On a unix-ey filesystem with hard links doing
   cp -rl <pictures_filetree> <backup_place>
e.g.
   cp -rl /home/john/pix /home/john/pix.20120531-backup
makes an image of my main image folders in the backup location without 
using (much) extra disk space, since only the directory entries of the 
files are copied, not the files themselves.

It's not bulletproof: since the files are hard-linked any utility that 
changes the contents of the file in one location without breaking the 
link will change it in the other location as well.
