[cs615asa] HW6

[Yifang Yuan]

Hi Professor:
I have two questions about hw6

Q1
In order to backup, we need to create a temporary aws instance. Must it also be ami-569ed93c(NetBsd)?
I tried dd of=/dev/xbd2a/ after mount. The system always report device busy. But it can work on other OS, such as  Amazon Linux.

The program requires “write out the data to the raw volume”. Does below meet it:
tar cf - <dir> | ssh ec2-instance "dd of=/backup/backup.tar”  (/dev/sda is mount to /backup)

Q2
Do we still write what we learn in README?
