There have been questions about backing up Mac OSX Tiger 10.4 file systems with dirvish and rsync. This is complicated by the way UFS works. It is probably not un-solvable, but to date it has not been solved, and solutions will require modifications to rsync and maybe to OSX.
For more information, watch the mailing lists for rsync: http://samba.anu.edu.au/rsync/lists.html And also the Mac OS-X server mailing list: http://lists.apple.com/mailman/listinfo/macos-x-server There is a discussion of backup going on right now on the Mac list; changes to 10.4 are breaking many common Mac backup tools, not just rsync. When Wayne Davidson's mainline rsync is modified to handle the intricacies of 10.4 UFS+, we may need to make modifications to dirvish to handle those modifications. It may be possible to do backups on UFS+ with the existing version of rsync and some extra cleverness, but at this time nobody on either of the above lists has contributed a solution. Sometimes the operating system does not even permit a complete backup solution - rsync has this problem with Windows XP, though some clever people have developed workarounds. Even on Linux, the way the OS handles symbolic links does not permit dates and times to be restored with rsync. Many of these problems can only be fixed by adding to the operating system, and that will be difficult for proprietary operating systems. Dirvish is a wrapper around rsync, which in turn depends on the API provided by the operating system underneath. If rsync or the API are inadequate, there is not much we can do to dirvish to work around that. I would really like to see solutions, I want to back up a 10.4 system too. Not yet. :-( Keith -- Keith Lofstrom [EMAIL PROTECTED] Voice (503)-520-1993 KLIC --- Keith Lofstrom Integrated Circuits --- "Your Ideas in Silicon" Design Contracting in Bipolar and CMOS - Analog, Digital, and Scan ICs _______________________________________________ Dirvish mailing list [email protected] http://www.dirvish.org/mailman/listinfo/dirvish
