What is the name of the program that distributes copies of folders on different disks under Windows instead of RAID?

Question

Windows

In one of the articles on Habré, it was mentioned that raid for a home server is an expensive and redundant thing for storing movies and TV shows, and a program was offered that sets up copying folders to different drives. For example, movies are only on one disk, but a folder of photos is in three copies on different disks.
The author wrote that this particular program is available only under Windows. The site was in English. I can't remember the name and I can't find the article in my bookmarks.
What is the name of this program?
