A system can include a memory device and a processing device operatively coupled with the memory device, to perform operations of maintaining a set of data items reflective of a state of a host application and receiving a first request to make a checkpoint copy of the state of the host application. The operations can also include responsive to receiving the first request, associating a snapshot identifier with the object identifier, and receiving a second request to modify a data item of the set of data items at the first set of physical address ranges. They can also include executing the second request by recording a modification a data item exclusively at a second set of physical address ranges and making the checkpoint copy by copying the set of data items of the snapshot from the first set of physical address ranges to a second memory device.
