Lost data - Overwritten Data

[nanook77]

Last week, i uploaded some tick data and inadvertently overwrote some of my previously save tick data back in 2011.

I have about 13GB of save NT backup files for that period, covering several instruments. Is there anyway to retrieve this data from those various backup files (all these backup were set with 'save for tick replay as well).

If so what is the procedure, as this data covers several contract periods in the cl and tf futures?

thanks in advance

Hello nanook77,

Thank you for your post.

Unfortunately, there is no way to recover only the historical chart data from the backup archives. When restoring, the entrie backup archive is restored.

You can restore NinjaTrader to a previous backup, if that backup has the tick data before it was altered then it will be restored as well. For information on restoring from a backup archive please visit the following link: http://www.ninjatrader.com/support/h...up_archive.htm

For a video on backing up and restoring please visit the following link: http://youtu.be/zGCp9ebpV1M

Please let me know if I may be of further assistance.
