A quick tutorial why you should use Total Commander for Windows and why is it awesome for backups. It is really easy to use and reliable way to back up stuff.
One more thing I forgot to mention in this video: if the blue arrow to the left is not enabled, Total Commander won't delete files at the Right side, that are absent on the left side. So folder at the right is merged, not replaced.
If asymmetric option is enabled and "blue arrow left" is enabled, TC will mark files that are going to be deleted on the right side.
If asymmetric option is disabled, blue arrow left will mark the files that are going be copied left. So folders on both sides will get merged and share each other's content.
