Abstract: Provided are a computer program product, system, and method for merging multiple point- in-time copies into a merged point-in-time copy. A repository maintains a full copy of the source data and point-in-time copies at point-in-times of the source data. Each of the point- in-time copies have change information indicating changed data in the source data that changed between the point-in-time of the point-in-time copy and a subsequent point-in-time and changed point-in-time data comprising data in the source data as of the point-in-time of the point-in-time copy indicated in the change information as changed. At least two selected of the point-in-time copies in the repository are merged into a merged point-in-time copy by: forming merged change information in the merged point-in-time copy indicating changed data indicated in change information for the selected point-in-time copies; and forming merged changed data in the merged point-in-time copy from the changed data in the selected point-in-time copies.

Abstract: Provided are a computer program product, system, and method for creating a restore copy from a copy of source data in a repository having source data at different point-in-times. All the source data as of an initial point-in-time is copied to a repository. In response to completing point-in-time copies following the initial point-in-time, change information is transmitted to the repository indicating changed data in the source data that changed between the point-in-time of the point-in-time copy and a subsequent point-in-time. For each point-in-time copy, copying changed source data comprising source data indicated in the change information for the point-in-time copy as changed to the repository. A restore request is received to restore the source data as of a restore point-in-time. The source data in the repository as of the restore point-in-time is copied from the repository to a restore copy.

Abstract: Computer implemented methods for concurrent processing of operations on a tree-based data structure include: receiving input at a storage system managing a storage device in which the tree-based data structure is stored, the input identifying a set of heterogeneous operations to be applied to the tree-based data structure; determining one or more nodes of the tree-based data structure to which one or more of the set of heterogeneous operations are to be applied; and performing one or more of the set of heterogeneous operations concurrently and in bulk. Systems and methods for accomplishing the same are also disclosed.

Abstract: A computer program product, system, and method for creating a restore copy (124) from a copy of source data (104) in a repository (110) having source data (104) at different point-in- times. All the source data (104) as of an initial point-in-time is copied to a repository (110). In response to completing point-in-time copies following the initial point-in-time, change information is transmitted to the repository (110) indicating changed data (120) in the source data (104) that changed between the point-in-time of the point-in-time copy and a subsequent point-in-time. For each point-in-time copy, copying changed source data comprising source data (104) indicated in the change information for the point-in-time copy as changed to the repository (110). A restore request is received to restore the source data (104) as of a restore point-in-time. The source data (104) in the repository (110) as of the restore point-in-time is copied from the repository (110) to a restore copy (124).
