Package: rsync Version: 3.1.2-2 Severity: important Tags: upstream If the destination of an rsync transfer is not writeable or runs out of free space, the transfer does not abort. Instead, even the next file is happily processed and errors are delayed until the very end:

rsync error: some files/attrs were not transferred (see previous errors)
(code 23) at main.c(1196) [sender=3.1.2]
There, 2G of data transferred pointlessly. Or this:
% rsync -Pvr /tmp/rsynctest/ /mnt

rsync: write failed on "/mnt/one": No space left on device (28)
rsync error: error in file IO (code 11) at receiver.c(393) [receiver=3.1.2]
And here, 1G of data transferred pointlessly.
This hasn't exactly caused data loss, but certainly a lot of time
was wasted.
