Our MongoDB had been broken due to unexpected shutdown of server.

And I requested community to help repair it.

I had provided WiredTiger files, and received updated one from community.

And replaced old wiredtiger files with those one, and db was repaired.

But the disaster is that I've lost last month's data after repair.

I still have back up of broken db (before repair) including old wiredTiger files and new repaired wiredTiger files (the community provided for fix).

Is there any way to recover my lost data? I have full backup of the origin DB which is on broken status.

Thanks in advance!
