Abstract: Methods and systems for restoring data are described. According to some embodiments, the method, in response to receiving a first restore request, initiates a second restore request to a hybrid data buffer to route blocks of backup data to the hybrid data buffer. The method further invokes an interrupt service routine (ISR) that is initialized with reserved addresses. When the blocks of backup data are transmitted to the hybrid data buffer, the method further tags, by the ISR, the blocks of backup data to a specified location, where the specified location is one of the reserved addresses.
