Assigning Resources to Backup Plan:
Select the Backup plan which you have created, Under Resource Assignments , We are going to apply the backup plan to our AWS resources.
Click Assign resources , Give a name to an assignment , We will use the default role.
Next We have to choose the resources based on the Tags or Resource ID
Select Resource ID ,If you havn’t tagged your AWS resources.
Select the Resource type , and select the particular resource.
