Hello all.
Allthough it probably isn't a tremendous memory saver, I couldn't
accept that busybox tar didn't function due to the problem with the
exclude files.
After a few changes to the /usr/sbin/lrcfg.back.script things are
working. I didn't find a problem with any of the packages I backed
up. For root I had to create a special case. (because of the root list
being (./ )
Tested with ash (from oxygen , linux 2.4.3 Busybox 0.50)
Look very carefully for changes in size at backing up !!
Smaller packets are mostly not more compressed but less
complete ; )
Changes to lrcfg.back.script.
