A system to protect data including a processor and a memory coupled to the processor to store instructions executable by a digital processing apparatus. The memory is operable to perform operations to protect stored data. The operations include receiving a write request for a current data input comprising input to be written to at least one monitored region of a storage volume, determining whether the current data input is a complete managed object and whether the current data input completes a previously deferred I/O operation and writing the current data input to a deferred storage device based on the determinations. Therefore, the system writes complete managed objects to the physical disk storage medium.
