This solution includes a directory structure and automated Bash scripts for backups using rsync and tar. It integrates MinIO for S3-like storage and uses AWS CLI for easy recovery. It also features multi-server deployment with Ansible, an API, and a Vue.js frontend, all tested and deployable in cloud or on-premises setups.

Phase 1: Backup Solution Setup

[ ] Step 1: Set Up Backup Directories and Scripts

[ ] Identify critical directories for backup (e.g., application data, databases, config files).
[ ] Create a root directory for backups with subdirectories for daily, weekly, and monthly backups.
```
  mkdir -p /opt/backup/{daily,weekly,monthly}
```
[ ] Verify directory structure creation.

[ ] Step 2: Create Automated Backup Script

[ ] Write a Bash script to automate file backups using rsync or tar.

  # Example backup script
  #!/bin/bash
  SRC_DIR="/var/www"
  BACKUP_DIR="/opt/backup/daily"
  DATE=$(date +'%Y-%m-%d')
  rsync -a --delete $SRC_DIR $BACKUP_DIR/$DATE
  tar -czvf $BACKUP_DIR/backup-$DATE.tar.gz $SRC_DIR
  echo "Backup completed for $DATE."

[ ] Schedule script execution using cron for daily, weekly, or monthly backups.
```
  crontab -e
  0 2 * * * /bin/bash /opt/backup/backup.sh
```

Phase 2: MinIO Setup and Integration

[ ] Step 3: Install and Configure MinIO as an S3 Alternative

[ ] Install MinIO on Manjaro.
```
  sudo pacman -S minio
```
[ ] Start MinIO on localhost (port 9000).
```
  minio server /data/minio
```

[ ] Configure AWS CLI for MinIO and set endpoint.

  aws configure --profile minio
  aws configure set profile.minio.s3.endpoint_url http://localhost:9000

[ ] Create a backup bucket in MinIO.

  aws --profile minio s3 mb s3://my-smb-backups

[ ] Step 4: Update Backup Script to Sync with MinIO

[ ] Modify the backup script to upload backups to MinIO after creation.

  aws s3 cp "$BACKUP_DIR/backup-$DATE.tar.gz" "s3://$BUCKET_NAME/daily/" \
      --endpoint-url "$MINIO_ENDPOINT" \
      --profile minio

[ ] Test syncing to MinIO and verify backup files.

Phase 3: Database Backup Integration (Optional)

[ ] Step 5: Add Database Backup Support

[ ] Modify the backup script to support database backups (MySQL, PostgreSQL).

MySQL:

  mysqldump -u root -p'my_password' mydatabase > $BACKUP_DIR/daily/mydatabase-$DATE.sql

PostgreSQL:

  pg_dump mydatabase > $BACKUP_DIR/daily/mydatabase-$DATE.sql

[ ] Automate sync of database backups to MinIO.

  aws s3 cp $BACKUP_DIR/daily/mydatabase-$DATE.sql s3://$BUCKET_NAME/daily/ --profile minio

Phase 4: Disaster Recovery

[ ] Step 6: Create Disaster Recovery Script

[ ] Write a restore script to retrieve and extract backups from MinIO.

  aws s3 cp "s3://$BUCKET_NAME/daily/backup-$DATE.tar.gz" "$DOWNLOAD_DIR" \
      --endpoint-url "$MINIO_ENDPOINT" \
      --profile minio
  tar -xzvf "$DOWNLOAD_DIR/backup-$DATE.tar.gz" -C "$RESTORE_DIR"

[ ] Verify functionality by performing a test restore.

Phase 5: Multi-Server Deployment with Ansible

[ ] Step 7: Automate Solution Deployment with Ansible

[ ] Create an Ansible playbook for deploying the backup solution to multiple servers.

  - hosts: all
    become: yes
    tasks:
      - name: Install AWS CLI
        package:
          name: aws-cli
          state: present

[ ] Test playbook to verify it deploys backup scripts and schedules cron jobs on target servers.

Phase 6: Backend Development

[ ] Step 1: Set Up Python Environment with VirtualFish

[ ] Create and activate a virtual environment with VirtualFish.
```
  vf new backup-api
  vf activate backup-api
```

[ ] Step 2: Install Flask and Dependencies

[ ] Install Flask and other dependencies within the virtual environment.
```
  pip install Flask Flask-RESTful flask-cors
```

[ ] Step 3: Configure Project Structure and Implement API

[ ] Set up project structure.

  mkdir -p project/app
  touch project/main.py project/app/__init__.py project/app/routes.py project/app/backup_utils.py

[ ] Step 4: Define Routes and Backup Logic

[ ] Implement backup, restore, and list-backups endpoints in app/routes.py.

Example route:

  @backup_blueprint.route('/backup', methods=['POST'])
  def backup():
      result = create_backup()
      return jsonify(result), 200

[ ] Implement backup and restore logic in app/backup_utils.py.

Phase 7: Frontend Development

[ ] Step 1: Set Up Vue.js Project

[ ] Create a Vue.js project for the frontend.

  npm install -g @vue/cli
  vue create backup-ui
  cd backup-ui

[ ] Step 2: Implement Frontend Interface

[ ] Design App.vue and BackupDashboard.vue for backup, restore, and listing backups.
```
  <button @click="createBackup">Create Backup</button>
```

[ ] Step 3: Connect Frontend to Backend API

[ ] Set up Axios or Fetch to interact with the Flask API.
[ ] Verify communication between frontend and backend.

Final Phase: Testing and Deployment

[ ] Step 1: Testing

[ ] Test backup and restore functionality thoroughly, including database and MinIO sync.
[ ] Test deployment across multiple servers.

[ ] Step 2: Deployment

[ ] Deploy the solution on a cloud platform or on-premises for production use.
[ ] Monitor and optimize for performance and reliability.

Note: Each phase may require additional testing and modifications. Document any changes to scripts and configurations.
