주의

Periodically, and on certain user-directed actions, Microsoft SQL Server forces a write of dirty pages, ensuring data integrity at a point in time. The recovery interval option configures periodic dirty page writes. The Transact-SQL statement CHECKPOINT and other user-directed actions, such as initiating a complete database backup, force a dirty page write.

If TRUE, SQL Server removes log entries referencing committed transactions when activity on the database forces a dirty page write.

If FALSE, the forced dirty page writes have no effect on the database transaction log.

중요 정보중요

Setting the TruncateLogOnCheckpoint property to TRUE implies that backup-maintained database integrity relies on backup of the database only. If TRUE, you cannot back up a database transaction log, and backup strategies based on differential backup of the log are not available. For more information, see 데이터베이스 옵션 설정.
