backup_status - Reports a Tape Coordinator’s status
backup status [-portoffset <TC port offset>] [-localauth]
[-cell <cell name>] [-help]
backup st [-p <TC port offset>] [-l] [-c <cell name>]
The backup status command displays which operation, if any, the
indicated Tape Coordinator is currently executing.
-portoffset <TC port offset>
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/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).
Prints the online help for this command. All other valid options
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
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
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
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
[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.
The Tape Coordinator has finished the operation.
The operation is waiting for the specified tape drive to become
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 "user.pat.backup":
% backup status -portoffset 4
Task 4001: Dump: 1520 Kbytes transferred, volume user.pat.backup
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.
