If I had to guess, I would guess that, at some point, someone removed
Data.fs and restored it from backup without restarting the process.
If that happened, the process would still be writing to the removed
database.  That's just a wild guess.  I wonder if the Data.fs file matches
a backup made on the 14th.

Unlikely.
