If you’ve got a copy of the data that’s local, why are you opening up ports? Just run the backup job internally.

I'm often not at home for weeks at a time.

but man do I not trust a USB interface at all.

Trust?

I also recommend not relying on email for notifications - too unreliable. I use the healthchecks.io docker image and have it send me notifications via Pushover when something fails.

I'll look into this thanks!
