EC2 automate backup requires volumeid parameter and already provided

Question

I downloaded this EC2 automate backup tool and upload it on ec2-user folder. I used SSH to execute it

/home/ec2-user/ec2-automate-backup/ec2-automate-backup.sh -v "vol-XXXXXXXX"

and returned:

The selection method "volumeid" (which is ec2-automate-backup.sh's default 
selection_method of operation or requested by using the -s volumeid parameter) 
requires a volumeid (-v volumeid) for operation. Correct usage is as follows: 
"-v vol-6d6a0527","-s volumeid -v vol-6d6a0527" or "-v "vol-6d6a0527 
vol-636a0112"" if multiple volumes are to be selected.

Answer 1

Remove the double quote, you only need them if multiple volumes are to be selected.
