Is it possible to automatically sync or schedule backup from windows desktop to Amazon cloud drive?

odrive supports syncing to/from various cloud storage services, including Amazon Cloud Drive. I've found it to be a decent piece of software, though the CPU usage is a bit high at times on my Windows 8 machine. Good functionality, though. Access to multiple cloud storage solutions in a Dropbox-like way with a single client program.

EDIT: I've found a solution to the high CPU usage on Windows; if I disable "expand to current location" by right-clicking in the folder pane of File Explorer, then it no longer noticeably bogs the CPU down.

In addition to the Windows (7+) and Mac GUI versions, they also now have a "headless" version which runs on Linux, Windows, or Mac (using Python, so perhaps anywhere Python will run as well?)

So, now I can more wholeheartedly endorse it as something that can provide a Dropbox-like file syncing experience with Amazon Cloud drive.

I also found Cloudberry's offerings to be useful for manually copying back and forth from my older Win XP machine, which odrive will not support.

Saw Heavyd's comment, don't know how supporting Amazon Cloud Drive was in 2014 when you posted, but I checked it and CloudBerry for sure do now. To be exact, here's a direct link to CloudBerry for Amazon Cloud Drive.
Never used it yet, but was pleased to see the price. I bet it will help you to automate the backup.

And Yuriy Galanter your second link is broken unfortunately, I was curious to see some 'magic'.
