Non-Immutable Buckets
Use the following JSON for non-immutable buckets to create an IAM Policy. These permissions will allow the Veeam Backup Service to access the S3 repository to save/load data to/from an object repository.
Starting with Veeam Backup & Replication 11a, the ListAllMyBuckets permission is not required if you manually enter the bucket name on the Bucket step of the New Object Repository wizard.
Note: Replace yourbucketname (lines 16 and 17) with the actual bucket name.
