We're considering various methods to backup Macintosh hard disks using our UNIX systems. We've looked at "macdump" but do not feel we can use it due to it's lack of security. This is sad, as it's a near perfect solution for what we need. What we're looking for now is some method of copying an arbitrary directory tree to another location. This method should notice changes (like DiskFit) and only copy the changes. We've tried a number of the public domain disk backup programs, none of which seem to work when using AUFS. Also, diskfit and SUMII's backup functions don't work on AUFS volumes. Does any one have a good way to do this that is secure? Session level security (ie. login & passwd per backup/restore) would be sufficient. --Dwight D.

I am not sure exactly how macdump works, but I know that I have been working on an _application_ that sounds similar. It was designed for educational institutions that have students using the hard disks durnig the course of a class and subsequently making a mess out of them. It is basically an incremental backup program that copies from one mounted volume to another. It has the capability to go to and/or from a specific node on a directory tree. It is something that must be done explicitly (i.e. you must somehow launch the program manually), but it is very automatic once started, cause it remembers the names of the source and destination volumes, can be set to automatically start the copy process on launch, quit after completion, and if desired, shut down the power on mac IIs. I talked about starting it a few months ago, version .61 is the one that actually works correctly. (There was a small bug in the string comparison routine on earlier versions). I thought it would have come across comp.binaries.mac by now, but I guess there is something of a backlog for sub missions, so if you want a copy of it, I can send you a binhexed version of it thru netmail. If you require the node to node version, please state so in your request. Be forewarned that it may not come as quickly as I have not worked out the user interface issues on it yet.
