How do I configure Proxmox VE backups for disaster recovery?

import * as pulumi from "@pulumi/pulumi";
import * as aws from "@pulumi/aws";

// Create an S3 bucket to store Proxmox VE backups
const backupBucket = new aws.s3.Bucket("proxmox-backup-bucket", {
    versioning: {
        enabled: true,
    },
    serverSideEncryptionConfiguration: {
        rule: {
            applyServerSideEncryptionByDefault: {
                sseAlgorithm: "AES256",
            },
        },
    },
});

// Create an IAM role for Proxmox VE to access the S3 bucket
const backupRole = new aws.iam.Role("proxmox-backup-role", {
    assumeRolePolicy: aws.iam.assumeRolePolicyForPrincipal({ Service: "ec2.amazonaws.com" }),
});

// Attach a policy to the role to allow access to the S3 bucket
const backupPolicy = new aws.iam.RolePolicy("proxmox-backup-policy", {
    role: backupRole.id,
    policy: pulumi.output(backupBucket.arn).apply(arn => JSON.stringify({
        Version: "2012-10-17",
        Statement: [
            {
                Effect: "Allow",
                Action: [
                    "s3:PutObject",
                    "s3:GetObject",
                    "s3:ListBucket",
                ],
                Resource: [
                    arn,
                    `${arn}/*`,
                ],
            },
        ],
    })),
});

// Export the bucket name and IAM role ARN
export const bucketName = backupBucket.bucket;
export const roleArn = backupRole.arn;
