Abstract
An apparatus includes an interface and a processor. The interface is configured to communicate with a non-volatile memory. The processor is configured to hold a translation table that maps between logical addresses and respective physical addresses in the non-volatile memory, to back-up to the non-volatile memory a baseline version of the translation table in one or more bulks, to additionally back-up to the non-volatile memory one or more incremental updates, which specify changes relative to the baseline version of the translation table caused by subsequent storage operations, to determine a maximal number of the incremental updates that, when recovered together with the baseline version from the non-volatile memory and replayed in the processor, meets a target recovery time of the translation table, and to set a number of the backed-up incremental updates to not exceed the maximal number.
