant backup of the disk is available.
