Take Snapshot of EBS Volumes Every Three Days

Updated 1 week ago by Totalcloud

Taking snapshots of AWS EBS Volumes helps as a baseline for new volumes as well as for data backup.

There's a template already available in the web app for this use case. This workflow template helps you automate creating a snapshot of an EBS volume mentioned in the filter node if the previous snapshot taken is more than 3 days old.

Please find below the information on how this template works and how you can customize it according to your needs.

How Does This Template Work?

  1. Trigger node initiates the workflow every day at 9am.
  2. Resource node fetches all EC2 Volumes belonging to an AWS account and AWS region.
  3. Resource Node's Add-on feature fetches only snapshots of the selected EC2 Volumes.
  4. Filter node looks-up for the day the snapshot needs to be taken.
  5. User Approval node sends an email to the recipient requesting to Approve or Reject the action that follows.
  6. Action node, upon detecting Approve command, creates snapshots of the filtered EC2 Volumes.
  7. Notification node sends an email to the concerned team(s) or stakeholder(s) about the action.
