摘要： The invention provides systems and methods for continuous back up of data stored on a computer network. To this end the systems of the invention include a synchronization process that replicates selected source data files data stored on the network and to create a corresponding set of replicated data files, called the target data files, that are stored on a back up server. This synchronization process builds a baseline data structure of target data files. In parallel to this synchronization process, the system includes a dynamic replication process that includes a plurality of agents, each of which monitors a portion of the source data files to detect and capture, at the byte-level, changes to the source data files. Each agent may record the changes to a respective journal file, and as the dynamic replication process detects that the journal files contain data, the journal files are transferred or copied to the back up server so that the captured changes can be written to the appropriate ones of the target data files.

摘要： In a storage system having a source storage system and target storage system, systems and methods maintain information from which a set of source data files stored on a storage system can be retrieved. In one embodiment, baseline images of one or more source data files are stored in target files of the target storage system. For a selected target storage time, locations in the source storage system where changes have been made since a previous target storage time are dynamically identified. Contents that occupy the locations are read and sent to the target storage system. The contents are stored in the target storage system together with associations of the contents with the locations.

摘要： A system for backing up data files generates information from which those files can be recovered, and it sends that information to a back-up location. To determine what information to send, it generates summaries of those files from time to time and identifies changed locations by comparing the summaries with one another. As a consequence, the information it sends the back-up location can be limited to the identities and new contents of the locations thereby identified.

摘要： Disclosed are systems and methods for backing up data files. In one embodiment, a method of backing up data files can include detecting changed locations in one or more data files, storing the contents of the changed locations at a storage time, and associating the stored contents with: the storage time, the changed locations, and one or more file identifiers identifying the one or more data files.
