]]> Comment on SQL University: Backups and Restores – Recovery Models by Paul Randal http://www.sqlps.com/blog/archive/2009/10/sql-university-backups-and-restores-recovery-models/comment-page-1/#comment-90 Paul Randal Wed, 07 Oct 2009 16:31:45 +0000 http://www.sqlps.com/blog/?p=145#comment-90 Couple of clarifications: 1) the amount of transaction log generated in the SIMPLE and BULK_LOGGED recovery models is exactly the same. Only difference is that the log can be cleared (if possible) on a checkpoint, rather than waiting for a log backup. The log space can only be marked as unused once an entire VLF doesn't contain any active log records, not just because the data pages that the log records affected have been written to the data files. 2) minimally-logged operations do generate transaction log in the BULK_LOGGED recovery model, just not anywhere near as much as when fully-logged 3) point-in-time recovery is available in the BULK_LOGGED recovery model, but not at any point in a log backup that contains a minimally-logged operation. 4) in any recovery model, it's not just a checkpoint or log backup that says when transaction log records are no longer required - you need to consider database mirroring send queues, transactional replication log reader, change data capture, *other* active transactions preventing log records from committed transactions being overwritten. You can find a good primer on log architecture and recovery model behavior in the TechNet Magazine article I wrote on Understanding Logging and Recovery in SQL Server: http://technet.microsoft.com/en-us/magazine/2009.02.logging.aspx Thanks Couple of clarifications:

You'll also receive notification if the default database or language is changed for those logins, if the login is disabled or enabled, etc. Basically, any changes that you might make on the General or Status pages of the Login Properties in SSMS will fire this trigger.
