It is common to find tarball/cpio scripts that archive modified files only. Transfering to the other server is the hardest choice. ftpcopy, rsyc and nfs are all options, but...
Perhaps the most secure option that requires no additional services/software is to use scp whch is basically ssh-based file-transfer. Just set up a key-based autheticated user (there are tons of OSX tutorials for ssh on the net) and in the script include the command for transfer.

Here are some posts to K12OSN. Can you comment on them or suggest the best solution for us. -- That is the 'manual' way to do it. Mondo automates the whole process very nicely. With Mondo, the system does daily incremental backups automatically. If your Server goes up in flames, simply purchase a new one, and re-install using the ISOs provided by the Mondo backup - voila! total restoration from cold steel. Very easy, and very quick. -- We use/like rdiff-backup for a similar scenario. rdiff-backup.stanford.edu -- Instead of just plain rsync (which is good), here is a better way to use rsync and not waste a lot of space. You get snapshots as often as you set it, and they are available to you read-only in a dated directory structure. I was real impressed with this one and will set this up for my server. http://www.mikerubel.org/computers/rsync_snapshots/ Abstract This document describes a method for generating automatic rotating "snapshot"-style backups on a Unix-based system, with specific examples drawn from the author's GNU/Linux experience. Snapshot backups are a feature of some high-end industrial file servers; they create the illusion of multiple, full backups per day without the space or processing overhead. All of the snapshots are read-only, and are accessible directly by users as special system directories. It is often possible to store several hours, days, and even weeks' worth of snapshots with slightly more than 2x storage. This method, while not as space-efficient as some of the proprietary technologies (which, using special copy-on-write filesystems, can operate on slightly more than 1x storage), makes use of only standard file utilities and the common rsync program, which is installed by default on most Linux distributions. Properly configured, the method can also protect against hard disk failure, root compromises, or even back up a network of heterogeneous desktops automatically. --Peter _______________________________________________ LUAU mailing list [EMAIL PROTECTED] http://videl.ics.hawaii.edu/mailman/listinfo/luau
