fwb's backup toolkit looks promising. http://www.fwb.com/cs/btk/main.html claims that you can incrementally mirror a disk, though it insists on the truly awful word 'evolutive' and doesn't actually mention preservation of symlinks.
there also appears to be a port of rsync with HFS+ support: http://www.macosxlabs.org/rsyncx/rsyncx.html if it wasn't a laptop, i'd be tempted to find out whether apple's built-in RAID support lets you mirror an ATA disk and a firewire one. there's nothing in the docs to say that you can't, and there shouldn't be that much of a performance penalty, given apple's less than cutting-edge IDE. but i suppose you want to be able to unplug the 'book at some point... best will ps. backing up work, fink, cvs repository manually here :( On Thursday, July 11, 2002, at 08:45 PM, Randal L.
