Wayne, Thanks for your reply. I upgraded to 2.6.8 and switched to --delete-during. But I still have the same problem as I did with --delete. I'll try to explain the behavior I'm seeing a little better. The directory I'm trying to rsync from has ~3.5 million files with the upper level directory having about 2000 directories. I'm running 'cd /backup/directory', then 'rsync -a --delete-during /backup/directory/directorytocopy .' on every directory in this top level directory. If I leave off the --delete-during (or --delete), everything works fine (except files removed from the original filesystem aren't deleted), but if I use the --delete-during option, I only end up with a small fraction of the original filesystem in my backup. It looks like it's only copying the changes to the original filesystem since the last rsync. I'm not 100% sure that this is what's happening though. The original filesystem has directories starting with a* to z*, but the resultant backup filesystem only has directories from m* to z*, so maybe it is deleting directories from earlier in the filesystem...I'm not sure. I have tried changing options in my backup script to get different behavior, but roughly the same thing happens every night when I run the script. How would you recommend running the rsync copy?
Also, after upgrading to 2.6.8, I tried copying the whole filesystem at once with 'cd /backup/directory; rsync -a --delete-during /production/filesystem/ .', but this gave me nothing in my backup filesystem.

You'd be better off using --del (--delete-during) than --delete, as it doesn't require a separate scan through the destination hierarchy. Also, older versions of rsync created an additional in-memory representation of the entire destination file tree to do the delete, so it is possible that such an older version caused rsync to start swapping, which could easily slow it down by an order of magnitude. So, make sure you're using a modern version (at least 2.6.4). As for any incorrect behavior of --delete, you'll need to be more explicit in what you think it is doing wrong. ..wayne.. -- To unsubscribe or change options: https://lists.samba.org/mailman/listinfo/rsync Before posting, read: http://www.catb.org/~esr/faqs/smart-questions.html
