Group Snapshot

robustack.com

• Freezes Filesystems if configured to do that and start snapshot EBS Volumes (including root Volumes) immediately. Just after start snapshot initiated, unfreezes Filesystems.
• Saves the status of Filesystems and Instances when the Snapshot Initiated for future reference
• Restoring GroupStack Snapshot which was taken while it was running MAY NOT BE SUCCESSFUL. You should verify it.

Group Snapshot Restore

robustack.com

• Group Snapshot is restorable when the GroupStack is in 'stopped' status.
• You can increase the size of GroupStack Volumes (including root) through 'Restore GroupStack'.
• Detaches Volumes (includeing root) from Instances and creates new volumes from Group Snapshot
• Attaches Volumes to the instances if the creation completed.
• Starts Instances and resizes root Volumes
• Resizes and mounts (or vice versa) Filesystems

Clone GroupStack

robustack.com

• You can Clone GroupStack with Group Snapshot.
• Cloning GroupStack can be done over other Availability Zone or other Region or other AWS account.
