Of course --no-whole-file will make rsync report a smaller number of "bytes sent", but is it actually reducing the amount of I/O to the mapped drive? If so, I find this really surprising. The one explanation I can think of is that the network filesystem has cached the file, so reading the basis file costs nothing and writing only the changed areas (due to --inplace) is a big saving. Is this the case? Matt -- To unsubscribe or change options: https://lists.samba.org/mailman/listinfo/rsync Before posting, read: http://www.catb.org/~esr/faqs/smart-questions.html
