floppybackup - spread data read from stdin to multiple floppies
SYNOPSIS
floppybackup [options] [device] [archive_name]
DESCRIPTION
floppybackup reads data from stdin and outputs it to given floppy device. If no device is
given, "/dev/fd0" is assumed.
If no archive name is given, a name is created using the "date" program.
NOTE! If you don't give a device name, you can't give archive name either. This is
because the program parses args in a really stupid way.. the 1st arg with no
leading '-' is always
assumed to be the device, and the 2nd arg without a '-' the archive name.
A header is written in the beginning of each floppy, containing archive
name, disk number, whether or not the disk in question is last one in
archive, and how many bytes of input are stored on disk.
floppybackup can mix floppies of different sizes to create an archive. You
may use 720K, 360K, 1440K, 1992K or whatever floppy sizes your machine
autodetects.
The disks
MUST
be low-level formatted. Use "fdformat" or "superformat" to do that.
OPTIONS
"-q"
Print only errors and "Insert disk"-messages.
"-n"
Do
not
verify data that is written to floppies. Speeds things up somewhat, since
all data is assumed to be written without problems.
By default verify mode is
on
, and after writing a diskfull, the buffers are flushed and then a verify pass
starts. A temp file that gradually
increases in size is created. Its maximum size is that of the largest disk used in
the backup.
It is not recommended to turn verify mode off.
Nothing pisses one off more than finding out after a HD disaster that disk
3 of 99 total in an archive is broken.
