Hello,
I have been playing with EFS backup and restore and using python boto3 client for all the operations. I came across an edge-case scenario where EFS restore does not work. Below are the steps (all operations were done using python boto3 client unless explicitly mentioned)
- I created an EFS backup. I then used the recovery point ARN to restore it back to the same file system by calling start_restore_job(). This created a restore job which successfully completed and created a separate restore directory on the file system
- I then deleted the restored directory from the file system.
- I then called start_restore_job() again using the same recovery point ARN and to the same file system. I expected it to create a new restore job, however it failed with error "An error occurred (InvalidParameterValueException) when calling StartRestoreJob operation: Restore job xyz already finished". xyz is the same restore job that was created in the first step. Looks like it does not create a new restore job if one has already completed successfully.
- I then ran the restore operation from the console and it did create a new restore job as expected.
I am not sure whether this is a bug with boto3 client or the API itself, but I should be allowed to run multiple restores for the same recovery point ARN.

Did you provide the IdempotencyToken? If you want to initiate a new Restore Job, you need to provide a new IdempotencyToken when making the API call.
