You are running a mission-critical DB app in OCI. You take regular backups of your DB system to OCI object storage. Recently, you notice a failed db backup status in the console. What 2 steps can you take to determine the cause of the backup failure?
1) Ensure the database archiving mode is set to NOARCHIVELOG
2) Ensure that your database host can connect to the OCI object storage
3) Restart the dcsagent program if it has a status of stop or waiting
4) Make sure that the database is not active and running while the backup is in progress
