Appendix D - Disaster Recovery; Disaster Recovery Concepts - HP BB118BV - StorageWorks Data Protector Express Package User Manual

Bare Metal Disaster Recovery is a Data Protector Express agent that performs disaster recovery
operations as automatically as possible during initial preparation and recovery. It allows you to create
bootable media which you use to recover your system configuration, software and data following a
system or disk failure. The extent of automation varies according to your system. For example, if you
have a tape drive that supports One-Button Disaster Recovery, bootable media is automatically created
when you run your backup job. Other systems require you to create bootable media as a separate step
after running your backup job.

Disaster Recovery (DR) operates without the benefit of the Data Protector Express catalog. When it
restores data it restores the entire contents of each media provided. The media can be supplied in any
order but if there are incremental or differential backups on the media set along with the full backup,
objects will be restored in the order they are found on media and the results may not contain the most
current versions of the backed-up data.
: DR does not currently support split spanning of objects. Any objects that are split spanned on the
backup media will not be restorable during the DR process but must be restored after the DR process has
completed. If the split objects are critical to the functioning of the system, your system may not function
after the recovery process. Since there is not an easy way to know which objects are split across media, it
is best to not use the default, restarts spanning mode, when creating a DR backup.
Some data requires that a system service be running to successfully recover it. Those objects are skipped
during the DR restore process and must be restored in a separate restore job once disaster recovery is
complete.
DR recovers: directories, files, Windows Registry files, volume quotas, windows event log, the Data
Protector Express catalog, linux character and block special devices, linux FIFOs, symbolic links, linux
sockets, and mount points. All other objects must be restored separately (most notably: the remainder of
Windows System State needs to be restored).
