Trigger workflow every 48 hours

This node triggers the workflow to run every 48 hours. You can adjust the frequency if needed to suit your snapshot management requirements.

Get all droplets from DigitalOcean

Fetches a list of all the droplets in your DigitalOcean account. This is the first step in managing snapshots for each droplet.

Retrieve snapshots for a droplet

Retrieves all the snapshots associated with a specific droplet. This ensures that we know how many snapshots currently exist for each droplet.

Check if there are more than 4 snapshots

Checks if the number of snapshots for a droplet is equal to or greater than 4. If true, it proceeds to delete the oldest snapshot.

Delete the oldest snapshot

Deletes the oldest snapshot from the droplet if the number of snapshots exceeds the limit (4 in this case), based on the filter's condition.

Create a new snapshot

Creates a new snapshot for the droplet after cleaning up the old snapshots. Ensures that backups are always up to date.

What this workflow does

1. Runs every 48 hours: The workflow is triggered by a cron node that runs every 48 hours, ensuring timely snapshot management.
2. List all droplets: The workflow retrieves all droplets in the DigitalOcean account.
3. Retrieve snapshots: For each droplet, the workflow retrieves a list of existing snapshots.
4. Filter snapshots: If the number of snapshots exceeds 4, the workflow filters for snapshots that need to be deleted.
5. Delete snapshots: Excess snapshots are automatically deleted based on the filter criteria.
6. Create new snapshot: After cleaning up, the workflow creates a new snapshot for each droplet, ensuring that backups are always up-to-date.

Setup

1. DigitalOcean API Key: You’ll need to configure the HTTP Request nodes with your DigitalOcean API key. This key is required for authenticating requests to list droplets, retrieve snapshots, delete snapshots, and create new ones.
2. Snapshot Threshold: By default, the workflow is set to keep no more than 4 snapshots per droplet. This can be adjusted by modifying the filter node conditions.
3. Set Execution Frequency: The cron node is set to run every 48 hours, but you can adjust the timing to suit your needs.

Automate Droplet Snapshot Management on DigitalOcean

Built for the Let's Automate It Community by Optimus Agency

This workflow automates the management of DigitalOcean Droplet snapshots by keeping the number of snapshots under a defined limit, deleting the oldest ones, and ensuring new snapshots are created at regular intervals.

How to customize this workflow

• Adjust Snapshot Limit: Change the value in the filter node if you want to keep more or fewer snapshots.
• Modify Run Frequency: The workflow runs every 48 hours by default. You can change the frequency in the cron node to run more or less often.
• Enhance with Notifications: You can add a notification node (e.g., Slack or email) to alert you when snapshots are deleted or created.
