I see no option to export a backup of the settings for a domain.

Maybe I should save the results of public DNS with dig but I would question whether a friend knows a better way.

Yes, it can be more friendly way. I suggest using cli53 tool, https://github.com/barnybug/cli53

After you setup it, just try

cli53 export --full sciworth.com

And you get the export zone in bind format.

No need of additional software installations. You need only awscli.

Here is what I just wrote. It is simple and works like charm.

#  gzip
#  awk

r53_zones=$($p_aws route53 list-hosted-zones --query '[HostedZones[*].[Id, Name]]' --output text | awk -F'/' '{print $3}')
if [ ! -z "$r53_zones" ]; then
        while read route; do
                zone=$(echo "$route" | awk '{print $1}')
                domain=$(echo "$route" | awk '{print $2}')
                echo "Processing $zone / $domain"
                $p_aws route53 list-resource-record-sets --hosted-zone-id "$zone" --output json > "$b_route53_tmp"/$(date +%Y%m%d%H%M%S)-"$zone"-"$domain"backup.json
        done <<<"$r53_zones"

        echo "Archive json files."
        gzip "$b_route53_tmp"/*backup.json
        echo "Backup $zone / $domain data to $b_route53_bucket/$(date +%Y)/$(date +%m)/$(date +%d)/"
        $p_aws s3 cp "$b_route53_tmp"/ $b_route53_bucket/$(date +%Y)/$(date +%m)/$(date +%d)/ --exclude "*" --include "*.gz" --recursive
fi

echo "$(date) Done!"

If you want to export to bind format, you can use this script:

#!/bin/bash

zonename=$1
hostedzoneid=$(aws route53 list-hosted-zones | jq -r ".HostedZones[] | select(.Name == \"$zonename.\") | .Id" | cut -d'/' -f3)
aws route53 list-resource-record-sets --hosted-zone-id $hostedzoneid --output json | jq -jr '.ResourceRecordSets[] | "\(.Name) \t\(.TTL) \t\(.Type) \t\(.ResourceRecords[].Value)\n"'

To export a hosted zone in AWS Route 53, follow these steps (let say you are using example.com hosted zone):

Step 1: Installation – pip install route53-transfer

Step 2: Backup the zone to a CSV file:

route53-transfer dump example.com backup.csv

Use STDOUT instead of a file

route53-transfer dump example.com –

Step 3: Restore a zone:

route53-transfer load example.com backup.csv

Use - to load from STDIN instead

Migrate between accounts:

Use command line switches for overriding the access and secret keys:

route53-transfer --access-key-id=ACCOUNT1 --secret-key=SECRET dump example.com
route53-transfer --access-key-id=ACCOUNT2 --secret-key=SECRET load example.com

If you are working with private zones, use –private to distinguish private domains:

route53-transfer --private dump example.com example-private.csv
route53-transfer dump example.com example-public.csv

I wrote quick simple backup script

#!/usr/bin/env bash

#set your vars
date=$(date +%j%m%Y)
backup_to="/change/this/to/your/destination/backup/dir"
backup_command_path="/usr/local/bin/cli53"
backup_command="cli53 export"

#check if cli53 exist
if ! [ -f $backup_command_path ]; then
    echo -e " file do not exist\n please install it from https://github.com/barnybug/cli53/releases/latest"
    exit 1
fi

#get list of domains to backup
domains=$(cli53 l | awk '{print $2}'| sed 's/.$//' | sed 's/Nam//')

cd $backup_to

for i in ${domains[@]}; do
    cli53 export $i > $i
done

#list backup directory
echo -e " the following zones where backup:\n"
ls -l
-2

You can sign up for Cloudflare.com and add a free website.

Cloudflare will scan your DNS as part of its onboarding.

After import (or maybe during), in "Advanced" below the DNS records, there is an Export DNS file button.

  • True, it will scan, but it just makes guesses about what you might have, and it uses IPs instead of most CNAMES. – MichaelCodes Oct 6 '20 at 20:19
