Description:  Recovers a backup catalog for the local computer from a storage 
location that you specify.
To use this command, you must be a member of the Backup Operators group 
or Administrators group. 

Parameters:
-backupTarget  Specifies the location of the backup catalog of the system as
                it was at the point after the backup was created.

-machine       Specifies the name of the computer that you want to recover
                the backup catalog for. Use when backups for multiple 
                computers have been stored at the same location. Should be 
                used when -backupTarget is specified.

-quiet         Runs the command with no prompts to the user.

WBADMIN RESTORE CATALOG -backupTarget:d:
WBADMIN RESTORE CATALOG -backupTarget:\\servername\share -machine:server01

Remarks:  If the location (disk, DVD, or remote shared folder) where you 
store your backups is damaged or lost and cannot be used to restore the 
backup catalog, use WBADMIN DELETE CATALOG to delete the corrupted catalog. 
In this case, you should create a new backup once your backup catalog is 
deleted.
