Amazon S3 buckets for Server Backup storage

Before you set up Server Backup storage in the Management Console, you must create at least one Amazon S3 bucket in your AWS account for Server Backup storage. An S3 bucket that is used for Server Backup storage should not be used for any other workloads.

Requirements and recommendations for S3 buckets for Server Backup are listed below. During the storage setup, each S3 bucket is validated to ensure that it meets all requirements and can be accessed by Server Backup agents. Validation fails if an S3 bucket does not have the required settings. Validation does not fail if an S3 bucket does not have the recommended settings.

Amazon S3 bucket requirements and recommendations

Amazon S3 bucket characteristic or property	Value	Required or recommended
AWS Region	Any region in the aws partition	Required
Bucket Name	Any name that complies with Amazon S3 bucket naming rules	Required
Object Ownership	ACLs disabled	Recommended
Block Public Access	Block all public access	Recommended
Bucket Versioning	Enabled	Required
Object Lock	Enabled	Required
Requester pays	Disabled	Required

We do not recommend enabling an Intelligent-Tiering rule for an S3 bucket for Server Backup data. If an S3 bucket has an Intelligent-Tiering rule (for example, moving data to Amazon S3 Glacier storage in 30 days instead of the default of 90), validation will fail for the S3 bucket.

We recommend adding one S3 bucket for each physical region that you support. For example, you could add one bucket in the United States, and one bucket in Europe. Multiple customers can back up data to the same S3 bucket, but each customer can only access their own data.
