🚨 Disaster Recovery Plan (DRP)

📋 Prerequisites

1. New Linode Instance (Ubuntu 22.04).
2. Linode Object Storage Access Keys (Access/Secret).
3. Cloudflare Tunnel Token.

🏃 Recovery Steps

1. Install Docker & Rclone

curl -fsSL [https://get.docker.com](https://get.docker.com) -o get-docker.sh && sh get-docker.sh
sudo apt install rclone -y

2. Configure Storage & Pull Backups

Configure rclone config to point to linode-s3. Then pull the latest data:

mkdir -p /opt/docker/backups/recovery
rclone copy linode-s3:davisdre-backups-chicago/daily /opt/docker/backups/recovery --latest-only

3. Restore Global Database

Start the global-db container with an empty volume. Restore the SQL dump:

gunzip -c /opt/docker/backups/recovery/postgres_full_DATE.sql.gz | docker exec -i global_postgres psql -U postgres

4. Restore App Files

Extract the application data to their respective folders:

# Note: Ensure the paths in the tar match your /opt/docker structure
tar -xzf /opt/docker/backups/recovery/app_files_DATE.tar.gz -C /

5. Launch Services

cd /opt/docker/dashboard && docker compose up -d
cd /opt/docker/gitea && docker compose up -d
cd /opt/docker/linkwarden && docker compose up -d
cd /opt/docker/freshrss && docker compose up -d
cd /opt/docker/memos && docker compose up -d
