Is there any reason the rsync option --partial couldn't be implemented
in perl-File-RsyncP (if not already there)? This would presumably
allow partial backups of single files to be resumed. Not sure how hard
it would be but intuitively, I wouldn't think it would be too hard.

This could be important when backing up large files (e.g., video,
databases, isos) and in particular over a slow link.
