When your database is damaged and you are trying to do a last-ditch backup of the log before starting restoring over it, or when for other reasons you're restoring or moving a DB and want to ensure that no transactions are lost.

It's a backup log command. WITH NO_TRUNCATE if the log is damaged, with NO_RECOVERY if it's not.

you would use the norecovery option on a log backup when you want to swap primary and secondary roles in a logshipping set up without needing to reinitialise from a full backup.

This sounds like a series of interview questions. My recommendation is that Gail's good answer has given you the end result but you need to readup about backups and TailLog backups in Books Online. Just in case you don't know what "Books Online" is, open SSMS then press the {f1} key and you're there (is the SQL Server "help" system).

RBAR is pronounced ree-bar and is a Modenism for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
Stop thinking about what you want to do to a row... think, instead, of what you want to do to a column.
If you think its expensive to hire a professional to do the job, wait until you hire an amateur. -- Red Adair
