[cs615asa] EC2_BACKUP_FLAGS_AWS question

[wzhang32]

   As it's said before, we can create a suitable instance for backup ec2 
volume. However, the "--key-name" and "--security-group" is a mandatory 
parameter which is completely different in different computers. I try to 
force a user to export EC2_BACKUP_FLAGS_AWS obligatory which value could 
be "--key-name USER-KEY-PAIR --security-group USER-SECURITY-GROUP 
--instance-type t1.micro". If "--key-name" and "--security-group" are 
found not set, an error message echos. But I don't think it's a better 
way to deal with "--key-name" and "--security-group", could you give me 
some hint to solve this problem?
