Backup Tools Overview

The Backup Tools package provides enterprise-grade backup automation for Linux systems. Our scripts handle everything from scheduling to verification, with support for multiple storage destinations and encryption.

Main Scripts

1. backup-orchestrator.sh

The main backup management script:

# Interactive mode
./backup-orchestrator.sh

# CLI mode examples
./backup-orchestrator.sh --source /var/www --dest s3://my-bucket
./backup-orchestrator.sh --config /etc/backup-config.yml

Options:

--source        Source directory or files to backup
--dest          Destination (local path or cloud URL)
--compress      Compression method (gzip|bzip2|xz)
--encrypt       Enable encryption (requires GPG key)
--schedule      Cron schedule expression
--retention     Days to keep backups

2. backup-verify.sh

Verification and testing script:

# Test latest backup
./backup-verify.sh --latest

# Verify specific backup
./backup-verify.sh --file backup-2024-01-01.tar.gz

3. cloud-sync.sh

Cloud storage integration:

# Configure cloud storage
./cloud-sync.sh --setup aws|gcp|azure

# Manual sync
./cloud-sync.sh --sync-now /path/to/backups

Configuration

Example backup configuration:

# /etc/backup-config.yml
sources:
  - path: /var/www
    exclude:
      - "*.tmp"
      - "cache/*"
  - path: /etc
    exclude:
      - "*.log"

destinations:
  - type: local
    path: /mnt/backup-drive
  - type: s3
    bucket: company-backups
    prefix: production/

schedule:
  full: "0 0 * * 0"  # Weekly full backup
  incremental: "0 0 * * 1-6"  # Daily incremental

retention:
  full: 90  # days
  incremental: 14  # days

encryption:
  enabled: true
  key_id: "backup@company.com"

compression:
  method: gzip
  level: 6

notification:
  email: admin@company.com
  slack_webhook: https://hooks.slack.com/...

Common Use Cases

1. Website Backup

./backup-orchestrator.sh \
  --source /var/www \
  --source /etc/nginx \
  --source /etc/letsencrypt \
  --dest s3://backups/website \
  --compress gzip \
  --encrypt \
  --schedule "0 3 * * *"

2. Database Backup

./backup-orchestrator.sh \
  --type mysql \
  --databases "prod_db,staging_db" \
  --dest /mnt/backup-drive \
  --compress xz \
  --retention 30

3. Multi-Server Sync

./cloud-sync.sh \
  --source-server web1.company.com:/backups \
  --source-server web2.company.com:/backups \
  --dest s3://central-backup \
  --sync-schedule "*/15 * * * *"

Best Practices

1. Testing

   • Always verify backups after creation
   • Regularly test restore procedures
   • Keep offline copies of critical data

2. Security

   • Use strong encryption keys
   • Rotate keys periodically
   • Store keys securely and separately

3. Monitoring

   • Set up email notifications
   • Monitor backup sizes and timing
   • Check verification results

Troubleshooting

Common issues and solutions:

1. Backup Fails

   # Check logs
   ./backup-orchestrator.sh --check-logs
   
   # Test permissions
   ./backup-orchestrator.sh --test-permissions
   

2. Verification Errors

   # Detailed verification
   ./backup-verify.sh --verbose --file backup.tar.gz
   

3. Cloud Sync Issues

   # Test connectivity
   ./cloud-sync.sh --test-connection aws
