My guess is it's the out-of-date rsync that ships with macOS, and I think
there may be other oddities with the macOS version. The version I built
from source is 3.1.3 and it seems to work fine. I have it in /usr/local/bin
which is earlier in $PATH than /usr/bin.

Glad to know you got it working. Any reason you don't want to use rsync?
IIRC I built rsync from source because of the issues with the version that
ships with macOS.

With the rsync transfer method, checksums are computed on the hosts and
duplicate files are not transferred. Not sure about the exact sequence with
other transfer methods.

You can change the configuration per host, including how older backups are

According to the man pages, the ConnectTimeout and ServerAlive settings
only apply to ssh_config, i.e. the BPC end, whereas the other settings only
apply to sshd_config, i.e. the host you are trying to backup.

And what do you have set for timeout - is it 600 seconds? Or perhaps the
