Backups

extras/backup/ backs up service configs to S3-compatible storage (e.g., DigitalOcean Spaces) using restic. Safely snapshots SQLite databases before backup.

Setup

# Install dependencies
apt install -y restic sqlite3

# Configure
cd extras/backup
cp .env.example .env   # fill in your S3 credentials, restic password, and backup path

# Initialize restic repo (once)
set -a && source .env && set +a
restic init

# Test a backup
./backup-config.sh

# Schedule daily at 3 AM
(crontab -l 2>/dev/null; echo "0 3 * * * $(pwd)/backup-config.sh >> /var/log/restic-backup.log 2>&1") | crontab -

Restore

cd extras/backup
set -a && source .env && set +a
restic snapshots                             # list snapshots
restic restore latest --target /tmp/restore  # restore latest

What It Does

• Snapshots all SQLite .db files to .db.bak before backing up (prevents corruption)
• Excludes live database files and journals (only the safe .bak copies are backed up)
• Prunes old snapshots: keeps 7 daily, 4 weekly, 3 monthly
• Cleans up .bak files after backup completes
