Yes, most of them are similar in overall cocept. I use a different one, Aomei ( very good free standard version available).
Image partitions/drives/system and file backup. Manual/scheduled. Clone partition/drive. Full/incremental/differential. Restore partition/drive/system/files from image. Resize partitions during restore.
Overall it offers more than any other free version. It is also small, fast, unintrusive and makes pe recovery media without needing a large download.
You might want to look at a couple and see what you like. E.G. Paragon free doesn't have as many features as Aomei, and it is a lot bigger, but it does have a couple of different features. It can exclude files/folders from images, which might be useful to you, or not.
Depends what you want.
