Phase of Recovery (Log Shipping)

    Can anyone elaborate on the phases of recovery or point me to an article, for when you recover a database that has been log shipped? When Googling "Phases of Recovery Log Shipping" (I also tried Googling different variations of that string with no luck), I get a bunch of step-by-step articles on how to set up Log Shipping. I am interested in learning what goes on during that recovery.

    Thanks for any and all responses...

    Same as any other database, roll forward then roll back. With a log shipped database the roll back portion is only done when recovering the database, the roll forward is done after very log restore.

    Roll forward - transactions committed in the log, but not written to the data files are pushed there.

    Roll back - uncommitted transactions are undone from the data file.
