It is impossible to use any rsync, rdiff, or rdiff-backup commands against a
remote server without the corresponding daemon running on that server, as the
commands omit sending as many data blocks as possible by sending block
signatures instead, then on signature mismatch sending the data black and
storing it in the new file copy, an incremental diff, and/or a date-time stamped
backup.

I would expect it to support specs in the form of rsync URIs, not general URI
schemes as supported by curl or duplicity e.g.
rsync(1):
" Access via rsync daemon:
Pull: rsync [OPTION...] [USER@]HOST::SRC... [DEST]
rsync [OPTION...] rsync://[USER@]HOST[:PORT]/SRC... [DEST]
Push: rsync [OPTION...] SRC... [USER@]HOST::DEST
rsync [OPTION...] SRC... rsync://[USER@]HOST[:PORT]/DEST
Usages with just one SRC arg and no DEST arg will list the source files
instead of copying."
similar to ssh(1):
"or a URI of the form ssh://[user@]hostname[:port]"
