• Keeps up to N snapshots
• Copies tags from volumes to snapshots
• Safeguards against "pending" snapshots
• Available both as a command-line program and Lambda function

Back up attached volumes tagged with Name=db-* and attached to /dev/xvdf, retaining up to 3 snapshots per volume.

$ ebs-backup --name 'db-*' --device /dev/xvdf --limit 3

The program will back up all volumes that match the following criteria:

• tagged with Name = "db-*"
• attachment state is "attached"
• attachment device is "/dev/xvdf"
• have no "pending" snapshots being created

A full end-to-end test suite is located in test/aws subdirectory. See the test_aws target in the Makefile.

The Lambda function is automatically uploaded by CircleCI to S3 at each build. The filename pattern is as follows: s3://${BUCKET_NAME}/ebs-backup/ebs-backup-lambda-${VERSION}.zip

A useful Terraform module for deploying ebs-backup on AWS is located in the terraform/scheduled_backup subdirectory. See the input.tf file for supported variables.

S3 bucket and key locations for the most recent release can be found in Parameter Store in the segment-ops AWS account. These can be useful for provisioning. See the update_parameter_store target in the Makefile.

• S3 bucket: segment/ebs_backup/lambda_s3_bucket
• S3 key: segment/ebs_backup/lambda_s3_key
