Abstract
Exemplary storage network architectures, data architectures, and methods for data restore operation are disclosed. In one embodiment, a storage device comprises a processor, a memory module communicatively connected to the processor, and logic instructions in the memory module which, when executed by the processor, configure the processor to receive a signal that identifies a source volume and a first target snapshot that represents a point in time copy of the source volume, update metadata to define an restore relationship between the first target snapshot and the source volume, execute a background copy process between the first target snapshot and the source volume, and manage input/output operations during the background copy process to permit input/output operations to the source volume during the background copy process.
