If you care about your data, you back it up. Period, end of discussion.
And, by the way, Amazon has irretrievably lost customer data before.
A few days ago we sent you an email letting you know that we were working on recovering an inconsistent data snapshot of one or more of your Amazon EBS volumes. We are very sorry, but ultimately our efforts to manually recover your volume were unsuccessful. The hardware failed in such a way that we could not forensically restore the data.
What we were able to recover has been made available via a snapshot, although the data is in such a state that it may have little to no utility...
If you have no need for this snapshot, please delete it to avoid incurring storage charges.
We apologize for this volume loss and any impact to your business.
Amazon Web Services, EBS Support
