- Well, you could just run "tar cvf /dev/fd0 /" (more or less) if you're
- using GNU tar. GNU tar has multivolume support built in, so it will ask
- you to change floppies as appropriate. But it won't compress the data
- and do multiple volumes at the same time, which means you need
- perhaps twice as many floppies. Also if your tar isn't the GNU version
- (like if it's linked to pax) this won't work.
- Most people use a wrapper around tar to allow compression and to
- add some user-friendliness. The three I know of are shown below,

- Backflops was written by me, so of course it's what I recommend.
- It certainly has more bells and whistles than the others, but take
- a look at all of them. Floptools is simply a couple of scripts;
- it's the lightweight solution. Diskbackup is a somewhat more
- ambitious C program, and backflops is also in C and attempts to
- overcome some of the limitations of the other two. It should work
- with pax-tar, though I haven't tried it.
- I think lots of other people have their private solutions but haven't
- made them public. Feel free to ask me directly if you have questions
- about backflops. Good luck.
