=head1 DESCRIPTION
The B<backup delhost> command deletes the indicated Tape Coordinator entry
from the Backup Database. It is then impossible to submit backup
operations to that Tape Coordinator, even if it is still running. To keep
configuration information consistent, also remove the corresponding entry
from the F</usr/afs/backup/tapeconfig> file on the Tape Coordinator
machine.
To list the Tape Coordinator machines and port offsets defined in the
Backup Database, issue the B<backup listhosts> command.
=head1 OPTIONS
=over 4
=item B<-tapehost> <I<tape machine name>>
Specifies the hostname of the machine housing the Tape Coordinator to
delete.
=item B<-portoffset> <I<TC port offset>>
Specifies the port offset number of the Tape Coordinator to delete. If
omitted, it defaults to C<0>. If provided, it is an integer between C<0>
(zero) and C<58510>, and must match the port offset number assigned to the
same combination of Tape Coordinator and tape device or file in the
F</usr/afs/backup/tapeconfig> file on the Tape Coordinator machine
indicated by the B<-tapehost> argument.
=item B<-localauth>
Constructs a server ticket using a key from the local
F</usr/afs/etc/KeyFile> file. The B<backup> command interpreter presents
it to the Backup Server, Volume Server and VL Server during mutual
authentication. Do not combine this flag with the B<-cell> argument. For
more details, see L<backup(8)>.
=item B<-cell> <I<cell name>>
Names the cell in which to run the command. Do not combine this argument
with the B<-localauth> flag. For more details, see L<backup(8)>.
=item B<-help>
Prints the online help for this command. All other valid options are
ignored.
=back
=head1 EXAMPLES
The following command deletes the Backup Database entry for the Tape
Coordinator with port offset 2 on the Tape Coordinator machine
C<backup3.example.com>:
% backup delhost -tapehost backup3.example.com -portoffset 2
=head1 PRIVILEGE REQUIRED
The issuer must be listed in the F</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 C<root> if the B<-localauth> flag is
included.
