I checked and this does a similar thing. You can use WG to punch out a connection, and I have before. The linked program uses quic in a similar way to WG but doesn’t do any of the routing, just registers the connection to a hostname for application level forwarding.

It looks more that it provides an easy setup for an alternative.

Both methods can work on cg-nat as well since you are punching out.

We have had success with this on port 443 and it appears to do a good job on networks that only allow browsing. Usual problems with TCP based VPN still apply.

Free ones are less common now (no-ip went paid.) Afraiddns is still free but requires regular account logins.

An easy option is to add the data folders for the container you are using as a volume mapped to a local folder. Then the container will just put the files there and you can backup the folder. Restore is just put the files back there, then make sure you set the same volume mapping so the container already sees them.

You can also use the same method to access the db directory for the migration. Typically for databases you want to make sure the container is stopped before doing anything with those files.
