+# 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.
