Abstract: Techniques for integrating backup applications and/or modules with virtualized storage are disclosed. In one particular exemplary embodiment, the techniques may be realized as a computer implemented method for integrating a backup module with a storage appliance comprising sending a storage device command to a source storage appliance from a source backup module, executing at the source storage appliance the storage device command, and updating one or more source storage indicators associated with the source storage appliance, wherein the one or more source storage indicators include replication status information for one or more portions of electronic storage associated with the source storage appliance.

Abstract: Techniques for providing multiple levels of security for backups are disclosed. In one particular exemplary embodiment, the techniques may be realized as a method for providing multiple levels of security for a backup medium comprising protecting a data portion of the backup medium with a first security mechanism, and protecting a metadata portion of the backup medium with a second security mechanism.

Abstract: A system includes shared Small Computer System Interface (SCSI) storage devices for processing clients coupled by a fiber channel interface. The storage devices include storage blocks, and locks controlling their use by clients. Clients issue actions to the storage devices for performing operations on the locks. A client may exclude other clients from using storage blocks using a state element to acquire the lock for shared or exclusive use. If the client modified the data, a version counter in the lock is updated when the lock is released. If an activity bit is set, the version counter is updated upon both reading and writing. Other clients can forcibly release a lock owned by a failed client by monitoring its version counter. Expiration timers associated with the locks allow acquired locks to be released by timing out. A serverless global file system (GFS) manages use of the shared storage resources, and allows remapping of the locks to the storage blocks, for example, based on activity of the locks.
