I'm testing it on openwrt version 19.07.4

What you need:

I'm running a backup of 40 GB through ssh for testing purpose.

It seems to work pretty well, so far I find two minor problems. from the log:

This rsync lacks old-style --compress due to its external zlib.  Try -zz.
Continuing without compression.

rsync seems to lack the --compress option

openwrt has dropbear for ssh by default which I don't think is compatible with some openssh options this script uses, still it ignores those options and works. (I'm trying with password, instead of ssh keys, since I'm on LAN)

from the log

ssh: Ignoring unknown configuration option 'StrictHostKeyChecking=no'
ssh: Ignoring unknown configuration option 'UserKnownHostsFile=/dev/null'

The minor problems where fixed by mounting the source destination before runnning the backup, instead of running rsync trough ssh. Also rsync --compression warning went away.
