# Database Backup Scripts
|
|
|
|
This directory contains scripts for backing up and restoring the PostgreSQL database.
|
|
|
|
## Prerequisites
|
|
|
|
- PostgreSQL client tools (`pg_dump`, `psql`) must be installed
|
|
- Environment variables must be set in `.env` or `.env.local`:
|
|
- `DATABASE_URL` - Local database connection string
|
|
- `REMOTE_DATABASE_URL` or `DATABASE_URL_PRODUCTION` - Remote database connection string
|
|
|
|
## Available Commands
|
|
|
|
### Backup Commands
|
|
|
|
```bash
|
|
# Backup local database
|
|
npm run db:backup:local
|
|
|
|
# Backup remote database
|
|
npm run db:backup:remote
|
|
|
|
# Sync remote database to local (backs up both, then restores remote to local)
|
|
npm run db:backup:sync
|
|
|
|
# List all backups
|
|
npm run db:backups
|
|
```
|
|
|
|
### Restore Commands
|
|
|
|
```bash
|
|
# Restore a specific backup (interactive - will show available backups)
|
|
npm run db:restore
|
|
|
|
# Restore to local database (default)
|
|
npm run db:restore ./backups/backup_file.sql.gz
|
|
|
|
# Restore to remote database (requires extra confirmation)
|
|
npm run db:restore ./backups/backup_file.sql.gz remote
|
|
```
|
|
|
|
### Direct Script Usage
|
|
|
|
You can also run the scripts directly:
|
|
|
|
```bash
|
|
# Backup operations
|
|
./scripts/backup-db.sh local
|
|
./scripts/backup-db.sh remote
|
|
./scripts/backup-db.sh sync
|
|
|
|
# Restore operations
|
|
./scripts/restore-db.sh <backup-file> [local|remote]
|
|
|
|
# List backups
|
|
./scripts/list-backups.sh [all|local|remote|recent]
|
|
```
|
|
|
|
## Backup Storage
|
|
|
|
All backups are stored in the `./backups/` directory with timestamps:
|
|
|
|
- Local backups: `local_YYYYMMDD_HHMMSS.sql.gz`
|
|
- Remote backups: `remote_YYYYMMDD_HHMMSS.sql.gz`
|
|
|
|
## Safety Features
|
|
|
|
1. **Automatic Backups**: The sync operation creates backups of both databases before syncing
|
|
2. **Confirmation Prompts**: Destructive operations require confirmation
|
|
3. **Extra Protection for Remote**: Restoring to remote requires typing "RESTORE REMOTE"
|
|
4. **Compressed Storage**: Backups are automatically compressed with gzip
|
|
5. **Timestamp Naming**: All backups include timestamps to prevent overwrites
|
|
|
|
## Common Use Cases
|
|
|
|
### Daily Local Development
|
|
|
|
```bash
|
|
# Start your day by syncing the remote database to local
|
|
npm run db:backup:sync
|
|
```
|
|
|
|
### Before Deploying Changes
|
|
|
|
```bash
|
|
# Backup remote database before deploying schema changes
|
|
npm run db:backup:remote
|
|
```
|
|
|
|
### Restore from Accident
|
|
|
|
```bash
|
|
# List recent backups
|
|
npm run db:backups
|
|
|
|
# Restore a specific backup
|
|
npm run db:restore ./backups/local_20240615_143022.sql.gz
|
|
```
|
|
|
|
## Environment Variables
|
|
|
|
You can set these in `.env.local` (git-ignored) for local overrides:
|
|
|
|
```bash
|
|
# Required for local operations
|
|
DATABASE_URL="postgresql://user:password@localhost:5432/dbname"
|
|
|
|
# Required for remote operations (one of these)
|
|
REMOTE_DATABASE_URL="postgresql://user:password@remote-host:5432/dbname"
|
|
DATABASE_URL_PRODUCTION="postgresql://user:password@remote-host:5432/dbname"
|
|
```
|
|
|
|
## Troubleshooting
|
|
|
|
### "pg_dump: command not found"
|
|
|
|
Install PostgreSQL client tools:
|
|
|
|
```bash
|
|
# macOS
|
|
brew install postgresql
|
|
|
|
# Ubuntu/Debian
|
|
sudo apt-get install postgresql-client
|
|
|
|
# Arch Linux
|
|
sudo pacman -S postgresql
|
|
```
|
|
|
|
### "FATAL: password authentication failed"
|
|
|
|
Check that your database URLs are correct and include the password.
|
|
|
|
### Backup seems stuck
|
|
|
|
Large databases may take time. The scripts show progress. For very large databases, consider using `pg_dump` directly with custom options.
