Permissions

IAM roles and permission

To use Google Cloud Storage as backup storage in the Xopero ONE service it's recommended that the GCS user has the Identity and Access Management (IAM) role of Storage Admin (roles/storage.admin - grants full control of buckets and objects) or create a service account with the minimal permission set:

• storage.objects.list

• storage.objects.get

• storage.objects.create

• storage.objects.delete

Find more details about permission on Google Cloud Storage official site.

Support for Immutable Storage

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

• s3:GetBucketObjectLockConfiguration - required to read Object Lock

• configuration.s3:GetBucketVersioning - required to read the versioning configuration.

Remember, that the Immutable Storage configuration is available only when creating the new bucket - there is no option to enable Immutable Storage in an already existing bucket!

Retention and/or versioning enabled for the bucket may result in the storage of additional data. It is recommended that the retention in Xopero ONE be longer than the one set for storage. Otherwise, it may lead to storage being overloaded!

There is no possibility to use the bucket with retention enabled as a storage for Xopero ONE.

It must be added to the Action section, and after the changes, the section must look like the below:

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