re redundancy i assume this is correct. A disk failure should be transparent. However this can easily be accomplished with raid, which may double the disk cost

re redundancy i assume this is correct. A disk failure should be transparent. However this can easily be accomplished with raid, which may double the disk cost but not much more. As for backups, this price does not include backing up.
- rbanffy 16y agoEven if they don't give you the backups, the array should be backed up. They couldn't afford to lose your data. And redundancy does not only increase the cost of the physical, it also increases maintenance, since the devices fail and have to be replaced. Also, we are not talking hard disks here. If a server, memory, processor or anything else fails, it will be replaced and your virtual machine (and all others that happen to run on the failed hardware) will be migrated to another chassis so it can continue running. If they have supernaturally high availability, it could even be running in sync on two different boxes with smooth handover in case one fails and you won't even notice there was a glitch. But I guess that's too much to ask yet. I am not aware this kind of technology has been developed.
