btrbk on Synology NAS

Hi,

I plan a big btrfs-based NAS.
1. I will use btrbk to send to a Synology but I also think about
2. running btrbk itself on such a platform.

Thinking about a self-maintened Linux machine vs. Synology. I plan to use such a btrfs also for sending my own snapshots to it, which might be possible on Synology via key-based SSH. Running btrbk on my own Linux workstation, sending to Synology should be solved by https://github.com/digint/btrbk/issues/383

I know that Synology has it's own snapshotting and retention stuff. This would apply to their own shared subvolumes, but maybe not for my own sent snapshots. So is it possible to run btrbk itself on such a platform and did somebody try?

No source file or test is named. Start by checking whether btrbk can run on Synology and whether its Btrfs and SSH requirements are available there; done would be a documented, reproducible compatibility answer.
