We have some servers on Amazon EC2, and we back up the entire file system using cumulus. I'm wondering how to restore the entire file system from cumulus on to an EC2 instance - we need to do a test restore. Some ways I can imagine:
- Amazon has some way of filling the root filesystem before boot.
- Set up an instance and restore the files to /tmp. To copy it all to root I'd have to stop the instance running, otherwise there would be problems with open files, but I'm not sure how to access the filesystem of a stopped instance.
And, yes, I am new to EC2, so I may be missing some obvious tools.
