[afio.2.4.1/README:]
|
|
|
|
This is afio 2.4.1.
|
|
|
|
The current maintainer is Koen Holtman (koen@stack.nl).

Afio makes cpio-format archives. It deals somewhat gracefully with
|
|
input data corruption. Supports multi-volume archives during
|
|
interactive operation. Afio can make compressed archives that are
|
|
much safer than compressed tar or cpio archives. Afio is best used as
|
|
an `archive engine' in a backup script.
|
|

|
See the file SCRIPTS for more information on backup scripts that use
|
|
afio.
|
|
|
|
See the file PORTING for information on compiling afio on non-Linux
|
|
machines.

|
This afio version is based on a Linux port of afio 2.3. Since the
|
|
original port, significant functionality has been added and some bugs
|
|
were removed. While primarily intended for use under Linux, this code
|
|
should be portable to other UNIX versions. As far as I know, there
|
|
has been no afio development beyond 2.3 outside the Linux community.
|
|
Thus, it should be safe to advertise ports of this code to other UNIX
|
|
versions as ports of afio version 2.4.1.
|
|
|
|
---------------------------------------------------------------------------
|
|

|
Afio has far too many options and features (some of which are not even
|
|
in the manual page). Anything in afio that doesn't relate to reading
|
|
or writing an archive from/to a simple file or pipe or backing up and
|
|
restoring from floppies remains untested.
|
|
|
|
In particular, nobody has verified if the options -p -b -d -e -g -h
|
|
-j -l -m -u and -R and the special case archive names `!command'
|
|
and `system:file' really do what they claim to do.
|
|
|
|
Typical `tested' afio uses are
|
|
... | afio -o -v -f -b 1024 -s 1440x -F -Z /dev/fd0H1440
|
|
... | afio -o -v -s 1440k -F -V -Z -G1 /dev/fd0H1440
|
|
afio -oZvx /tmp/pipe1 </tmp/pipe2
|
|
afio -i -Z -k -v -x -n /tmp/pipe1
|
|
... | afio -s 512m -c 1024 -Z -T 20k -G 1 -E /backup/compressed -v -o \
|
|
-L /backup/LOG -z /dev/tape 2>/dev/tty8 >/var/adm/backup
|
|
|
|
WARNING1: The Linux floppy drivers below kernel version 1.1.54 do not
|
|
allow afio to find out if a floppy write error has happened. If you
|
|
are running a kernel below 1.1.54, afio will happily fail to backup to
|
|
(say) a write protected disk and not report anything wrong! The only
|
|
way to find out about write errors in this case is by watching the
|
|
kernel messages, or by switching on the verify option.
|
|
|
|
WARNING2: the code for -F (and -f and -K) is a complete mess. It will
|
|
probably work in the normal case, but don't expect it to handle a
|
|
write/verify error correctly. If you get such an error, best thing is
|
|
to restart afio completely.
