Scheduled Restart and Backup restart at same time

If a user's scheduled restart and scheduled backups eventually execute at the same time a perfect storm can occur and cause the server to not start back up properly. crafty would lose the server's PID.

We need to check on a restart to make sure the server is not currently backing up with the shutdown for backup duration option checked.

We cannot recreate this, but we have sufficient evidence in logs to determine this is true.
