DynamoDB Backup IAM Role Permissions
Veeam Backup for AWS uses DynamoDB Backup IAM roles to perform the following operations:
- To enumerate resources added to a backup session.
- To create backups of DynamoDB tables.
- To create backup copies, and so on.
To perform these operations, IAM roles specified in the DynamoDB backup settings must meet the following requirements:
- The AWS Backup service must be granted permissions to assume the IAM roles.
To allow the AWS Backup service to assume an IAM role, configure trust relationships for the role and add the following statement to the trust policy:
{ "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": "sts:AssumeRole", "Principal": { "Service": "backup.amazonaws.com" } } ] } |
To learn how to configure trust relationships, see Before You Begin.
- The IAM roles must be granted the following permissions:
- IAM roles specified in the backup policy settings:
{ "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": [ "backup:CopyFromBackupVault", "backup:CopyIntoBackupVault", "backup:DeleteRecoveryPoint", "backup:DescribeBackupJob", "backup:DescribeCopyJob", "backup:DescribeRecoveryPoint", "backup:DescribeRegionSettings", "backup:ListBackupVaults", "backup:ListRecoveryPointsByBackupVault", "backup:ListTags", "backup:StartBackupJob", "backup:StartCopyJob", "backup:StopBackupJob", "backup:TagResource", "backup:UntagResource", "backup:UpdateRegionSettings", "dynamodb:DescribeContinuousBackups", "dynamodb:DescribeTable", "dynamodb:DescribeTimeToLive", "dynamodb:ListTables", "dynamodb:ListTagsOfResource", "dynamodb:StartAwsBackupJob", "ec2:DescribeRegions", "events:DeleteRule", "events:DescribeRule", "events:ListTargetsByRule", "events:PutRule", "events:PutTargets", "events:RemoveTargets", "iam:GetContextKeysForPrincipalPolicy", "iam:GetRole", "iam:ListAccountAliases", "iam:PassRole", "iam:SimulatePrincipalPolicy", "kms:Decrypt", "sns:CreateTopic", "sns:DeleteTopic", "sns:ListSubscriptionsByTopic", "sns:ListTopics", "sns:SetTopicAttributes", "sns:Subscribe", "sns:Unsubscribe", "sqs:CreateQueue", "sqs:DeleteMessage", "sqs:DeleteQueue", "sqs:ListQueues", "sqs:ReceiveMessage", "sqs:SetQueueAttributes" ], "Resource": "*" } ] } |
- IAM roles used to perform backup operations manually as described in section Creating DynamoDB Backups Manually:
{ "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": [ "backup-storage:MountCapsule", "backup:CopyFromBackupVault", "backup:CopyIntoBackupVault", "backup:CreateBackupVault", "backup:DeleteBackupVault", "backup:DeleteRecoveryPoint", "backup:DescribeBackupJob", "backup:DescribeCopyJob", "backup:DescribeRecoveryPoint", "backup:DescribeRegionSettings", "backup:ListBackupVaults", "backup:ListTags", "backup:StartBackupJob", "backup:StartCopyJob", "backup:StopBackupJob", "backup:TagResource", "backup:UntagResource", "backup:UpdateRegionSettings", "dynamodb:DescribeContinuousBackups", "dynamodb:DescribeTable", "dynamodb:DescribeTimeToLive", "dynamodb:ListTagsOfResource", "dynamodb:StartAwsBackupJob", "ec2:DescribeRegions", "iam:GetContextKeysForPrincipalPolicy", "iam:GetRole", "iam:PassRole", "iam:SimulatePrincipalPolicy", "kms:Decrypt", "kms:DescribeKey" ], "Resource": "*" } ] } |
