Backup solution where you can restore an individual file?

I'm currently using an incremental backup system for my business that copies files over at different intervals. The backups are daily, weekly, even month, odd month, etc, in different folders. It's using Goodsync, which is actually a file sync software, but it allows scheduled syncs. It doesn't create a disk image or something. The advantage is that I have access to old files without restoring a gigantic image. The clear disadvantage is that it takes a booty-ton of space because each backup interval duplicates the files.

Is there an easy-to-use backup solution that does incremental backups but I can comb through the directories and restore an individual file? It has to be easy to use (i.e. Windows with a GUI) because employees have to be able to use it, and they don't know jack about Linux.

I'm not planning on hiring an IT person to sort this out. For better or worse, I do all the IT stuff for my small business. Gives me full control and knowledge about how things work. I Docker-ified a lot of stuff, which helps tremendously, but I don't think backups is something that should be done in Linux or Docker for my particular needs. Should be easy-peasy Windows.
