help! How to backup /sdcard/ (internal sd card) to directories?

I’d like to have a regular recurring backup (like nightly or daily) of /sdcard/Kindle and /sdcard/Nook

e-books (and housekeeping files) to my cloud storage. It looks like this app is designed

to do what I’m looking for.

I have directories setup to receive the data. I’ve manually uploaded the files,

but the process is slow and I want to automate it as much as possible,

Due to changes in Android’s design, /sdcard is no longer the external sdcard.

When /sdcard was really the sd card I could take the card out of the phone

put it in my laptop and sync the data to my desktop Smiley Sad.
