Identifying AWS Backup Snapshot Sizes

Question

Hello all, We regularly create RDS snapshots and AWS S3 snapshots using the AWS Backup service. Could you please advise on how to identify and determine the size of these snapshots? While exploring the Cost Explorer, I couldn't find specific options for this purpose. Are there alternative methods or procedures to effectively identify the size of AWS Backup snapshots pls? Thanks.

I also find these two Blog posts helpful with figuring out what portion of backups are included in your RDS Costs.

Answer

Here are three ways that might be of help - -

1. Use Cost Explorer's custom reports:
- Create a custom report with the cost category as "Backup Storage" to view AWS Backup storage costs.
- This can give you an idea of the total storage being used, though doesn't show individual snapshot sizes.

2. Use the AWS Backup console:
- Go to the Backups section and select the backup plan you want to check. 
- This will show a list of all backups created by that plan. 
- You can see the storage size for each individual backup in that list.

3. Use the AWS CLI:
- Run `aws backup list-backup-jobs` to list all backup jobs. 
- Note down the backup job ID for the snapshots you want to check.
- Then run `aws backup describe-backup-job --backup-job-id ` to see details on an individual backup, including the storage size.
