(Note that in English we'd normally write 1 TB or Tbyte for this. "Octet" is also a
rarely-used synonym for "byte" in English, but it is not used for the abbreviations.)

That is ticket <https://tahoe-lafs.org/trac/tahoe-lafs/ticket/1433>.

Note that those files actually have been uploaded, so if you repeat the backup,
it will complete sooner and using less total bandwidth than it otherwise would
have, because it is using the already-uploaded files. However no files will be
accessible until a backup has completed.

'tahoe cp -r', but that will unconditionally copy everything. I don't think it
has any advantages for this over 'tahoe backup'.

Yes, as far as I know that is a good solution, although I haven't used it myself.
