摘要： Data storage services are provided for clients for backup of data objects from the clients. A data object is sent to a first location in a first storage device. A determination is made if the data object was successfully stored at the first location, and if so, meta data corresponding with the data object is stored, wherein the meta data includes first path information on a first data path of the data object to the first location. The data object is migrated from the first location to a second location in a second storage device. A determination is made if the data object was successfully stored at the second location, and if so, second path information on a second data path of the data object is added to the second location to the meta data corresponding with the data object, to update the meta data.

摘要： An example of a method for error tracking includes sending a data object to a first location. This example also includes determining if the data object was successfully stored at the first location, and if so, storing meta data corresponding with the data object, wherein the meta data includes first path information. This example of the method also includes sending the data object to a second location. This example further includes determining if the data object was successfully stored at the second location, and if so, adding second path information to the meta data corresponding with the data object, to update the meta data. Some examples of the invention may be called a data centric error tracking and problem analysis method (and system), because the error tracking is generally based on the path traveled by the data.

摘要： Methods, computer systems, and computer program products for replicating data are provided. Meta-data and data associated with the meta-data are received at a first data server. A new portion of the data that is not already stored on the first data server is identified. The new portion of the data is stored on a second data server before the meta-data is stored on the second data server.

摘要： In each of a number of passes to deduplicate a data object, a transaction is started. Where an offset into the object has previously been set, the offset is retrieved; otherwise, the offset is set to reference a beginning of the object. A portion of the object beginning at the offset is deduplicated until an end-of-transaction criterion has been satisfied. The transaction is ended to commit deduplication; where the object has not yet been completely deduplicated, the offset is moved just past where deduplication has already occurred. The object is locked during each pass; other processes cannot access the object during each pass, but can access the object between passes. Each pass is relatively short, so the length of time in which the object is inaccessible is relatively short. By comparison, deduplicating an object within a single pass prevents other processes from accessing the object for a longer time.

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.

An entry for the object is added to a source server replication database.
