Many of us take it for granted that the data we upload, such as the pictures we take today, are stored on a website, or blog articles we write, and will be available online tomorrow. We are increasingly accustomed to relying on Web services, and take this as a matter of course. This assumption is in large part because we assume that these services will still exist tomorrow. These websites are able to visit normal today, but tomorrow may disappear without a trace. In the past few years, we have seen many, many such examples. For example, veteran social networking sites Friendster and GeoCities. The former deleted user data in May this year in order to redesign the website, which closed in 2009.

In other words, nothing is eternal. Our web service hosting data also disappears. When this happens, you need a preventive plan. In the following, we will look at cases where the user data is lost or at what risk of loss, how businesses (and their users) handle the situation, and what steps to take to protect the information.

Eventually shut down the web service

Unfortunately, we've seen many stories about Web services being closed, sold, or missing data.


MySpace was once a popular social network, but was eclipsed by Facebook's rise. MySpace slow death and unsuccessful rebirth, raised some questions about how to deal with existing user data, should find an easy way to export these information.

In 2008, MySpace introduced a feature called "Data Migration Innovation." However, this feature is not for exporting data from MySpace, nor for automatically importing other websites, allowing users to continue using contact information. Even worse, in MySpace's Terms of Service, developers are forbidden to create apps that export user information for use with other services. But that did not stop people from creating tools that tap the MySpace corner, such as Make Data Make Sense's blog exporter.

Google Video

After Google acquired YouTube in 2006, Google Video became redundant. In 2009, Google switched off the upload of new videos to Google Video, but the user's strong protests led Google to eventually shut down all its services, and all videos on Google Video were still archived manually. Users who paid for, downloaded, and owned / rented items they looked for still had access to what they had previously purchased, and those who had a significant amount of on-system fees were able to transfer their costs to Google Checkout (later, Google Announced that they will also provide a credit card refund service.In April 2011, Google announced Google Video content can be retained indefinitely until all the remaining videos are transferred to YouTube). Like other closed Web services, the problem is not just the content above, but also the user's input into the site.


In October 2009, about 800,000 T-Mobile users with Sidekick phones lost all their data due to server failure that stored personal data such as user email, contact information. Initial reports said the data was lost forever, but most of the data was later recovered. This does not mean that T-Mobile and Microsoft, the server responsible for managing Sidekick data, are less affected. Even worse, users can not recover their data in the short term, except for data synchronized with the computer.

Sidekick's data services have been interrupted until May 31, 2011. Microsoft said in a statement that T-Mobile has released an enhanced Web tool at that makes it easy to send their personal data, including contacts, photos, schedules, notes, calendars and browsing Bookmarks, etc. from dangerous services to new devices, computers or designated email accounts. The tragedy above may not happen if they provide such handy tools early in the data outage or as a routine way to allow Sidekick users to store all their data.

Blogging and web hosting services. As blogs and free sites are now a service that is thrown away after use, it is not surprising that these services died in large numbers. GeoCities was once a leader in early Web commercial activity, and the service was shut down in 2009 to convince so many netizens. While Yahoo has largely taken no steps to maintain the site, a large number of third parties are working to save the data on GeoCities. In the meantime, Windows Live Spaces shut down its service in March 2011, though users could choose to migrate their data to WordPress. May 24 this year, Yahoo's MyBlogLog has also been closed. This time provides a tutorial on how to move data out of MyBlogLog.

For users, the issues they face are complex.'s online music service allows users to buy streaming music at a lower price, which was acquired by Apple in December 2009. Users can go to iTunes at, but streaming media music they've purchased before will disappear forever. In other words, there is currently no rule that allows for the purchase of streaming music for legitimate MP3 downloads.

The fate of poses a problem. That is, how many media services offer a "rental" rather than a "buy" model, under what circumstances do users feel they are themselves and to what extent are the users willing to spend money on visits that last only one night s things?

Answers to these questions are no longer a problem as they involve conceptual changes in the characteristics of consumer services and are deeply influenced by the company's reputation. For example, almost no one thinks Amazon will stop serving so buying a Kindle e-book does not have to hesitate to buy streaming music from a young singer.
