File Atchitectures: Other possibilites

Amazon S3 Object Versioning

• Ability to store multiple object versions as they are modified
• Helpful to restore a file to a previous version
• Could restore an entire file system to a previous version
• Must use the "RefreshCache" API on the Gateway to be notified of restore

Amazon S3 Object Lock

• Enables to have the file gateway for Write Once Read Many (WORM) data
• If there are file modifications or renames in the file share clients, the file gateway creates a new version of the object without affecting priori version, and the original locked version will remain unchanged 

 

Volume Gateway

• iSCSI protocol
• Need to restore as EBS volume

 

• iSCSI interface
