This is probabably obvious, but having shot myself in the foot with it in the past, I can't let this go by without pointing it out. If you try this approach, be absolutely sure you use 

tar cf - ./source/directory 

The example here looks like you're using a full, absolute path name starting at root for your source directory. If you write that using a pipe, it goes right back where it started, not to /backup/directory you've just changed into. 

Been there, done it to myself, spent a very long weekend recovering the file system.
