Recovery Utilities (1)Reset Backup and Restore Fail Recovery starts depending on the ETERNUS DX system status
• Status "Backup Fail" occurs on an ETERNUS DX system that cannot start up because an error occurred during a power failure or while turning off
• Status "Restore Fail" occurs on an ETERNUS DX system that cannot start up because an error occurred while turning power on

Recovery Utilities (3)Force Restore Forcibly restore cached user data that was backed up from the cache to
the BUD during a mains power failure• If for example the ETERNUS DX has status "Not Ready", the user data on BUD
will not be restored automatically to the cache when mains power is restored
