If someone were aiming at a backup in minumum time vs. minimum space,
they might lear from a product calle "FastBack" intended to backup to
floppies. It had three modes, min time, min space, and "keep up" (by
some catchy name). The last is of some interest, since the compression
and CPU needed was adjusted during the backup.
It turns out the gzip handles this nicely. You can gzip a file with one
setting, gzip another and concatenate it on the end of the first, etc,
then zcat the whole thing. I have some huge logs which I compress and
append every eight hours, although I use the same setting for all.
So it would be possible to read in blocks and compress more or less
based on what's in a program internal buffer to send to the CD.
This is a musing only, you wouldn't do it in shell unless it was the
only thing you had, and it would be nasty to implement, so it's just
food for thought.
Thank you for the review.
