Zusammenfassung:A computer-implemented method, according to one embodiment, includes: monitoring data requests that are performed on a logical volume in memory at a source location, and tracking changes that are made to data in the logical volume as a result of performing the data requests. A determination is made as to whether a preestablished amount of the data in the logical volume has been changed as a result of performing the data requests since a previous snapshot of the logical volume was captured. Moreover, in response to determining that a preestablished amount of the data in the logical volume has been changed as a result of performing the data requests since a previous snapshot of the logical volume was captured, a new snapshot of the logical volume is captured.
