Unfortunately, sometimes symlinks themselves contain information in their target, thus you cannot simple use "follow symlinks" in your backups.Well, no: you really have to back up the symlinks *as symlinks*, and similarly for all other non-regular filetypes (or the first time you hit a non-connected FIFO, or /dev/zero, you'll never come back).
Every halfway-competent backup program does this, even `cp -a'.
