Log Backup Chain

If you break your log backup chain by switching a database into simple recovery or by executing BACKUP LOG WITH NO_LOG and WITH TRUNCATE_ONLY, there is a misconception that you then have to do a full backup in order to get your transaction log backups to run again.  This is incorrect.  Once you switch your recovery model back to full you only have to do a differential backup in order to restore the chain.

See Paul Randal’s blog post for more information (and an example script to demonstrate this).
