Abstract
A system and method is presented for database restoration in a distributed data system. The distributed data system has a first database on a first server which needs restoration. The first database is first restored with a predetermined full backup file, the full backup file being made at a first predetermined time. The first database is then restored with one or more incremental backup files, the incremental backup files being made since the first predetermined time and having the most recent backup file made at a second predetermined time. A transaction log documenting data transactions since the second predetermined time is then examined. One or more transactions listed in the transaction log after the second predetermined time are then executed since they are not included in the incremental backup files. To verify whether the restored first database has completed its restoration, a transitive vector of the first database is compared with a transitive vector of a second database on a second server of the distributed database system, wherein the second database and the restored first database are expected to be the same.
