Gmail: Google Uses Tape Drives For Backups

gmail logoGmail screwed up yesterday due to a bug from a software update:

Imagine the sinking feeling of logging in to your Gmail account and finding it empty. That’s what happened to 0.02% of Gmail users yesterday, and we’re very sorry.

There are about 170 million Gmail users. 0.02% of 170 million is 34,000.

They’re in the process of restoring all lost email, but what surprised me is they use tape backups.

Tape backup technology has been around since the 1950s. It’s used by every major corporation – it’s the final backup solution – backups of backups resort to tapes in the end, despite their failure rate.

I use an external hard-drive, but tape drives are cheaper (in the long run).
