Akonadi y AddressBook

Algunas definiciones

Por datos reales entendemos los datos, como los contactos o eventos. Estos datos son almacenados o en un servidor groupware o en archivos locales. Exactamente depende del recurso que estés utilizando. Por ejemplo, el recurso Contactos Personales almacena sus datos en $HOME/.local/share/contacts mientras que el recurso VCard File (cuyo uso no se recomienda ) almacena sus datos en $HOME/.kde/share/apps/kabc/std.vcf.

Los datos almacenados en cache son copias de los datos reales que están almacenados en la base de datos para un acceso más rápido y una utilización sin conexión. La base de datos también contiene los meta datos que son datos para la gestión necesarios para que Akonadi funcione correctamente.

Los datos de configuración son los datos que configuran el servidor Akonadi y los recursos individuales. Los datos de configuración para el servidor se encuentran en $HOME/.config/akonadi, y las configuraciones de los recursos se encuentran en su mayoría en $HOME/.kde/share/config/akonadi_xyz_resourcerc# (xyz es el nombre del recurso y # su número de instancia).

Organising Backups

So now we need to decide what to back up. If you want to backup the "real data", then it depends on the resources you have configured... if you use a groupware server, then the backup should be done there. For contacts, the files under $HOME/.local/share/contacts will normally be what you need.

The Akonadi tray icon offers you a backup and restore function. That backs up the "cache data" which might not include all of your data! It can be helpful if you want to clone a system 1:1, then you can copy the cached data together with the real data and the configuration, so you don't have to load the data again from the sources (e.g. groupware server).

Examining your Resources

KRunner offers you Akonadi Resource Configuration, or you can access this through the Akonadi tray icon -> Configure. You may find several resources set up. You may find one labelled

Address Book - No KDE address book plugin configured yet.

That's the old compatibility bridge (possibly created by the migrator tool). You should remove this one!

std.vcf - Ready

This is the VCard File Resource which points to $HOME/.kde/share/apps/kabc/std.vcf per default. It is not recommended that you use that one, as it doesn't share the benefit of Akonadi.

Personal Contacts - Offline

That's the preferred resource for your local contacts which points to

 $HOME/.local/share/contacts

Note that this may say "Offline" when in fact you are using it. This is a display bug, and can safely be ignored.

And when more components use Akonadi?

When the rest of the components move to Akonadi, will all the data be under ~/.local/share? That should make backup easy. Well, contacts and mails are stored there now, I don't know what the plan for events/todos is, but it would make sense to store them there as well. We'll keep it in mind when discussion pops up!
