Abstract: A computer-implemented method according to one aspect includes monitoring a current usage of a backup storage space for a storage volume; comparing the current usage to a capacity threshold; and conditionally increasing a size of the backup storage space, based on the comparing and a predetermined size limitation.

Abstract: Ensuring that enterprise data that has potentially become corrupted is recoverable and usable by creating safeguarded copy volumes of the enterprise data. One important aspect of any corruption detection scheme is to determine when the data has become corrupted and locate the last known uncorrupted copy of the data as quickly as possible. Once this set of data is identified, the restoration process can begin with that data, and subsequent logged transactions can be reapplied if possible, which brings the data to the most recent and uncorrupted version.

Abstract: Providing fine granularity read access to generational copies of safeguarded copy data. In some instances, a fine granularity read access to generational copies of safeguarded copy data includes the ability to use a generation ID to determine the exact generation copy that contains relevant enterprise related data that must be recovered and/or utilized. Additionally, the fine granularity read access is done in a manner that does not require a restore of the relevant enterprise related data to a recovery volume and that does not compromise other generation copies.

Abstract: A computer-implemented method according to one embodiment includes receiving a request to withdraw a point-in-time snapshot copy operation being implemented by a data consistency application; in response to determining that the data consistency application is creating a current consistency group, maintaining the withdrawal request while allowing the creation of the current consistency group by the data consistency application; and in response to determining that the data consistency application is idle, preventing a formation of a new consistency group by the data consistency application during the withdrawal of the point-in-time snapshot copy operation.

Abstract: Aspects of the invention include a continuous availability for workload and site switches with no data loss at unlimited distances in an active-active sites configuration. A non-limiting example computer-implemented method includes synchronously replicating commit records of changed workload data, by a processor, from an active site to a bunker site upon a workload data commit. The method asynchronously replicates committed transactions on changed workload data, by the processor, from the bunker site to a recovery site.

Abstract: A method for performing a write to a volume x in a cascaded architecture is described. In one embodiment, such a method includes determining whether the volume x has a child volume, wherein each of the volume x and the child volume have a target bit map (TBM) associated therewith. The method then determines whether the TBMs of both the volume x and the child volume are set. If the TBMs are set, the method finds a higher source (HS) volume from which to copy the desired data to the child volume. Finding the HS volume includes travelling up the cascaded architecture until the source of the data is found. Once the HS volume is found, the method copies the data from the HS volume to the child volume and performs the write to the volume x. A method for performing a read is also disclosed herein.

Abstract: A method for performing a write to a volume x in a cyclic point-in-time-copy architecture is described. In one embodiment, such a method includes determining whether the volume x has a child volume. The method then determines whether the target bit maps (TBMs) of both the volume x and the child volume are set. If the TBMs are set, the method finds a higher source (HS) volume from which to copy the desired data to the child volume. Once the HS volume is found, the method determines whether the HS volume and the child volume are the same volume. If the HS volume and the child volume are not the same volume, the method copies the data from the HS volume to the child volume. The method then performs the write to the volume x.

Abstract: A method for deleting a relation between a source and a target in a multi-target architecture is described. The multi-target architecture includes a source and multiple targets mapped thereto. In one embodiment, such a method includes initially identifying a relation for deletion from the multi-target architecture. A target associated with the relation is then identified. The method then identifies a sibling target that inherits data from the target. Once the target and the sibling target are identified, the method copies the data from the target to the sibling target. The relation between the source and the target is then deleted. A corresponding computer program product is also disclosed and claimed herein.
