Abstract
In one embodiment, an apparatus includes a processor and logic integrated with and/or executable by the processor configured to cause the processor to receive data to store to a first cluster, store one or more copies of the data to the first cluster, and set a time-delayed copy consistency point time-delayed cops consistency point indicating an amount of time in which data stored to the first cluster is aged prior to being copied from the first cluster to a second cluster. In another embodiment, a method for time-delayed replication includes receiving data to store to a first cluster, storing one or more copies of the data to the first cluster, and setting a time-delayed copy consistency point, the time-delayed copy consistency point indicating an amount of time in which data stored to the first cluster is aged prior to being copied from the first cluster to a second cluster.
