RDS Continuous Backup Pricing for PITR

Hi, the PITR costs are a combination of 2 elements: when needed, the cost of the snapshot(s) from which you start the PITR and the size-related cost of transaction logs that need to be accumulated to reach your desired point of recovery.

Those various costs and how they combine with each other are highly detailled in this blog post: https://aws.amazon.com/blogs/database/demystifying-amazon-rds-backup-storage-costs/

Please, give it a detailled read to get all the information that you need to compute your own costs.

Best,

Didier
