OTOH I found running rsync daily over the Internet to backup a Linux box impractical; it used heaps of RAM (and swap) and ran for hours. Fortunately, its excessive use of swap (several times real RAM) didn't lead to thrashing. Now, I run a hand-crafted script that makes a compressed ISO (mkzftree) and I rsync that. I'm maintaining a backup filesystem of about 8 Mbytes remotely now; the rsync runs for a little over two hours daily. -- Cheers John -- spambait 1aaaaaaa at coco.merseine.nu Z1aaaaaaa at coco.merseine.nu Please do not reply off-list
