If a lock is set to expire in one hour for example, then it will renew in 30 minutes. Single execution jobs locks have a hard coded timeout of 30 minutes. That value is completely arbitrary. I did not want a value to small resulting in lots of lock renewal queries. Repepating job lock timeouts are based on the job interval. The timeout is 25% more than the interval. The compression job runs every two hours, so the lock timeout will be 2.5 hours and will renew in 75 minutes.
