ABSTRACT:
A method for data storage includes accepting write commands belonging to a storage operation invoked by a host computer, and caching the write commands in a volatile memory that is powered by external electrical power. A current execution status of the storage operation is also cached in the volatile memory. Responsively to an interruption of the external electrical power during the storage operation, the cached write commands and the cached execution status are backed up in a non-volatile memory. Upon resumption of the external electrical power, the backed up execution status is recovered, so as to resume the interrupted storage operation.
