Lots of DNS tools speak text/dns natively - and being able to easily get all zones in that format makes things like export / point in time backups much easier.
Now, at every deploy to production, we do a backup of the DNS configuration on Cloudflare and save it on S3. This hardly costs us anything as each backup is only a small text file. But I now feel much more comfortable when editing our DNS config.
`--export=s3`, `--export=gcs`
https://dns-api.com/ is my approach to that problem.
