SELECTIVE CONTROL FOR COMMIT LINES FOR SHADOWING DATA IN STORAGE ELEMENTS

摘要

Systems and methods to selectively apply commit and rollback operations between a backup memory and a primary memory are implemented. For each entry in the primary memory, a monitor may be implemented to track the state of the entry. The state may indicate that the entry has changed upon execution of a write command for the entry. The state may be reset upon execution of a commit or rollback command. The primary memory may be a storage array coupled to a backup memory. The backup memory may be a shadow storage element.
