route53-transfer-ng

Quickly backup and restore AWS Route53 DNS zones.

Motivation

route53-transfer-ng started as a pull-request to route53-transfer and slowly turned into a port to boto3 of that software, and then finally a complete rewrite.

I intentionally avoided retaining compatibility with the original code. In fact, route53-transfer-ng does not use the CSV format anymore, as that wouldn't easily allow support for all the Route53 routing policies and features.

Installation

pip install route53-transfer-ng

Usage

Backup the example.com zone to a YAML file:

route53-transfer-ng dump --format yaml example.com example.com.yaml

Use STDOUT instead of a file:

route53-transfer-ng dump --format yaml example.com -

Restore the example.com zone from a YAML file:

route53-transfer-ng load --format yaml example.com example.com.yaml

To perform a dry run load, add the --dry-run option switch. The command will show the changes that would be made to the R53 zone without carrying out any operation.

route53-transfer-ng --dry-run load example.com example.com.yaml

It's possible to use upsert operations when performing a route53 change operation, instead of the default DELETE + CREATE of recordsets. To enable this behaviour, supply the --use-upserts option.

route53-transfer-ng --dry-run --use-upserts load example.com example.com.yaml

Use - as filename to load from STDIN instead.

Migrate between accounts:

Use the AWS_PROFILE environment variable to change the AWS account to be used by route53-transfer-ng. Dump from one account, load into another.

AWS_PROFILE=aws_account1 route53-transfer dump example.com test.yaml
AWS_PROFILE=aws_account2 route53-transfer load example.com test.yaml

Thanks to Cosmin Sterejan for the original route53-transfer that I used for some time as-is and then as base and inspiration for this boto3 "ng" version.
