Yes, of course, I want to use this doing remote transfers. But since I was not able to get it to work with our remote transfers, I was trying to do it locally to speed up testing. Are you saying that rsync knows the difference and will enable/disable delta transfers depending on whether local or not? However, again, I get the same result doing remote transfers. Thanks for the tip, I will try some more testing tomorrow using the --no-whole-file option... -- Robert -- To unsubscribe or change options: https://lists.samba.org/mailman/listinfo/rsync Before posting, read: http://www.catb.org/~esr/faqs/smart-questions.html
