On last Sunday, evening some of the Gmail users,noticed that their inboxes empty and many users gmail account was also not available during that period. Google has blamed a bug for this problem that deleted an estimated 40,000 Gmail accounts. The Google named this bug as “Snafu”, which affected around 0.02% of the total 170 million Gmail  users.

But, recently Google said that the emails were never lost and that things should be back to normal for everyone soon. Ben Treynor, Google’s site reliability czar said in the firms official blog that”I know what some of you are thinking: how could this happen if we have multiple copies of your data, in multiple data centres”.Snafu Bug Is Responsible for Gmail Mail Deletion

“Well, in some rare instances software bugs can affect several copies of the data. That’s what happened here,” he added

He said that Google backs up data on an offline tap, which is protected by software bugs. So restoring data from them takes longer than usual, as it takes time to transfer data from one data centre to another.

Now, Google is using older version of its storage software which is more reliable against  bug.
