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

</div>'tahoe cp -r', but that will unconditionally copy everything. I don't think it<br>
has any advantages for this over 'tahoe backup'.<br></blockquote><div><br></div><div>how does it act if a file already exist on tahoe ?<br><br></div><div>does it upload all files including existing ?<br>or only modified/new files (timestamp) ?<br>

</div>Yes, as far as I know that is a good solution, although I haven't used it myself.<br>
