Automatic Raw Backup to Network Share

How can I go about setting up Acronis to monitor X files (total of 4 as of now, about 10-30MB ea) to automatically copy to a network destination whenever the file has changed? In "Other backups > File backup" it only let's me save as .tib, .zip, and .vhd. I need it just to copy the files. Specifically, they're excel files and when I modify and save them, they need to automatically copy to the server so they can be accessed via SSH by novice users who can then open them up directly in excel, and me working directly on the server is not an ideal solution.
