I'd suggest taking this into consideration as a backup strategy. The idea that there must be enough free space to include old AND new files doesn't seem to be useful.
I'm having the same problem on a drive that has temporary video files. The disk was nearly full. I deleted 69 GB of video, and added 32 GB of new video --- note that was 69GB in a single file, and 32GB in a single file.
"No space left on device."
If nothing else, perhaps you could create a queue of failed files and make a second pass, when space has been freed.
@Twitch: You could also look at using rsync from the command line. Be sure to include the -E switch to enable Apple extended attributes. Be darned careful with whether the directories have a trailing / or not; you could end up deleting lots of stuff you didn't intend.
Code:
rsync -EaSv --progress --delete /Volumes/Source/ /Volumes/Destination/
