Chuckle. He he.  Since I am the one that last walked around in bru1.2, I 
don't have to look at its compression ratio, which is about -5% as it has 
no compression built in or callable and adds a sector per file for 
housekeeping.

The last (and only) time I backed up a hard drive with it, took me about 
2.5 evenings of feeding it 765k floppies, and the test recovery was over a 
week because it took on average, 35 minutes to read a 765k disk it could 
write in around 8 minutes, using an interleave of 8, the default of 3 took 
about 15 minutes to write because the disk had to go around 3 times in 
between sector writes.

However, if we had a really good compressor I could plug into bru with a 
pipe, the thought is tempting because from hard drive to hard drive, and 
enough compression to make that 90 megs fit in 40 megs, I wouldn't care how 
long it took either way because I wouldn't be super glued to this chair for 
days at a time feeding it floppies by the case.  That is terminally boring 
as you can well imagine.  Then what I would do is go to the garage and get 
a small ups, and put the coco on it so a power glitch wouldn't kill it in 
the middle.  That I should do anyway before that battery goes plumb away 
sitting on the umbrella table on the shops front deck.
