About managing file and folder backup data

Because drive-based backups capture your entire hard drive, the size of a recovery point is typically much larger than the data that is captured during the file and folder backups. However, file and folder backup data can take up significant disk space if it is not managed. For example, audio files, video files, and photographs are typically large files.

You must decide how many versions of backup files that you want to keep. This decision can depend on how frequently you change the content of your files and how frequently you run the backups.
