摘要： One aspect of the present invention includes enabling the efficient transfer of deduplicated data between storage pools in a storage management system without unnecessary reassembly and deduplication of data objects. In one embodiment, the storage management system tracks deduplication information for the data chunks of data objects within an index at the storage management system level, in addition to tracking storage information for each data object within another index at the storage management system level. The data chunk deduplication information is then accessible by any storage pool. Accordingly, transfers of the data objects and data chunks of the data object are easily facilitated, even between non-deduplicating and deduplicating storage pools.

摘要： A source server maintains a replication rule specifying a condition for a replication attribute and a replication action to take if the condition with respect to the replication attribute is satisfied, wherein the replication action indicates to include or exclude the object having an attribute value for the replication attribute that satisfies the condition. For each of the objects, the replication rule is applied by determining an attribute value of the object corresponding to the replication attribute in the replication rule and determining whether the determined attribute value satisfies the condition for the replication attribute defined in the determined replication rule. The replication action on the object in response to determining that the determined attribute value satisfies the condition for the replication attribute.

摘要： Systems and methods for retrieving data from a storage system having a plurality of storage pools are provided. The method comprises processing configurable data retrieval instructions to determine a first storage pool from which target backup data is to be retrieved, in response to a data restore request; and retrieving the target backup data from the first storage pool to satisfy the restore request. The configurable data retrieval instructions are managed by a source external to the storage system with administrative authority to change the configurable data retrieval instructions to optimize data restoration from the storage system.

摘要： The present invention provides for a method, system, and computer program for the application of data deduplication according to a policy-based strategy of tiered data. The method operates by defining a plurality of data storage policies for data in a deduplication system, policies which may be arranged in tiers. Data objects are classified according to a selected data storage policy and are split into data chunks. If the selected data storage policy for the data object does not allow deduplication, the data chunks are stored in a deduplication pool. If the selected data storage policy for the data object allows deduplication, deduplication is performed. The data storage policy may specify a maximum number of references to data chunks, facilitating storage of new copies of the data chunks when the maximum number of references is met.

摘要： Data objects are replicated from a source storage managed by a source server to a target storage managed by a target server. A source list is built of objects at the source server to replicate to the target server. The target server is queried to obtain a target list of objects at the target server. A replication list is built indicating objects on the source list not included on the target list to transfer to the target server. For each object in the replication list, data for the object not already at the target storage is sent to the target server and metadata on the object is sent to the target server to cause the target server to include the metadata in an entry for the object in a target server replication database. An entry for the object is added to a source server replication database.

摘要： 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.
