Someday this will happen with Facebook, Vkontakte, Google Drive, Dropbox and any other commercial service. All your files on a cloud hosting will inevitably be lost over time. How this is happening can be seen right now with the example of MySpace, the former Internet giant and the world's largest social network.
About a year ago, users
noticed that links to music files uploaded to MySpace until 2015 stopped working. At first, everyone thought it was some kind of temporary problem.
At first, MySpace representatives promised to sort it out and
said that they were working on the problem. But in the end they were forced to
admit that the data was damaged and lost irrevocably “as a result of server migration”.
Answer to one of the users of the MySpace data privacy law department')
Other users discuss the situation on
this Reddit forum . Apparently, the data is lost until 2015, and this is not only music, but also photos and videos. MySpace did not backup all user data.
Naturally, such problems can occur in every social network. What is the point of storing gigabytes of photos if the user has not logged in to the system for several years (for example, he died). Or why store in “hot storage” on servers with SSD files that have not been accessed for five or more years? At a minimum, they can be written to a tape drive and transferred to a cheap long-term storage. But even in this case, the maintenance of old files costs money. And every year the volume of these files grows, as well as the cost of their maintenance. As soon as the company's business does not allow for ensuring sufficient financial flow to cover these expenses, the files will be destroyed.
In addition, the files on the cloud hosting may disappear right now
as a result of a bug ,
legal arbitrariness of the company , at the
request of the copyright holders or for a million other reasons.
