Veritas NetBackup™ Bare Metal Restore™ Administrator's Guide

Mapping occurs as follows:

• Before the restore: You can create a configuration you can edit (an editable restore configuration) and initialize that configuration with the new disk layouts. Then map the original volume configuration to the new disks. After you finish mapping, you restore the client using the restore configuration.

  • Layouts of the new disks on the client, which is necessary, for example, when you perform a discovery operation.

  • Whether another protected client has the same disks.

• During the restore: You perform a standard restore and BMR detects that the disks are different. BMR enters DDR mode and creates an editable restore configuration so you can map the disks.

  • For UNIX and Linux clients, use the BMR disk mapping utility in the NetBackup Administration Console on the master server.

  • For Windows clients, you can map on the client during recovery or on the master server using the BMR disk mapping utility in the NetBackup Administration Console.

You should use dissimilar disk restore in the following circumstances:

• A physical disk is replaced.

• The size of one or more disks has decreased and cannot contain the same volume arrangement.

• The location of one or more disks changes.

• The number of disks has decreased and the required volume arrangement cannot be restored.

• You need to change the layout and volumes for the restored system.

• You want to restore only some of the disks in a system.
