|-portoffset <TC port offset>||Specifies the port offset number of the Tape Coordinator for which to report the status.|
|-localauth||Constructs a server ticket using a key from the local /usr/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 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.|
The following message indicates that the Tape Coordinator is not currently performing an operation:
Tape coordinator is idle
Otherwise, the output includes a message of the following format for each running or pending operation:
Task <task_ID>: <operation>: <status>
If the Tape Coordinator is communicating with an XBSA server (a third-party backup utility that implements the Open Groups Backup Service API [XBSA]), the following message appears last in the output:
<task_ID> Is a task identification number assigned by the Tape Coordinator. It begins with the Tape Coordinators port offset number. <operation> Identifies the operation the Tape Coordinator is performing, which is initiated by the indicated command:
Dump The backup dump command. Restore The backup diskrestore, backup volrestore, or backup volsetrestore commands. Labeltape The backup labeltape command. Scantape The backup scantape command. SaveDb The backup savedb command. RestoreDb The backup restoredb command. <status> Indicates the jobs current status in one of the following messages.
number Kbytes transferred, volume volume_name For a running dump operation, indicates the number of kilobytes copied to tape or a backup data file so far, and the volume currently being dumped. number Kbytes, restore.volume For a running restore operation, indicates the number of kilobytes copied into AFS from a tape or a backup data file so far. [abort requested] The backup kill command was issued, but the termination signal has yet to reach the Tape Coordinator. [abort sent] The operation is canceled by the backup kill command. Once the Backup System removes an operation from the queue or stops it from running, it no longer appears at all in the output from the command. [butc contact lost] The backup command interpreter cannot reach the Tape Coordinator. The message can mean either that the Tape Coordinator handling the operation was terminated or failed while the operation was running, or that the connection to the Tape Coordinator timed out. [done] The Tape Coordinator has finished the operation. [drive wait] The operation is waiting for the specified tape drive to become free. [operator wait] The Tape Coordinator is waiting for the backup operator to insert a tape in the drive.
<XBSA_program> Tape coordinator
where <XBSA_program> is the name of the XBSA-compliant program.
The following example shows that the Tape Coordinator with port offset 4 has so far dumped about 1.5 MB of data for the current dump operation, and is currently dumping the volume named user.pat.backup:
% backup status -portoffset 4 Task 4001: Dump: 1520 Kbytes transferred, volume user.pat.backup
The issuer must be listed in the /usr/local/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.
