Abstract:
1. A method for implementing a data protection policy in a logical namespace of a storage system environment comprising: monitoring failures of a primary data object in the logical namespace at a managed data object level utilizing a data protection policy wherein the data protection policy is applied to one or more data protected link points to specify the failover action to be taken on each link point; in response to a failure to the primary data object, communicating with a remote agent to create a secondary data object on a destination mirror by utilizing data previously mirrored from the failed data object, wherein creating the secondary data object enables failover for a data protected link point to the primary data object via the data protection policy; in response to creating the secondary data object on the destination mirror, inserting the secondary data object into the logical namespace by issuing a system call to the remote agent to create a new entry in the logical namespace; and linking the secondary data object to the data protected link point in the logical namespace to specify the failover action to be taken on the data protected link point.
