In theory, all you need to implement in the storage plugin is the
new_backup_provider() and parse_volname() methods and an empty/dummy
implementation for everything else. But you really don't need much else
to have proper integration as well, just listing backups, storage usage
status, etc. See the example plugins.

Easiest is to build a Debian package and provide that to your users.

You can use them to get an idea of how the implementation should look
like. Since communicating with your backup sever and your architecture
will look different from those basic examples, the concrete
implementation will most likely not be useful to you however.

Also, like other code in Proxmox VE, it is licensed under AGPLv3, so
copying non-trivial amounts of it means that copyleft needs to be respected.

Yes.
