Zusammenfassung:A portion of a logical block address to physical block address ("L2P") translation map may be identified. A last snapshot of the portion of the L2P translation map may be identified. One or more write operations may be determined, where the write operations are associated with logical block addresses of the portion of the L2P translation map. The write operations may have been performed after the last snapshot of the portion of the L2P translation map was stored. An address on the portion of the L2P translation map may be updated by a processing device based on the determined one or more write operations and the last snapshot of the portion of the L2P translation map.
