By default, the Synology DSM "btrfs send" command outputs ACL attributes that are not compatible with a normal Btrfs implementation. The option compat "synology" allows passing the --without-syno-features option, which makes "btrfs send" compatible with standard Btrfs implementations.

By default, the Synology "btrfs send" command will send a lot of ACLs and maybe other information, a standard btrfs can't deal with.
I've discovered that it's possible to turn this behavior off with
--without-syno-featuresand let it behave like a normalbtrfs send, allowing btrbk to send Snapshots to a non Synology btrfs.Maybe #383 already tried to address this issue, but for me the btrbk run still failed. With this change here, all receive errors are gone.
I've also added an example in the config how to archive all Synology subfolders at once.
