Quickly backup and restore AWS Route53 DNS zones.
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.
pip install route53-transfer-ng
List all the hosted zones in the current AWS account (use the AWS_PROFILE
environment variable to control which account is active):
route53-transfer-ng zones
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.
