Is it possible to determine a tags archive range coverage through SDK

We are working on an update to our current system that will allow for backfilling data for the first time.  As we are still running PI Server 2010 we have the requirement of needing to reprocess archives in order to backfill data for time ranges that do not fall into the primary archive.  In some cases it may not be possible to guarantee that this reprocessing has been done already (very time consuming and limited access/time to ensure this occurs before actual deployment). We were wondering if there is some way to tell how far back a point can be accessed/read/written.


Currently of course, without the reprocessing, just blindly attempting to write the data in these un-reprocessed instances will succeed from a code standpoint but none of the data will actually make it into the prior archives.


Is there some way to detect that this is occurring?


Hopefully I have posted this in the correct area.


Any information you could provide would be greatly appreciated.


Thanks in advance.
