A Terraform module to automate the taking of backup snapshots.
Include this repository as a module in your existing terraform code:
module "ebsnapshot" {
source = "JamesWoolfenden/ebssnap/aws"
version = "0.2.9"
common_tags = var.common_tags
snapshot_name = local.snapshot_name
cron_expression = var.cron_expression
regions = var.regions
}Creates a lambda and cloudwatch event to look for any instances that have the specified tag and then takes a snapshot of that volume. This is a heavily modified version of this module: https://github.com/kgorskowski/ebs_bckup
Set up your Terraform tf.vars file to look something like:
common_tags = {
application = "terraform"
module = "auto-ebs-snapshot"
environment = "develop"
}
EC2_INSTANCE_TAG = "Backup"
RETENTION_DAYS = 10
cron_expression = "45 1 * * ? *"
regions = ["eu-west-1","eu-west-2","eu-west-3"]No requirements.
