I have a windows EC2 server that I need to implement file level backup. I have the product Backup Assist. In my previous server, I used to backup to a NAS RAID system. Now, we are using Amazon EC2 instance and I am wondering where I can backup to? I feel if I attach an S3 (?) storage drive that I could backup to this drive. If the server fails, wouldn't I be able to detach the S3 drive and attach it to another server to recover files? Any suggestions appreciated, but please be very clear, I am not an expert with servers or Amazon.
