摘要
Data recovery in a database includes performing a backward scan of a transaction log that records transactions made on the database. The backward scan includes traversing log records starting from a latest-in-time log record toward the beginning of the transaction log. Each log record can be replayed to recover data for a database row associated with the log record. An earlier-in-time log record is skipped if the associate database row has been recovered by later-in-time log record.
