Akonadi and AddressBook/sv

Den här informationen kommer från Tobias Koenig, utvecklare av KDE-PIM.

Några definitioner

Med 'riktig data' menar vi data som t.ex. kontakter och planerade möten. Sådan data lagras antingen på en groupware server eller i lokala filer. Exakt var beror på vilken resurs som används. Resursen 'Personliga Kontakter' lagrar t.ex. sin data i $HOME/.local/share/contacts medan resursen 'VCard Fil' (som för övrigt inte borde användas ) lagrar sin data i $HOME/.kde/share/apps/kabc/std.vcf.

Den 'cachade datan' är kopior av den 'riktiga datan' som lagras i databasen för snabbare åtkomst och offline caching. Databasen lagrar även 'meta data' som krävs för att Akonadi ska kunna hantera databasen.

The 'configuration data' are the data that configure the Akonadi server and the individual resources. The configuration data for the server can be found under $HOME/.config/akonadi, the configuration for the resources are mostly stored under $HOME/.kde/share/config/akonadi_xyz_resourcerc# (xyz is name of resource and # its instance number).

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 helpfull 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!
