Restoring Data Using the DRScanSession Utility

The Disaster Recovery Option provides a special purpose utility, DRScanSession, that allows you to perform the following:

• Restore a system from a tape for which you do not have the latest disaster recovery machine-specific disk.
• Specify the backup from which a system should be restored. It may be necessary to specify this information if, for example, you want to restore a system from a previous full backup, not the last full backup. Additionally, this feature can help if, for example, you have misplaced the latest disaster recovery information. You can use this utility to specifically select the latest session from a tape as the session to restore the system.

To use the DRScanSession Utility, ensure that you have the following:

• A machine-specific recovery disk for the system you want to recover. It need not be the most recent one, but it should meet the following criteria:
  • The disk layout must be compatible in that, for each partition, the new volume should be larger than the old one.
  • The system configuration must be unchanged. For example, devices must not have been moved from one group to another and group names must be unchanged. In addition, no additional devices should be attached, and no new CA ARCserve Backup options added.

  Note: Disaster recovery information is updated each time you run a full backup.

• The tape and the tape session number of the disaster recovery session you want to restore.

Note: The Disaster Recovery DRScanSession Utility is supported for the Windows 2000, Windows XP, Windows 2003, and Windows 2008 disaster recovery process. It should not be used when recovering a system using the Bootable Tape method (OBDR).
