| Except to get the same redundancy as this AWS product you would need a replica of this storage device in at least 2 other datacentres, you would have to ensure you have enough spare capacity lying around for any snapshots you take and have to buy or build software that manages this 3-way data synchronisation between sites. Also, you seem to be forgetting that you still need local storage for your images anyway. This is a hands-off backup and disaster recovery product. For full disclosure, the Storage Gateway's pricing isn't the same as S3's at the moment. They only have one storage tier and it is $0.14 per GB, no discounts. Therefore, 50TB of storage over 5 years is $420k. Having said that, what would it cost to: * Not only have your primary but 2 x secondary PS61000E's. * 2 extra datacentres with connectivity to themselvse and your primary site. * Software to manage asynchronous streaming of data from your primary to 2 x secondaries. * Software to take consistent backups of these images and store in at all three locations. * Software to ensure that your secondary sites contain only encrypted data. * Cold-spare hardware at a secondary site capable of running all your images. |
