=head1 DESCRIPTION
|
|
|
|
|
|
|
|
|
|
B<read_tape> reads an OpenAFS backup tape and prompts for each dump file to
|
|
|
|
|
save. This command does not require any OpenAFS infrastructure. This
|
|
|
|
|
command does not need an OpenAFS client or server to be available, which is
|
|
|
|
|
not the case with the L<backup(8)> command.
|
|
|
|
|
|
|
|
|
|
The dump files will be named for the Read/Write name of the volume restored.
|
|
|
|
|
After saving each dump file, B<vos restore> or B<restorevol> can be used to
|
|
|
|
|
restore the volume into AFS and non-AFS space respectively.
|
|
|
|
|
|
|
|
|
|
B<read_tape> reads the tape while skipping the specified number of volumes.
|
|
|
|
|
After that, it restores the specified number of volumes. B<read_tape>
|
|
|
|
|
doesn't rewind the tape so that it may be used multiple times in succession.
