All snapshots in StorPool are crash consistent. StorPool supports atomic snapshots of multiple volumes – e.g. all virtual disks of a VM can be snapshotted at a single point of time, providing consistent backup and restore for multi-disk systems.
The StorPool REST-API allows creating a snapshot of multiple volumes with a single call by specifying the names of the volumes. The snapshots created in this way store the respective volumes at exactly the same point in time thus preserving data consisteny across an application. There is no requirement to group volumes in advance.
