This is what I ended up using. I did

dir=$(dirname $file)
filename=$(basename $file)
rsync -a --backup --backup-dir=$dir/Versions --suffix=.$(date +%Y%m%d)
 --include=$filename --exclude=* $dir/ remote:$dir/

Since I am putting the backups in the same dir as the file being 
synced, I dont risk any collisions.

Works like a charm.

Thanks everyone.
