yeah hardware issues happen, it's unfortunate but it happens on a very regular basis. backups are important

On one hand, I agree with you. On the other hand, you say this is a hardware issue but do you know for a fact that is what happened? Migration sounds to me like you migrate data from one state to the other state, then delete the old state. To me, it would be logical that before you delete the old state, you verify whether the migration was successful.

  providers like this dont migrate data for no reason. there was probably a bad drive in the array or something, or some other known defect, so they are opting to migrate off the host before things get worse

The idea behind cloud services is that you pay someone to manage that.

  Yup it's ironic however how in the end you have to manage that stuff yourself anyway.

    It depends how the vendor presents and handles it. I'm not aware how RS promises look. However, for example, the hetzner cloud has an explicit choice between triple-redundant ceph-based storage for VMs, or hypervisor local SSD storage. That's good and explicit. I can make an informed choice about speed or durability.

      > triple-redundant ceph-based storage Just to point out, that's still not a backup system. That's only one software bug (in your systems or theirs) away from having no working current data set. ;)

        Yes, I did not mean to imply it is a backup. You still need backups. However, that redundant storage takes care of .. well redundancy, if you need it. Storage with zero redundancy on the drive or the service level (think of ES) is stressful to say the least.

  I think the idea is that these simple storage volumes are much lower-level than that. If you backed them up automatically it'd be hard to provide the performance that people are using them to get. You build durable storage on top of simple storage volumes.

  Especially Rackspace -- isn't their price tag because its all managed hosting?
