rsync can resume partial transfers but does so by copying the upload "so
far" rather than just appending to it (though there are good reasons for
this), so to upload a 70GB file with the option of resuming you would
need up to 140GB of available space...

The use of split(1) is a good suggestion, though I do recommend
verifying the integrity of the files before & after with md5sum/sha1sum
or using the -c (md4 checksum) flag on rsync for the final pass.
