I was wondering if it would be possible to add a switch (probably coupled to -v(+) ) that would report the number of matched blocks per file. Maybe even with the offset of the block. That of course wouldn't help much in a production environment, but it could help while setting up the whole backup strategy. This would have helped the original poster finding out if rsync is working correctly. bye Fabi -- To unsubscribe or change options: https://lists.samba.org/mailman/listinfo/rsync Before posting, read: http://www.catb.org/~esr/faqs/smart-questions.html
