I maintain two kmy files, one for personal finances, and another for an organization for which I am Treasurer. I want the backups of those saved in different folders, but now I must either copy some of them to a different folder, or else remember to reset the backup folder based on which file I have open. My preference would be to store this backup folder within the data file itself, since there can only be one. If it is stored in the user's configuration file, it would need to be the pair of file name and backup folder, and that list would be likely to proliferate in include long unused entries.
