AWS Backup Options
Hello,
Please see attached screenshot. Here is a Dropbox link https://www.dropbox.com/scl/fi/212czafqcjp8id2qrkmnk/AWS-Backup.pdf?rlkey=dn229dald3y49sagfu8b400el&dl=0
I have set up an AWS Backup for an S3 Bucket and have enabled:
- Daily Backups
- Continuous Backups
- Copy to destination: different region than the S3 source region
The help info reads,
Amazon RDS does not support cross-Region or cross-account copies of continuous backups because log copies are not supported. If you want to use cross-Region or cross-account copies, use AWS Backup to copy your Amazon RDS snapshots instead.
I read somewhere that if you enable cross-Region backups it will convert the continuous backups to snapshots, but I am not sure of this is the case. I also read that snapshots are default to 1 hour. the information gets a bit vague in this area.
I believe the following results may be true. If not, please let me know where I am misunderstanding the process...
Daily Backups Virgina & N California:
- Every day at 2am MST
- 120 day retention
Continuous Backups Virginia Only:
- within 1 second of precision
- 35 day retention
Snapshot Backups N California Only:
- Once an hour
- 120 day backup
Are these the correct results? Are all of these backups incremental? I hope so otherwise the cost could become significant.
Thank you of your help!

Hello.
Are these the correct results?
Yes, I think this is the correct result.
Are all of these backups incremental?
I think RDS snapshots are incremental copies even if they are snapshot copies between regions.
https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_CopySnapshot.html#USER_CopySnapshot.AcrossRegions.Full
Regarding continuous backup, the first backup is a full backup, and after that, it works by continuously backing up the database transaction log.

I read somewhere that if you enable cross-Region backups it will convert the continuous backups to snapshots, but I am not sure of this is the case. I also read that snapshots are default to 1 hour. the information gets a bit vague in this area.
Perhaps you have read the following part of the document below?
https://docs.aws.amazon.com/aws-backup/latest/devguide/point-in-time-recovery.html
Creating copies of Amazon RDS continuous backups — You can't create copies of Amazon RDS continuous backups because AWS Backup for Amazon RDS does not allow copying transaction logs. Instead, AWS Backup creates a snapshot and copies it with the frequency specified in the backup plan.

The screenshot I posted via rePost wasn't being processed. Can you take a look at this and let me know if you feel the same? Here's the dropbox link https://www.dropbox.com/scl/fi/212czafqcjp8id2qrkmnk/AWS-Backup.pdf?rlkey=dn229dald3y49sagfu8b400el&dl=0
I checked the image. I think the settings themselves are correct.
