In 2019, the social networking site MySpace announced that they lost almost all music, image and video data uploaded between 2003 and 2015 when migrating the data to a new server. According to MySpace, there is no back-up for the lost data. At the outset, the online platform was primarily intended for musicians to present their works and was comprised of more than 50 million pieces of music. This includes early works by artists who started their careers on MySpace. Especially for older posts, there are often no local copies of users because they relied on storage in the cloud. Thus, the works may be lost forever.
The example shows very well that it always makes sense to store files in more than one place. A good basis for securely storing data is provided by the 3-2-1 rule. It stipulates, that data should be backed up to at least 2 different storage media in three different locations one of which should be off-site.
