Problem Scenario :

One of our customers reported Production database has been corrupted, needs to back-up and restore database with a different name in the same RDS. But it’s not possible in the AWS RDS if we try to restore will get the below error.

Limitations :

Database <database_name> cannot be restored because there is already an existing database with the same family_guid on the instance

You can’t restore a backup file to the same DB instance that was used to create the backup file. Instead, restore the backup file to a new DB instance.

Approaches to Backup and Restore :

Option 1:

1.Import and Export into same RDS instance

The database is corrupted so we can’t proceed with this step

Option 2:

2. Backup and restore into different RDS using S3

2.1.Backup from production RDS Instance

exec msdb.dbo.rds_backup_database

@source_db_name=’selva’,

@s3_arn_to_backup_to=’arn:aws:s3:::mmano/selva.bak’,

@overwrite_S3_backup_file=1,

@type=’FULL’;
