[cs615asa] Some questions.

[hyan2]

Hi Professor,

The questions are following:

1. For this example "To back up the entire filesystem to a volume 
tagged as `backup' (which, it should be noted, must hence also contain a 
filesystem) using rsync(1): ec2-backup -t backup -m rsync -d /". Is that 
means when user want to back up entire filesystem, the back up method 
must be entered and must be rsync?

2. If the tag of volume is exist but full, what should the program do 
next? Create a new volume with the new tag name automatically or delete 
the content of that volume and back up to that volume.

3. When creating a new instance, what public key should the program 
use? Do I need to read from system environment to find the public key? 
Since I find that the user can change their private key to ssh to the 
server in your example.

Thank you for your help.

Best,

-Han
