Using Syncback for scheduled backups because...well, just because. I've used it so long I never needed anything else for timed backups even though I'm sure there is much better.

But the one I use the most is Microsofts SynchToy. Small, simple and you can set it up to just synch what you want it to. Price is not TO outrageous. Umm, free, actually. They do have a ver2 but the 1.4 seems to be better. This is an on demand sync program instead of scheduled but then that would probably be best for matching up with a reader.
