-	It is expected that you use this inside a script, to loop through
-	all possible volume ids that needs to be backup to local folder.
-	
-	The volume id does not need to exist locally or even remotely.
-	This will help to backup future new volumes.
-	
-	Usually backing up is just copying the .dat (and .idx) files.
-	But it's tricky to incremententally copy the differences.
-	
-	The complexity comes when there are multiple addition, deletion and compaction.
-	This tool will handle them correctly and efficiently, avoiding unnecessary data transporation.
