Cloudflare DNS Backup

Automated Bash script that backs up every DNS record across all your Cloudflare zones via the API. Exports to timestamped JSON files — run it before DNS changes, on a daily cron, or after incidents to maintain a recoverable record of your DNS state.

What it does

• Backs up all DNS record types — A, AAAA, CNAME, MX, TXT, NS, SRV, CAA
• Exports all zones in your Cloudflare account automatically
• Saves timestamped JSON files per zone for easy diffing and audit trails
• Uses Cloudflare API v4 with Bearer token auth — no password required
• Minimal dependencies — pure Bash and curl, runs anywhere
• Designed for cron scheduling — set-and-forget daily backups
