I am happy to share my Balena “samba-rsync” Application (github link).
This application consists of a single docker container “samba-rsync”
which allows to take backups of windows shares (samba) to an external harddisk using rsync.
For more information I recommend to read the readme
@janvda would you consider tagging your GitHub repo with balena and balenacloud? We’re hoping to make it easier for other users to find useful projects like this one
