Bare Metal Disaster Recovery (DR) 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.
If you create a full backup to any removable device that supports bootable media, that media will
be bootable and can be used for bare-metal recovery. Devices that support bootable media include
removable cartridge disk drives, any external disk drive connected via USB or Firewire, and any tape
drive that supports One-Button Disaster Recovery (OBDR). If you use other backup devices, you must
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.
Data Protector Express do not support the Disaster Recovery feature. If your edition does not support
Disaster Recovery, any job that attempts to use the feature will report that the feature is not licensed.
If you need this feature, contact your reseller to purchase an edition of Data Protector Express that
supports Disaster Recovery.
NOTE:
You will only be able to perform bare-metal recovery to the same or an nearly-identical computer.
Bootable devices
Backup devices that support bootable media and bare-metal recovery include ...
• removable cartridge disk drives and
• tape drives that support One-Button Disaster Recovery.
Your computer must be able to boot from a device before it can be used for disaster recovery. Please
refer to the computer manufacturer’s documentation on how to boot from a removable device.
One-Button Disaster Recovery (OBDR) is a firmware feature that is supported on some tape drives which
enables the tape drive to act like a bootable CD-ROM when it is put into Disaster Recovery mode. When
you create a full backup on an OBDR tape drive, Data Protector Express product automatically makes the
media bootable. When you run One-Button Disaster Recovery, (normally by a combination of power
