Automatically Split Data Files

db.robot.c > File > Split Data Files 

Split Data Files allows users to automatically split data files into year or month files, preventing them from increasing in size indefinitely.

Backup files are stored under /vdv_data_backup/ in the same folder as the original data file. For example for the file environmental.dat a backup file for the year 2015 would be stored under /vdv_data_backup/environmental_2015.dat. For most files it is sufficient to split them into year files. 

Here are 4 Sites configured to be split every year on January 1st.
