BACKUP_RESTOREDB(8)	     AFS Command Reference	   BACKUP_RESTOREDB(8)

NAME
       backup_restoredb - Restores a saved copy of the Backup Database

SYNOPSIS
       backup restoredb [-portoffset <TC port offset>]
	   [-localauth] [-cell <cell name>] [-help]

       backup res [-p <TC port offset>]
	   [-l] [-c <cell name>] [-h]

DESCRIPTION
       The backup restoredb command restores to the Backup Server machine's
       local disk a version of the Backup Database previously written to tape
       by using the backup savedb command.

       (If the "FILE YES" instruction appears in the
       /usr/afs/backup/CFG_device_name file associated with the specified port
       offset, then the backup restoredb command restores data from the backup
       data file listed for that port offset in the Tape Coordinator's
       /usr/afs/backup/tapeconfig file, instead of from tape. For the sake of
       clarity, the following text refers to tapes only, but the Backup System
       handles backup data files in much the same way.)

       The most common reason to run this command is to replace a corrupted or
       otherwise damaged Backup Database; use the backup dbverify command to
       determine the database's status. The command can also be used to
       restore records that were removed from the database when the -archive
       argument was included on a previous backup savedb command.

       The command completely overwrites the existing Backup Database records
       for volume sets, Tape Coordinators, and the dump hierarchy with the
       corresponding information from the saved version. It does not overwrite
       existing dump records, but instead interleaves the records from the
       copy being restored. If both the existing database (on the Backup
       Server machine's disk) and the copy being restored include a record
       about the same dump, the Backup System retains the one in the existing
       database.

       The Tape Coordinator's default response to this command is to access
       the first tape it needs by invoking the "MOUNT" instruction in the
       local /usr/afs/backup/CFG_device_name file, or by prompting the backup
       operator to insert the tape if there is no "MOUNT" instruction.
       However, if the "AUTOQUERY NO" instruction appears in the
       CFG_device_name file, or if the issuer of the butc command included the
       -noautoquery flag, the Tape Coordinator instead expects the tape to be
       in the device already. If it is not, or is the wrong tape, the Tape
       Coordinator invokes the "MOUNT" instruction or prompts the operator. It
       also invokes the "MOUNT" instruction or prompts for any additional
       tapes needed to complete the restore operation; the backup operator
       must arrange to provide them.

CAUTIONS
       If the database is corrupted, do not attempt to restore a saved
       database on top of it. Instead, use the instructions for repairing a
       corrupted database in the OpenAFS Administration Guide chapter about
       performing backup operations.

OPTIONS
       -portoffset <TC port offset>
	   Specifies the port offset number of the Tape Coordinator handling
	   the tapes for this operation.

       -localauth
	   Constructs a server ticket using a key from the local
	   /usr/afs/etc/KeyFile file. The backup command interpreter presents
	   it to the Backup Server, Volume Server and VL Server during mutual
	   authentication. Do not combine this flag with the -cell argument.
	   For more details, see backup(8).

       -cell <cell name>
	   Names the cell in which to run the command. Do not combine this
	   argument with the -localauth flag. For more details, see backup(8).

       -help
	   Prints the online help for this command. All other valid options
	   are ignored.

EXAMPLES
       The following example shows the Backup Database being restored from the
       Tape Coordinator with port offset 0:

	  % backup restoredb

PRIVILEGE REQUIRED
       The issuer must be listed in the /usr/afs/etc/UserList file on every
       machine where the Backup Server is running, or must be logged onto a
       server machine as the local superuser "root" if the -localauth flag is
       included.
