Once you have Deployed and Linked your Altaro Endpoint Agents to your Endpoint Manager, the next step is to Approve them for backups.
To do so, simply go to [Setup] > [Unapproved Endpoints]
Here you will get a list of Endpoints awaiting approval for backup, select the ones you'd like to approve and then click on [Approve Endpoints]
If you didn't specify a Backup Policy (if you deployed automatically via a script), you will be prompted with the following screen to pick one for each Endpoint.
Then click [Next] and lastly [Approve] to successfully confirm Endpoint Approval.
