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
       /var/lib/openafs/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 /var/lib/openafs/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
       /var/lib/openafs/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 IBM AFS 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
           /etc/openafs/server/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 the backup(8) manpage.

       -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 the
           backup(8) manpage.

       -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 /etc/openafs/server/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.
