-
- I don't think files in *nices are stored in such a way as that would be
- possible - I may be wrong, but mtools should be reading the file allocation
- table off of a DOS floppy and using that info to display a directory. To
- grab a file, it can go to the location on disk specified by the FAT entry.
-
- There isn't a FAT per se in *nix, is there? Just a bunch of inodes? Okay,
- someone else field this one ;^) because I'm quickly leaving my element of
- "end-user" and "programmer" and creeping towards "OS hacker" -- help!
-
- But aside from that, I don't see why you couldn't just do:
-
- fdformat
- mkfs -c /dev/fd0 1200 (or 1440 for a 1.44mb 3.5")
- mount /dev/fd0 /linux.floppy
- tar cvf /linux.floppy/my.tar *
- umount /dev/fd0
- ...and take it with you...
-
- (of course you can skip the fdformat and mkfs step if the disk already
- has a file system on it)
-
- Also, on my Sparc at work I have used other programs similar to tar, one
- which springs to mind is called 'bar' -- I seem to remember this utility
- would let you put multiple 'bar'chive files onto a single floppy or tape.
-
- The man page wasn't enough to refresh my memory (it's been a long time
- since I backed up my files on disk! Exabytes work great) on how to use
- it or specifically what it can do better, but I know a "bar" file isn't
- compatible with a tar file. Multiple tar archives can be put inside
- multiple bar archives on one disk, tho, which makes it a bit better than
- tar for disk backups (multiple volumes)
