Cumulative trade data database

[guillembm]

Several weeks ago I discovered that an excess of trade data on my settings folder provoked a lack of NT performance.

The solution is simple. Just resetting the database is enough to see a significant improve. Before doing this I make a backup of the existing trade data.

I would like to restore these backups to reconstruct the whole data base but each time I restore a backup it deletes the data of the previous.

Is there a way to reconstruct a whole database keeping all the previous backups?

guillembm, that would unfortunately not be possible - if you restore the DB it would be taking the complete old file and replace this in the process it would not amend. You could for example export trade performance data to Excel weekly and then reset after it's done, this would minimize the working DB size then.
