Backblaze automatically backs up all of your data, unless they are explicitly excluded. Your music, photos, files in My Documents, on your Desktop, etc. are all backed up! By default the only files that are excluded are the operating system, applications, and unnecessary files such as your trash, cache folders, and other transient files. Backblaze backs up all individual files, with no size limit.
