AWS S3

This article outlines the minimum permissions needed to use an AWS S3 bucket as backup storage for Xopero ONE. The policies below enable you to integrate your AWS S3 storage with Xopero ONE.

AWS bucket policy

The bucket that will be used to store the data must have the following policy (JSON) assigned:

{
     "Version": "2012-10-17",
     "Statement": [
          {
               "Effect": "Allow",
               "Principal": {
                    "AWS": "arn:aws:iam::{account}:user/backup-user"
          },
               "Action": [
                    "s3:ListBucket",
                    "s3:GetObject",
                    "s3:PutObject",
                    "s3:DeleteObject"
                
               ],
               "Resource": [
                    "arn:aws:s3:::bucket-name",
                    "arn:aws:s3:::bucket-name/*"
               ]
          }
     ]
}

Support for immutable storage

Remember that immutable storage configuration is available only when creating a new bucket— there is no option to enable it for an existing bucket.

Enabling retention and/or versioning for the bucket may result in additional data being stored— it is recommended that the retention period in Xopero ONE be longer than the one set for the storage. Otherwise, this may lead to storage overload.

If you want to use immutable storage, the following permissions are required:

Required to read Object Lock configuration

s3:GetBucketObjectLockConfiguration

Required to read the versioning configuration

s3:GetBucketVersioning

It must be added to the Action section, and after the changes, the section should look as shown below:

"Action": [
                    "s3:ListBucket",
                    "s3:GetObject",
                    "s3:PutObject",
                    "s3:DeleteObject",
		    "s3:GetBucketVersioning",
	            "s3:GetBucketObjectLockConfiguration"
               ],
