The data for specified region is deleted. See the following in

{code}
+         // delete the dest region in FS
+         deleteRegionFromFs(regionName,
+             hRegion,
+         RegionDeletionStatus.RegionDeletionState.DEST_REGION_DELETION_FROM_FS,
+         
RegionDeletionStatus.RegionDeletionState.DEST_REGION_DELETION_FROM_FS_FAILED);
{code}
