- ScriptExecutionState
- CopyMsWindowsSnapshotState
- CopyMsWindowsSnapshot::SourceInstanceLaunchedState
- Defined in:
- lib/scripts/ec2/copy_mswindows_snapshot.rb
Overview
Source instance is started. Steps:
- create and attach a volume from the Snapshot of the AMI to copy
- create and attach a temp volume of the same size to dump and compress the entire drive
- create a filesystem on the temp volume and mount the temp volume
- dump and compress the entire drive to the temp volume
