SQL Server：如何查询上次事务日志备份的时间？

Question

我想查询所有数据库（在 SQL Server 2008 实例中）的最后一次事务日志备份的日期。怎么做？我知道这些信息在某个地方，但我不知道在哪里。

Answer 1

SELECT   d.name,
         MAX(b.backup_finish_date) AS backup_finish_date
FROM     master.sys.sysdatabases d
         LEFT OUTER JOIN msdb..backupset b
         ON       b.database_name = d.name
         AND      b.type          = 'L'
GROUP BY d.name
ORDER BY backup_finish_date DESC

Answer 2

我建议使用这个修改后的脚本，这样您就可以看到哪个数据库处于 FULL 或 BULK_LOGGED 恢复模式并且没有任何 LOG BACKUP。

SELECT   d.name,
         d.recovery_model_desc,
         MAX(b.backup_finish_date) AS backup_finish_date
FROM     master.sys.databases d
         LEFT OUTER JOIN msdb..backupset b
         ON       b.database_name = d.name
         AND      b.type          = 'L'
GROUP BY d.name, d.recovery_model_desc
ORDER BY backup_finish_date DESC
