    摘要： Provided are a method, system and program for maintaining and using information on updates to a data group after a logical copy is made of the data group. A first logical copy of a data group in a storage at a first point-in-time is established. The first logical copy maintains data to reconstruct the data group as of the first point-in time after the data group has been updated following the first-point-in time. Indication is made of regions of the data group updated at the storage after establishing the first logical copy. A second logical copy of the data group in the storage at a second point-in-time is established. The second logical copy maintains data to reconstruct the data group as of the second point-in time after the data group has been updated following the second point-in time. The indicated regions of the data group updated between the first and second points-in-time are saved in a change list.

    摘要： Provided are a method, system, and program that processes a file request to operate on a target file that is directed to a file system. A determination is made as to whether a rule specifies a file attribute satisfied by the target file. In response to determining that the target file satisfies the file attribute of the determined rule, a determination is made as to whether a condition specified by the determined rule is satisfied. In response to determining that the condition is satisfied, an action specified by the determined rule is performed. The file request is forwarded to the file system to execute if the rule does not inhibit the file request.

    摘要： Provided are a method, system, and program for processing a request to update a file in a file system with update data. The update request to a target file that is directed to the file system is processed, wherein the target file is in a mirror copy relationship with a mirror file. A determination is made as to whether a copy operation from the target file to the mirror file is in progress and whether bytes to update in the target file have been copied to the mirror file in response to determining that the copy operation is in progress. The update data is copied to the bytes to update in the target file in response to determining that the bytes to update have not been copied to the mirror file, wherein the update data is subsequently copied to the mirror file during subsequent progress of the copy operation.

    摘要： Provided are a method, system, and program for migrating source data to target data. A write request is received to write application data to source data not yet migrated to the target data. Information is generated for the write request indicating the source data to which the application data is written. The application data is written to the source data. A request is received to migrate source data to target data and indication is returned to retry the request to migrate in response to determining that the requested source data to migrate overlaps source data indicated in the generated information for one write request.

    摘要： Described are embodiments of an invention for prioritizing data items for backup in a computing environment. The computing environment includes a plurality of clients coupled through a network to a backup system for backing up items stored locally on the client. Each client includes a continuous data protection (CDP) module that prioritizes the order of files transmitted to the backup system for storage on one or more storage devices based on policy. The CDP module builds an initial backup list and a CDP backup list. The initial backup list includes any item that meets the criteria of the initial backup profile. The CDP backup list includes items that have been modified since the initial backup process began. The data that is the most critical to a user is often the most recently modified data. Thus, the CDP module preferentially performs a backup of items on the CDP backup list.
