interesting.
i did:

 mknod /dev/loop22 b 7 0
 dd of=/tmp/archive if=/dev/zero bs=1024 count=65536
 /sbin/losetup /dev/loop21 /tmp/archive
 mkdir /archive
 /sbin/mkfs /dev/loop22
 mount /dev/loop22 /archive
 cp -r /etc /archive
 unmount /archive
 cd /tmp
 gzip archive
 # it was just over a meg, gzipped
 # ftp'd it to another machine..
 # mknod'd, gunzipped, mounted
 
I knew it worked as emergency swap. but, backup could be a cinch.
I could make a set of backup files, one for each backup period.
operate on them as I would a standard partition, gzip and write 
them to tape or cd.

am I missing some important part of the equation? is there something wrong with
my logic, do people already do this kinda thing all the time? do people not do
it because of something I'm missing?
