Database backup best practices – Server Fault

For my current project, I’m using Aurora RDS and I’m looking for some advice on best practices in terms of backing up the database. My thought is to use AWS Backup to backup the database to 3 separate locations (one in the West Coast, US, one in the East Coast, US, and one in Europe) and keep the backups for 30 days. Is this a responsible backup strategy or should I have additional safeguards in place?
