Comment 21 for bug 257211

rsync 3 gracefully degrades and properly supports older rsync (as both a client and server).

I know because we have a mix of rsync server in production, at my work, transferring ~10Gb between sites.

As the machines are re-installed with Hardy, we are also installing our own backport; it would be advantageous for the Ubuntu community to have all the features that rsync offers (identified earlier) easily available to them.
