Glad to hear you worked it out, and sorry you wasted an hour on this! If either of you have suggestions for what would have been helpful in the documentation to avoid this sort of problem, please let me know. I'm guessing that the relevant section is here: https://torsion.org/borgmatic/docs/how-to/set-up-backups/#autopilot .. Thanks.

Thanks for reporting this! My guess is that systemd is not running borgmatic as the correct user, and therefore you're getting permission denied. Assuming that you want to run borgmatic as root, can you try something like this in your service file?
