DESCRIPTION
ftio is a tool designed specifically for copying files to tape drives. It performs faster than either
cpio
or tar in comparable situations (see cpio (1) and tar(1)).
ftio uses multiple processes (to read/write
the file system and to write/read the tape device), with large amounts of memory sharing between
processes as well as a large block size for reading and writing to the tape.
ftio is compatible with cpio in that output from cpio is always readable by ftio, and output from
ftio is readable by cpio, except as explained in the "cpio Compatibility" section, later in the manpage.
ftio must be invoked with exactly one of the following options: -o, -O, -i
, -I,or-g. The -o and -O
options specify that ftio is writing "out" from file system to tape; the
-i and -I options specify that
ftio is writing "in" from tape to file system. The -o,
-O, -i, and -I options can be followed by
modifiers that must appear immediately after the option with no spaces between the option and the
modifier, as in
ftio -idxE (see Modifiers section below).
tapedev specifies the name of a device special file for the tape device to which the output is written. A
device on a remote machine can be specified in the form
machine
:device_special_file
ftio creates a server process from /usr/sbin/rmt
on the remote machine to access the tape device.
If
/usr/sbin/rmt does not exist on the remote system,
ftio creates a server process from
/etc/rmt, on the remote machine to access the tape device.
Options
ftio recognizes the following options:
-o Copy (out) files from the file system to tapedev , including path name and status
information. If pathnames are specified, ftio recursively descends pathnames
looking for files, and copies those files to tapedev .Ifpathnames are not specified,
ftio reads the standard input to obtain a list of path names to copy. ftio can
copy to multiple tapes if required. For every tape used, ftio generates a tape
header containing the current tape volume number, machine node name and type,
operating system name, release and version numbers (all from the uname() sys-
tem call; see uname(2)), username of the person issuing the ftio command, the
time and date the command was executed, the number of consecutive times the
current media has been used, a comment field, and other items used internally by
ftio. The tape header is separated from the main body of the tape archive by an
end-of-file mark. The tape header can be read by invoking cat with the device file
name as the first argument (see cat (1)). Note, character and block device special
files written with the -o option are not transportable to other HP-UX implementa-
tions.
-O Copy out files in the same way as ftio -ocva, when no modifiers are used with
the -O. However, if the .ftiorc file exists in the user’s home directory, ftio
opens this file and scans for lines preceded by O=. Options defined on matching
lines are passed to ftio as if they had been specified on the command line. See
EXAMPLES section.
-i Extract (copy into the file system) files from tapedev , which is assumed to be a tape
and the product of a previous ftio -o operation. Only files with names that
match patterns , according to the rules of Pattern Matching Notation (see regexp (5)),
are selected. In addition, a leading ! within a pattern indicates that only those
