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： A system and method for relating files in a distributed data storage environment allows for positive identification of membership of a file within a group, even in a loosely coupled environment where files are not available for comparison in real time. In disclosed embodiments, base files of a client are stored on a server and are accompanied by tokens uniquely identifying the base files. The tokens are generated on the client and may be derived from the contents of the base file using a digital signature. Each file transmitted to the server is accompanied with a token. Incremental backups may be used, and may employ file differencing. Accordingly, sub-files related to the base files may be transmitted to the server for backup. The sub-files are related to their respective base files using the tokens and are cross-linked to the base files so that any sub-files can be retrieved together with the base file from which the sub-file was derived.

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： A system and method for transferring related data objects in a distributed data storage environment allows for data objects belonging to a common group to be transferred while preserving the grouping of the data objects. The data objects can be transferred in an order in which the data objects are stored, rather than in an order of grouping. The data objects are accompanied with attribute information including a unique group identifier when transferred from a source site to a target site. At the target site, the attribute information for each data object is received and analyzed. An import groups table listing the groups of data objects is used to associate each data object with its group as it is received. Data objects of groups for which any members have not been received are also listed in an unresolved objects table. When a group is complete, all data objects of the group are removed from the unresolved objects table. At the end of a data transfer session, all data objects still listed in the unresolved objects table are deleted.

摘要： A process is disclosed by which data is securely deleted in a transactionally consistent manner. This may be accomplished by committing a preparation transaction for a data object within a system managing the data object in order to return the system to an initial condition if necessary, attempting to commit an execution transaction with the data object only after committing the preparation transaction, and securely deleting any portion of the data object necessary to return the system to the initial condition if committing the execution transaction fails and to change the system to a completed condition only if committing the execution transaction succeeds. In a delete or move transaction an existing backup object may be assigned a new logically deleted state such that if the delete or move transaction fails, the data will be made accessible again.
