Corrupted Market Replay data

[maxpi]

I was testing an indicator I was writing on replay data. I made code mistakes where I was referencing the bar before the first bar, perhaps had a divide by zero or two, stopped and started the replay, moved it forward and backwards in time without regard to whether it was stopped or not, etc.... eventually the data bacame corrupted somehow... NT version 6.0.1000.5

Where is that data stored exactly and can it be backed up?

Data is stored in My Documents\NinjaTrader 6\db\data

In 6.5, there is a back up service that will take care of this for you.
