The Ftape Installation Guide - zftape devices
/dev/zqft*
', `/dev/nzqft*
'Using zftape with these device nodes creates compressed volumes, using the lzrw3 compression algorithm (see Builtin Compression).
Note that the driver can read uncompressed volumes if used with the
compression devices `/dev/(n)zqft*
', but on the
contrary compressed volumes are treated as uncompressed when
the driver is used with the non-compression devices `/dev/(n)qft*
',
Thus one will get the raw compressed data and the header information.
Maybe useful for error recovery.
The driver can also read volumes that were produced by programs running under other operating systems and use the volume-table accordingly to the QIC-113 standard (http://www.qic.org), but then you will get the raw data that was written to tape, no uncompression, no extraction of files.
Also, tapes written by the original ftape-2.x are discovered. The driver switches to read-only mode so read access is still possible, including support for file-marks.
