During mounting operations, users can select a local or remote copy (if configured) for mounting, and if they want to recover the application (optional). The details are defined by the user within the AppSync service plans or repurposing workflows. AppSync attaches the copy to the selected mount host by creating a thin clone from the snapshot and mounting it. If the copy is unmounted, the thin clone is unmapped from the mount host but remains on the PowerStore appliance. This allows AppSync to quickly remount this copy if it is needed again, ensuring optimal performance. The copy is only deleted from the PowerStore appliance if it is expired in AppSync. This results in the thin clone and snapshot both being deleted. If the copy is using a thin clone, no additional thin clone is created during a mount operation. This is because thin clones can be mounted and snapshots cannot.
