Abstract
Embodiments of systems and methods that ensure integrity of data during unexpected power interruption of loss are disclosed. In some embodiments, critical data is saved quickly and efficiently using backup power. Data integrity is ensured even when the reliability of backup power sources is an issue. In some embodiments, by skipping the updating and saving of system data while operating on backup power, significant reduction of time for saving critical data can be achieved. System data can be restored next time the data storage system is restarted. Improvements of data storage system reliability are thereby attained.
