Aurora Postgre SQL doesnt not have automated back up option

Hello,

I would like to inform you that Aurora backs up your cluster volume automatically and retains restore data for the length of the backup retention period. Aurora automated backups are continuous and incremental, so you can quickly restore to any point within the backup retention period. No performance impact or interruption of database service occurs as backup data is being written. You can specify a backup retention period from 1–35 days when you create or modify a DB cluster. Aurora automated backups are stored in Amazon S3.

Note:

• For Amazon Aurora DB clusters, the default backup retention period is one day regardless of how the DB cluster is created.
• You can't disable automated backups on Aurora. The backup retention period for Aurora is managed by the DB cluster.

Further I would like to inform that there is no option to perform Point in time restore using a manual snapshot, but you can perform a PITR by referring the steps mentioned in the below AWS documentation:

[+] Restoring a DB cluster to a specified time: https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/aurora-pitr.html

I sincerely hope this helps!
