Daily Backup with Retention Period for SQL Server on Amazon Linux

Question

I would like to take a baily backup with 7 days retention period for SQL Server DB which installed on Amazon Linux EC2 instance.

I tried the below two scenarios with no luck:

1. -RetentionDays
2. The below script: EXEC sp_configure 'show advanced options', 1;
   GO
   RECONFIGURE;
   GO
   EXEC sp_configure 'media retention', 1;
   GO
   RECONFIGURE;
   GO
