3. Possible Combinations Full  BULK_LOGGED doesn’t break automated backup procedures or log shipping. However, a log backup immediately before (when changing to Bulk Logged) and a log backup immediately after (when changing back to full) are recommended. Transitions to/from SIMPLE are NEVER recommended as they break the continuity of the log chain. This eliminates your ability to go back to a prior full…meaning you’re only as good as your last full backup! n/a Backup Log just prior to change Simple n/a No Change Required, Transaction Log Backup Recommended BEFORE B ulk_Logged No Change Required, Transaction Log Backup Recommended AFTER n/a Full SimpleBulk_LoggedFull From  To  Full Database or Differential backup after change Backup Log just prior to change Full Database or Differential backup after change
