Abstract
A captured sequence of log records for a copy of a database may be inspected to identify an obviating log record at a captured sequence position of the captured sequence and related to a page of the plurality of pages, the obviating log record corresponding to an obviating change that replaces an earlier change of an earlier log record. The captured sequence of log records may be sorted into an applied sequence of log records for applying changes of the sequence of changes, in which the obviating log record is moved from the captured sequence position to an applied sequence position that is prior to the earlier sequence position of the earlier log record. The database may then be recovered using the applied sequence of log records.
