Unsupported Action in Policy for S3 Glacier/Veeam

Hello,

New person using AWS S3 glacier and I ran across an issue. I am working with Veeam to add an S3 Glacier to my backup. I have the bucket created. I need to add the following to my bucket policy:

{
 "Version": "2012-10-17",
 "Statement": [
   {
     "Sid": "VisualEditor0",
     "Effect": "Allow",
     "Action": [
       "s3:DeleteObject",
       "s3:PutObject",
       "s3:GetObject",
       "s3:RestoreObject",
       "s3:ListBucket",
       "s3:AbortMultipartUpload",
       "s3:GetBucketVersioning",
       "s3:ListAllMyBuckets",
       "s3:GetBucketLocation",
       "s3:GetBucketObjectLockConfiguration",
       "ec2:DescribeInstances",
       "ec2:CreateKeyPair",
       "ec2:DescribeKeyPairs",
       "ec2:RunInstances",
       "ec2:DeleteKeyPair",
       "ec2:DescribeVpcAttribute",
       "ec2:CreateTags",
       "ec2:DescribeSubnets",
       "ec2:TerminateInstances",
       "ec2:DescribeSecurityGroups",
       "ec2:DescribeImages",
       "ec2:DescribeVpcs",
       "ec2:CreateVpc",
       "ec2:CreateSubnet",
       "ec2:DescribeAvailabilityZones",
       "ec2:CreateRoute",
       "ec2:CreateInternetGateway",
       "ec2:AttachInternetGateway",
       "ec2:ModifyVpcAttribute",
       "ec2:CreateSecurityGroup",
       "ec2:DeleteSecurityGroup",
       "ec2:AuthorizeSecurityGroupIngress",
       "ec2:AuthorizeSecurityGroupEgress",
       "ec2:DescribeRouteTables",
       "ec2:DescribeInstanceTypes"
     ],
     "Resource": "*"
   }
 ]
}

Once I put this in, the first error I get is "Missing Principal". So I added "Principal": {}, under SID. But I have no idea what to put in the brackets. I changed it to "*" and that seemed to fix it. Not sure if this the right thing to do?

The next error I get is for all the EC2's and s3:ListAllMyBuckets give me an error of "Unsupported Action in Policy". This is where I get lost. Not sure what else to do. Do I need to open my bucket to public? Is this a permissions issue? Do I have to recreate the bucket and disable object-lock?

Please help.
