NetBackup Bare Metal Restore™ Solution Overview
• NetBackup is the first enterprise backup solution that has an integrated bare
metal recovery option capable of making use of ordinary backup data to
automatically restore a system.
• The system being restored does not need an Operating System installed on
the disk drives.
• The BMR option will allow NetBackup to restore a system to the exact
configuration that existed at any point in time for which a valid backup image
exists – either full or incremental, including synthetic backups.
• The BMR option allows the recovery of Windows Systems to completely
different hardware.
