CSGs are used to transfer data, including backup images, to a storage-as-a-service provider. CSGs can run on physical or virtual machines and hold data on the LAN until it is time to transfer to the cloud. Users access data through the LAN connection, instead of the slower WAN.
Speed is one of the big benefits to using a CSG together with an image-based backup solution. There are cost and convenience benefits as well – provided the backup solution has the features and functionality needed to optimize CSG use.
So, what are the benefits of using a cloud storage gateway with image-level backups? I see four major ones:
When I talk about the benefits of using the two technologies together I'm assuming that the VM backup software has the following capabilities that support efficient operations:
Like much about the cloud, CSGs are relatively new and subject to change. These are my initial observations and lessons learned about using image-based backup with cloud storage gateways; please share yours.
