Impact of stopping AWS Backup
Issue I was facing
We are saving company data to S3 → Implementing daily S3 backups with 7-day retention using AWS Backup, but we are concerned about increasing costs. I'm wondering if it's okay to reduce the frequency of AWS Backup or stop it completely.
Please let me know what impact there would be if AWS Backup is stopped.
Answer
Stopping AWS Backup will not affect the data in your S3 bucket or the bucket configuration.
After checking the official documentation, I did not find any statements indicating otherwise.
Therefore, you can consider that there will be no impact.
If versioning is enabled on S3 buckets, S3 versioning creates version information for each object, and if you accidentally delete an object, you can restore it by reverting to the previous version.
Alternative S3 cost reduction options
Rather than reducing AWS Backup costs, it would be more appropriate to review the storage classes of the S3 bucket that is being backed up and remove unnecessary objects from the bucket.
For S3 cost reduction methods, please refer to this repost article [1].
While AWS Backup doesn't have features that directly reduce costs, you can optimize costs by adjusting backup frequency and retention periods.
Information about AWS Backup cost optimization can be found in the following document [2].
