Abstract: Systems and methods for synchronization including the use of a global equivalency identification datum or set of datum. A universally unique identification datum may be associated with each independently created associated data set. In some embodiments, a synchronization server software element may be responsible for maintaining synchronization for a plurality of clients, including software elements or devices. A record believed to be new by the software elements may verify that the record is actually new. In some embodiments, verification of the record's newness involves assuming that the local ID is a global identification datum and comparing that datum to the all the sets of datum that the Sync-Server knows about. The synchronization server software element may use a table to hold information for all of the records known to that element. In some embodiments these records may have been deleted in the past.

Abstract: A method and system is provided for measuring, guaranteeing, and reducing replication data lag time between a primary system and one or more standby systems. Each standby system determines the lag time between the generation of a consistent version of data on the primary system and the time that the consistent version is applied on the standby system. Applications can request and be guaranteed to receive data from a standby system that is identical to the state on the primary system at the time of the query, or lag the primary state only by a maximum tolerable amount. A standby system may also publish a service that guarantees a maximum lag time and withdraw the service offer when the actual lag time exceeds the guaranteed lag time. Implications for implementing synchronous and asynchronous replication as well as performance optimizations are also discussed.

Abstract: Systems and methods for data classification to facilitate and improve data management within an enterprise are described. The disclosed systems and methods evaluate and define data management operations based on data characteristics rather than data location, among other things.

This data structure may be consulted to determine changes in system data rather than scanning the data files themselves.

Abstract: The objects of an archive may be verified with a cryptographic signature stored in the archive. However, when an object is extracted, the authentication involves re-authenticating the entire archive, re-extracting the object, and comparing the extracted object with the current object, which is inefficient or unachievable if the archive is unavailable. Instead, the archive may include a block map signed with the signature and comprising hashcodes for respective blocks of the objects of the archive. When an object is extracted, the signature and block map may also be extracted and stored as objects outside of the archive. The extracted signature and block map may later be verified by authenticating the signature, verifying the block map with the signature, and matching the hashcodes of the block map with those of the blocks of the extracted objects, thus enabling a more efficient and portable verification of extracted object with extracted authentication credentials.

Abstract: Synthetic backups are created without accessing previous backup data or retrieving backup data from a cloud storage service. A backup system provides two or more backup data sets to a cloud spanning storage interface for storage in deduplicated form as label maps and data segments in a cloud storage service. A specification defines portions of two or more previous backup data sets to be copied into the synthetic backup. Labels corresponding with the specified portions of previous backup data sets are identified and added to a new label map to create a deduplicated synthetic backup. The completed label map is transferred to the cloud storage service. To provide access to the synthetic backup, the cloud spanning storage interface reconstructs all or a portion of the synthetic backup from the new label map and the data segments created during deduplication of previous backup data sets.

Abstract: A communication device management program that enables efficient use of memory space in receiving data using remote direct memory access (RDMA) techniques. The receiving node transmits a virtual ID corresponding to a receiving process to a remote sending node. A sending process in the sending node specifies this virtual ID when starting data transmission. If the receiving node has not reserved a memory area corresponding to that virtual ID, the sending node transmits a reservation request to the receiving node, which causes a data receiving memory area to be reserved for use by a communication device in the receiving node. In the sending node, the sending communication device begins sending transmission data in RDMA mode, from a memory area managed by the sending process to the reserved data receiving memory area. The receiving communication device directs incoming transmission data to a memory area managed by the receiving process.

Abstract: One aspect of the present invention includes an optimized simultaneous storage operation for data objects onto a combination of deduplicated and non-deduplicated storage pools. In one embodiment, a data object is provided for storage onto destination storage pools in a storage management system, and placed into a source buffer. The data object is first divided into data chunks if the data object has not previously been chunked within the storage management system. The data object is then simultaneously copied from the source buffer to each destination storage pool (deduplicating and non-deduplicating) with the following operation. If the destination pool utilizes deduplication, then the individual data chunks are only transferred if copies of the individual data chunks do not already exist on the destination storage pool. If the destination pool does not utilize deduplication, then all chunks of the data object are transferred to the destination storage pool.
