backup_status - Reports a Tape Coordinator's status
backup status [-portoffset <TC port offset>] [-localauth] [-butc_noauth] [-cell <cell name>] [-config <configuration file>] [-help]
The backup status command displays which operation, if any, the indicated Tape Coordinator is currently executing.
Specifies the port offset number of the Tape Coordinator for which to report the status.
Constructs a server ticket using a key from the local /etc/yfs/server/KeyFileExt 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).
Assigns the unprivileged identity
anonymous to the issuer for all connections to Tape Controllers butc.
This option should only be used when the Tape Controller is incapable of authenticated connections.
Names the cell in which to run the command. Do not combine this argument with the -localauth flag. For more details, see backup(8).
Sets the location of the configuration file to be used. The default file is /etc/yfs/yfs-client.conf.
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>
Is a task identification number assigned by the Tape Coordinator. It begins with the Tape Coordinator's port offset number.
Identifies the operation the Tape Coordinator is performing, which is initiated by the indicated command:
The backup dump command.
The backup diskrestore, backup volrestore, or backup volsetrestore commands.
The backup labeltape command.
The backup scantape command.
The backup savedb command.
The backup restoredb command.
Indicates the job's current status in one of the following messages.
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.
For a running restore operation, indicates the number of kilobytes copied into AFS from a tape or a backup data file so far.
The backup kill command was issued, but the termination signal has yet to reach the Tape Coordinator.
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.
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.
The Tape Coordinator has finished the operation.
The operation is waiting for the specified tape drive to become free.
The Tape Coordinator is waiting for the backup operator to insert a tape in the drive.
If the Tape Coordinator is communicating with an XBSA server (a third-party backup utility that implements the Open Group's Backup Service API [XBSA]), the following message appears last in the output:
<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
% backup status -portoffset 4 Task 4001: Dump: 1520 Kbytes transferred, volume user.pat.backup
The issuer must be listed in the /etc/yfs/server/UserListExt file on every machine where the Backup Server is running, or must be logged onto a server with an account capable of reading the /etc/yfs/server/KeyFileExt file if the -localauth flag is included. =head1 SEE ALSO
