Algunes definicions

Per dades reals entenem les dades, com els contactes o esdeveniments. Aquestes dades són desades o en un servidor groupware o en fitxers locals. On exactament dependrà del recurs que estigueu utilitzant. Per exemple, el recurs Contactes personals desa les seves dades a $HOME/.local/share/contacts mentre que el recurs Fitxer VCard (l'ús del qual no es recomana Face-smile.png) desa les seves dades a $HOME/.kde/share/apps/kabc/std.vcf.

Les dades desades al cau són còpies de les dades reals que estan desades a la base de dades per a un accés més ràpid i una utilització sense connexió. La base de dades també conté les meta-dades, que són dades per a la gestió necessàries per a que Akonadi funcioni correctament.

Les dades de configuració són les dades que configuren el servidor Akonadi i els recursos individuals. Les dades de configuració per al servidor es troben a $HOME/.config/akonadi, i les configuracions dels recursos es troben en la seva majoria a $HOME/.kde/share/config/akonadi_xyz_resourcerc# (xyz és el nom del recurs i # el seu nombre d'instància).

The Akonadi server configuration is a couple of files in $HOME/.config/akonadi - this can be changed through environment variables, $XDG_DATA_HOME and $XDG_CONFIG_HOME, defaulting to $HOME/.local/share and $HOME/.config respectively if not set. It contains which data sources and helper programs are active and will be started and watched (so they can be restarted on crashes) by one of Akonadi's server processes (akonadi_control). KDE's local base directory can be changed using $KDEHOME environment variable, defaulting to $HOME/.kde when not set (or to $HOME/.kde4 if the distributor changed the default by patching the code).


kde4-config --path data

Each data source handler (called resources) or helper program (called agents) can have its own configuration although some agents or resources don't require configuration. The general rule is that for every entry in $HOME/.config/akonadi/agentsrc there is a corresponding configuration file in $HOME/.kde/share/config. For example, if the [Instances] section in agentrc contains an entry for akonadi_ical_resource_2, there is also a config file called akonadi_ical_resource_2rc in the KDE config directory.

Depending on the type of data, such config files for resources will have filenames or directory names of where the data is stored. Common locations are KDE's legacy default files, e.g. $HOME/.kde/share/apps/korganizer/std.ics. New default locations are files and directories in $HOME/.local/share, e.g. $HOME/.local/share/contacts.

For now (as in actually released versions) the database is merely used for caching and keeping structural information (e.g. which addressbook a contact belongs to). This will change when Akonadi is being used for email, since state information like read/unread is also stored there (unless the backend is also capable of doing this, e.g. IMAP).

Organitzar les còpies de seguretat

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).

Examinar els vostres recursos

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


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

I quan els diversos components utilitzen 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!

Solució de problemes

Problem: You update to 4.6 and your addressbook is suddenly completely blank

Solution: This is new behaviour in 4.6 - you can choose whether to display specific addressbooks or all of them. In front of each addressbook name there is a checkbox. Use that to enable the addressbooks you want to use.
