backup to two different disks

Looking for software or a way to...
I save a file to a folder, this folder is copied to a local disk and a disk that is my basement.
This disk could be a PC or a network drive

Example, Google Drive, Dropbox...when I save to these folders the file is auto copied to the web...the file is in two different places.

My files are 1MB - 1GB ...so I rather copy the local.

Ideas...Thanks

Maybe VB Script could be the solution
Check file in folder
Compare to Disk-Folder 1 and Disk-Folder 2
If different ..Copy file to 1 and 2

Any ideas?

This is really inexpensive - I use it...
