Public bug reported: I am using rsync for many years for various backup scenarios. One backup goes from my KUbuntu 15.10 ext4 hard disk to a (Windos) ntfs share.
With rsync 3.0.9 from Ubuntu Precise this was a very fast and comfortable task. Since rsync version 3.1.0 everything is extremely slow. So I tried many things from removing (-a -z ...) to adding (-W --modify-window=1 --inplace ...) rsync options, but no avail. There is also no difference if the synchronization is via network or USB. With other ext4 hard disks everything is just fine, as always. I wasted a lot of time searching, but the culprit is rsync 3.1 alone. Today I installed the old rsync version 3.0.9 from Ubuntu Precise and voilà rsync is working again. I do not understand why you provide a broken package and why it is broken for so many years. Or does nobody else use rsync between ext4 and ntfs? ** Affects: rsync (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to rsync in Ubuntu. https://bugs.launchpad.net/bugs/1524703 Title: Rsync 3.1 is extremely slow (ext4 » ntfs) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/rsync/+bug/1524703/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
