I'm an Amazon Web Services specialist. (AWS = Amazon's cloud computing platform.)
I understand the workflow for taking backups in AWS. What's the equivalent in OpenStack, and is it as robust? Here is what I want to do:
Amazon EC2 Snapshot Process:
- On the server, freeze the file system or database.
- Take a snapshot onto S3 while server is live. (Possible in OpenStack? How?)
Amazon Restore Process:
- If system fails: Restore the snapshot. Amazon streams bytes of the S3 snapshot on-demand into EBS, so the system is sluggish, but service is back up in minutes. (Instant restore possible in OpenStack? How?)
