This is a subject that I feel honour bound to bring up. I have used NT for about 14 years - in that time i have had several occasions where a crash was so bad i had to use a backup. Or i wanted to keep a copy on another laptop so i just use backup. It works 1 time in 10. And it gives nonsense responses like, to continue the backup would corrupt your installation. It doesn’t help me resolve the issue.
I would love some feedback from NinjaTrader on this.
And for the record the NT versions are the same - and as I say randomly it will work, but mostly it does not. I have a workaround but by now I would have thought it was a solvable issue for NT8.
Just make a copy of the folder Documents\NinjaTrader 8 and replace the entire NT8 folder with your working backup if you run into any problems.
I use robocopy every day to back up my entire User folder which includes the NT8 folder.
Do something like this with these switches:
robocopy “C:\Users\YOUR_USER_NAME\Documents\NinjaTrader 8” “D:\NinjaTrader 8” /MIR /XJD /XD /R:1 /W:1 /MT:128 /NP /tee /NFL /NDL /NS /NC /NP /LOG:“C:\Robocopy Command Files\LogFile.log”

For backups I use KopiaUI, backup restore utility with simple UI.
yes i have been doing that for years but it seems pointless to provide a backup - which by definition is usually used in a critical situations - that is not fit for purpose. Its so unreliable if they removed it i would not notice.
not many people know this, but the file format of the backup files that ninjatrader makes are actually just zip files. What you can do is change the file extension to .zip, and then you can open the backup file just like a normal zip file, and it’s a zip file of your NT folder with whatever options you had selected for backing up. So from there you can copy over whatever you actually need, instead of re-importing the whole backup file and potentially corrupting
