Akonadi Server Self-Test Report
===============================

Test 1:  SUCCESS
--------

Database driver found.
Details: The QtSQL driver 'QMYSQL' is required by your current Akonadi server configuration and was found on your system.

File content of '/home/braxus/.config/akonadi/akonadiserverrc':
[Debug]
Tracer=null

[%General]
Driver=QMYSQL

[QMYSQL]
Host=
Name=akonadi
Options="UNIX_SOCKET=/tmp/akonadi-braxus.a0fF6x/mysql.socket"
ServerPath=/usr/sbin/mysqld-akonadi
StartServer=true


Test 2:  SUCCESS
--------

Akonadi is not running as root
Details: Akonadi is not running as a root/administrator user, which is the recommended setup for a secure system.

Test 3:  SUCCESS
--------

MySQL server found.
Details: You have currently configured Akonadi to use the MySQL server '/usr/sbin/mysqld-akonadi'.
Make sure you have the MySQL server installed, set the correct path and ensure you have the necessary read and execution rights on the server executable. The server executable is typically called 'mysqld'; its location varies depending on the distribution.

Test 4:  SUCCESS
--------

MySQL server is executable.
Details: MySQL server found: /usr/sbin/mysqld  Ver 5.6.28-0ubuntu0.15.10.1 for debian-linux-gnu on x86_64 ((Ubuntu))


Test 5:  ERROR

Where does Akonadi store my data?

Akonadi merely acts as a cache for your data, the actual content stays where it has always been, .ics/.vcf/MBOX files, local maildirs, IMAP- and groupware servers. There is only a limited amount of data stored exclusively in Akonadi:


Data not supported by the corresponding backends, such as email flags in case of maildir/mbox. This is comparable to KMail's binary index files stored alongside these files in pre-Akonadi times.
Internal meta-data used by application or resources, such as information about the last synchronization with a backend or translated folder names.
Data that has been changed while the corresponding backend has been offline and has not yet been uploaded.
