This arrangement strikes me as very awkward. For one thing, you don't get the benefit of incremental transfer. I can see how permissions on U: would get mangled in rsync to Cygwin to Windows to Samba (I'm guessing) to Linux conversion, causing U: to ignore rsync's attempt to set the permissions from the source on it. That means the permissions differ every time, so rsync doesn't try to hard link files, but even if it did, hard linking is unlikely to work through layers of Cygwin, Windows, and Samba. As a workaround, don't preserve permissions. You clearly tried to preserve everything except permissions, but keep in mind that -a, your first short option, includes -p. Delete the a: "-rltgoDvzi". I would also recommend not preserving user and group ownership. This should get rid of the itemized differences, but rsync is still likely to fail to hard link identical files. A better solution would be to have the Windows machine push the files to an rsync daemon running on the Linux server. However, rsnapshot only supports local snapshot roots, so you would have write your own script to invoke rsync. This isn't so bad. Just come up with a name for the destination directory and use --link-dest to link to the previous one. To set up an rsync daemon, write a configuration file according to the instructions in rsyncd.conf(5), and then invoke the daemon using rsync --daemon --config=<the-file>. This strategy will give you incremental transfer and hard linking, and you can safely tell rsync to preserve permissions. Nonetheless, the permissions rsync reads through Cygwin won't meaningfully represent Windows permissions. -- Matt McCutchen [EMAIL PROTECTED] http://hashproduct.metaesthetics.net/ -- To unsubscribe or change options: https://lists.samba.org/mailman/listinfo/rsync Before posting, read: http://www.catb.org/~esr/faqs/smart-questions.html
