活动SQL Server 2005数据库的最后修改日期(Last modification date for a live SQL Server 2005 database)

有没有办法知道在活动SQL Server 2005数据库中最后一次写入操作发生的时间？

我目前在我的服务器上有30个（和不断增长的）数据库。其中只有一些会看到日常活动（但哪些日常活动会随着时间的推移而变化）。我的备份空间有限，我希望每日备份所有“自上次备份后修改”的数据库。

事实上，我在问这个问题的反面。我不想从备份中询问最后一次写入日期以查看是否应该恢复它，而是要告诉最后写入数据库的日期以查看是否应备份它。

由于备份在服务器上运行，我可以检查日志的最后修改时间，但这不是很干净，也不确定是完全可靠的。

Is there a way to know when the last write operation has occurred in a live SQL Server 2005 database?

I currently have 30 (and growing) databases on my server. Only some of these see daily activity (but which ones get daily activity varies over time.) My backup space is limited and I'd like to do a daily backup of all "modified since last backup" databases.

In fact, I'm asking the reverse of this question. Instead of asking last write date from a backup to see if I should restore it, I want to tell last write date of a live database to see if I should back it up.

Since the backups run on the server itself, I could check the last modification time of the log, but that isn't very clean, nor I'm sure is totally reliable.
