Microsoft announced early this morning that it has managed to recover “most, if not all” of the data stored by T-Mobile Sidekick users on its servers. Previously, this data had been thought lost.
Nearly two weeks ago, the servers for the Sidekick service ran into a problem — a problem serious enough that synchronization with handsets stopped, and T-Mobile warned users that the online copy of their data was probably irretrievable. This meant the data stored on their phones was the only copy remaining.
Today, the news is much rosier. Engineers for Microsoft — whose Danger, Inc. subsidiary is responsible for the Sidekick software and service — were able to fix the problem.
According to a statement from Microsoft’s Roz Ho:
We have determined that the outage was caused by a system failure that created data loss in the core database and the back-up. We rebuilt the system component by component, recovering data along the way. This careful process has taken a significant amount of time, but was necessary to preserve the integrity of the data.
Ho goes on say that a “minority” of users may have nevertheless lost their data. Those who have are urged to visit the official T-Mobile Sidekick forums.
Microsoft also promises it has “made changes to improve the overall stability of the Sidekick Service and initiated a more resilient backup process to ensure that the integrity of our database backups is maintained.”
