Does a normal transaction log backup initiate a checkpoint?

  • I can't seem to find a definitive answer to this. BOL says that a database backup will issue a checkpoint, but I am wondering if a transaction log backup will do the same, and commit active transactions to disk.

  • No it will not.

    No document references, was something that I tested some time back.

  • p.s. There are some circumstances where it will, but it's not something that happens always like with a database backup.
