Online Backup and Storage FAQ

How Much Storage Do I Need?

The amount of storage you need will depend on the types of files you want to store. Generally, every digital music file (mp3) is between 3 and 4 MBs. High resolution digital photos and video files can range from 5 MB to hundreds of MB. Finally, full-length digital movies usually range from 700 MB to 3 GB depending on the length and quality of the movie. However, many online storage services offer an unlimited amount of file storage so you can store as many files as you want.

These files are also physically stored (usually at a secure server farm) but for you it is like your files simply exist between all of the devices you use to access them.
