Backup database configuration safely

Create a backup of current database configuration

Safely experimenting with different database providers while preserving the current proven configuration

• · .env file with current database credentials
• · Optional timestamp validation

• · .env.backup file with timestamp
• · Restoration guidance and backup location info
• · Backup integrity validation

• · Read/Write (.env, .env.backup)
• · Bash (cp with timestamps, git ignore verification)

• · .env file exists with database configuration
• · .gitignore configured to exclude .env* files

• · .env file not found or not readable
• · Permission denied when writing .env.backup
• · .env file is empty or malformed

• · Preserves all database env vars (Turso/Supabase credentials)
• · Timestamps backups for versioning
• · Maintains file permissions (readable only by owner)
• · Auto-excludes from git (respects .gitignore)
• · Provides restoration guidance with backup location
