How to export a hosted zone in AWS Route 53?

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.

#!/bin/bash -e

mkdir -p $b_route53_tmp
echo "$(date) Backup all Route53 zones and resource records."
p_aws="$(which aws) --region $region"
r53_zones=$($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"'
