SIMPLE: Uses full or differential copies of the database. Truncates the transaction logs automatically. Does not backup the transaction log file(s). Changes made after the last backup cannot be restored (they are lost).

FULL: Includes both database and transaction log backups. The transaction logs must be manually truncated. Recovery can be don to a specific point in time. Only transactions in process at the time of the backup will be lost (those that are rolled back).

BULK: Includes both database and transaction log backups, but individual transaction data is not logged for bulk transactions. Transaction logs must be truncated manually. Restore cannot be done to a specific point in time.
