bulk logged insertion

  • Yanum_Vlad (9/25/2016)


    Dear all,

    I still do not catch, how Full (!) log backup works when Bulk Minimal logging is in place.

    BOL states:

    Under the bulk-logged recovery model, if a log backup covers any bulk operations, the log backup contains both log records and the data pages that were changed by bulk operations.

    There's no such thing as a "Full log backup", log backups are log backups, the BoL entry is correct about how log backups work in bulk-logged recovery when there are minimally logged operations

    But what about Full recovery model?

    There are no minimally-logged operations in full recovery model, log backups only contain log records as all operations are fully logged

    https://msdn.microsoft.com/en-us/library/ms190203.aspx

    What does mean #4 there?

    Not sure what part of that page you're referring to.

    As for me, I would really make full / deferential backup to ensure no data loss.

    There is no need to take a full/diff backup after switching from Bulk-logged to Full recovery. A log backup is a good idea, and if you're worried about the inability to recovery, a log backup is all you need.

    p.s. 7 year old thread (with a lot of incorrect statements in it), if you have a question, a new thread is preferred.
