I'm looking for an answer regarding the best method to backup large spanned or striped volumes for windows EBS backed instances. Best as defined by fast, low cost, and using the existing AWS environment without any ad-ons if possible.
Scenario: Windows Server with several 1TB EBS Volumes attached needs a backup plan.
Tried: Using CloudBerry Backup to backup to S3.
Verdict: Possible but quite slow and first backup will take large amount of time.
Tried: AWS support to devise a snapshot based plan. Verdict: Support indicated that they could not get the instance to recognize the volumes as spanned in the case of a restore. Though perhaps windows experts will know more about if this is possible.
Other ideas: AMI? Backup Server in other Availability Region?
