Rsync 2 also spent a long time building a list of changes files first, before transferring any data. Rsync 3 starts building the file list, then starts transferring data while it continues to build the file list. This drops the total time spent by a large factor. Our backup times dropped by about an hour per server switching from 2 to 3. Something else to consider when looking at resurrecting version 2. _______________________________________________ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-ports To unsubscribe, send any mail to "[email protected]"
