OpenAFS 2025-03-21 READ_TAPE(8)
Description
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 backup(8) command.
The dump files will be named for the Read/Write name of the volume restored. After saving each dump
file, vosrestore or restorevol can be used to restore the volume into AFS and non-AFS space
respectively.
read_tape reads the tape while skipping the specified number of volumes. After that, it restores the
specified number of volumes. read_tape doesn't rewind the tape so that it may be used multiple times in
succession.
Examples
The following command will read the third through fifth volumes from the tape device /dev/tape without
prompting:
% read_tape -tape /dev/tape -skip 2 -restore 3 -noask
