No you don't. While agree everyone should have their own backups, you should expect your hosting company to properly replicate and backup their datacenters.
Pretending that the cloud is permanent in infallible is extremely dangerous. I would seriously question the competence of any sysadmin relying on this as a base principle.
Sure, they screwed up, but this stuff happens. We should actually be happy it happens "only" on a "small-ish" provider like Gandi and not an entire AZ at Amazon.
Can't wait for that shoe to drop, I'll bring the popcorn, if there's anything left of civilization then...
As far as I understand correctly they only made snapshots on the same machine, which is why there's trouble to begin with.
Considering they're currently "reminding" customers that backups are an industry standard right after losing data due to missing backups I wouldn't just shrug it off.
The fun, of course, starts that one time when it does not work and you realize that no one looked at the corner case that bit you.
Backups aren't free. Replication isn't free. DR isn't free. If a customer isn't paying a premium for them, they aren't getting them. Read the terms of service.
See full thread. Snapshots are marketed as backups.
Intelligent people can argue all day about whether a snapshot should be considered a backup or not, but it won't change the fact that a snapshot doesn't provide any protection from a failure in the underlying storage and it's ridiculously foolish for the owner of data to solely rely on snapshots as their backup strategy.
That depends on how snapshot storage is implemented by the hosting provider. They can use different storage for it, or tapes or whatever. On AWS I can easily have my snapshots on Glacier or copy them to a different data center.
Having cloud provider X say they moved the bits from one place to another should not be considered a backup by anyone, regardless of what they advertise.
- Was this mostly a power loss or a data loss?
- If data loss, did this affect EBS (which has had a claimed annual failure rate of 0.2% - 0.5% or so if I remember) or S3 (much lower failure rate). Remember, EBS WILL have volumes go bad - that's in the docs, they recommend snapshots, aws backup manager etc if you need higher durability.
