KOrganizer/Kontact file system

I have not been able to find instructions on how to save their data on a removable USB hard drive. I don’t mean a backup. The daily operations. Not the configuration files, just the data.

For the case of the e-Mail (KMail) it’s easy – there’s an automatic Archive function which can be setup, per Mail Folder, to run at intervals as required.
For the case of the Calender and Tasks it’s not as easy –

  • I setup on a “per year” basis and then via the “Files” → “Export” function drop the ICS files in a directory.
  • Ditto for the Address Book.

I suspect that, there’s no automatic Archive function for the Address Book and the Calendar/Tasks because, these functions are often managed together with Groupware – such as “Kolab”.
