    摘要： Preparing source data to be replicated in a continuous data replication environment. Certain systems and methods populate a file name database with entries having a unique file identifier descriptor (FID), short name and a FID of the parent directory of each directory or file on a source storage device. Such information is advantageously gathered during scanning of a live file system without requiring a snapshot of the source storage device. The database can be further used to generate absolute file names associated with data operations to be replayed on a destination storage device. Based on the obtained FIDs, certain embodiments can further combine write operations to be replayed on the destination storage device and/or avoid replicating temporary files to the destination system.

    摘要： Performing data management operations on replicated data in a computer network. Log entries are generated for data management operations of an application executing on a source system. Consistency point entries are used to indicate a time of a known good, or recoverable, state of the application. A destination system is configured to process a copy of the log and consistency point entries to replicate data in a replication volume, the replicated data being a copy of the application data on the source system. When the replicated data represents a known good state of the application, as determined by the consistency point entries, the destination system(s) may perform a storage operation (e.g., snapshot, backup) to copy the replicated data and to logically associate the copied data with a time information (e.g., time stamp) indicative of the source system time when the application was in the known good state.

    摘要： According to certain aspects, a method for performing remote backup operations is provided that includes receiving a first unidirectional connection request from a media agent module to a proxy device within an enterprise network, through a firewall. The method also includes receiving a second unidirectional connection request from a remote device coupled to an untrusted network, such as through a second firewall. Secure connections are established from the media agent module to the proxy and from the remote device to the proxy. Additionally, the method can include routing with the proxy device backup data from the remote computing device to the media agent over the secured connections. The method also may include storing the backup data on a storage device within the enterprise network. In certain embodiments, during establishment of the secure connections, identification of the media agent or the storage device is not exposed to the untrusted network.

    摘要： Systems and methods for providing more efficient handling of I/O requests for clustered file system data subject to data migration or the like. For instance, exemplary systems can more quickly determine if certain files on primary storage represent actual file data or stub data for recalling file data from secondary storage. Certain embodiments utilize a driver cache on each cluster node to maintain a record of recently accessed files that represent regular files (as opposed to stubs). A dual-locking process, using both strict locking and relaxed locking, maintains consistency between driver caches on different nodes and the data of the underlying clustered file system, while providing improved access to the data by the different nodes. Moreover, a signaling process can be used, such as with zero-length files, for alerting drivers on different nodes that data migration is to be performed and/or that the driver caches should be flushed.
