Recent developments in the area of hard drives make it possible to store a huge variety of distinct types of documents about a person’s life . These documents can be audio, video, images and different text types which were created using desktop computers, tablet PCs, Smartphones, digital cameras and plenty of other electronic devices. These personal archives are usually referred to as Human Digital Memories (HDMs) and make it possible for the user to store all his available media about every event in his past and remember it again . The size of these archives increases literally every day. This is why it is almost impossible to benefit from this information without being able to retrieve the necessary data efficiently . However the standard methods of Information Retrieval cannot be applied to these archives blindly because the data inside of them is usually very noisy as it might for instance contain several similar pictures or irrelevant SPAM emails. Moreover the user has unique associations about the contained files which are not easy to anticipate. This is why there is a special discipline called Personal Information Management (PIM) which deals with these special archives .
From a theoretical point of view, these archives can be either stored in the internal memory of the user’s device like it is done in  or in the cloud. Both systems have several disadvantages which might reduce their attractiveness for the user. The former concept is problematic as two of three sold computers in 2011 were laptops . It is assumed that about one of three laptops breaks within 3 years  which can destroy the HDM. Regarding the previously mentioned number of devices manual synchronisation with the computer is required. It appears to be unlikely that a significant number of people does that so these photos, messages and videos cannot be retrieved using the computer. Using a cloud service on the other hand means that the user loses control over his private data  and becomes dependent on the service provider: If this provider increases the price for his service the customer will have to accept it because moving several gigabytes of data to another provider is very laborious.
2. Overview of the objectives
In order to avoid these significant disadvantages the author proposes to use a home server (HS) instead. This HS is a computer which has enough storage space and is running a special operation system which is able to perform all the necessary PIM tasks. As depicted in Illustration 1: the server is connected to a router and stores all the documents from the devices within the network of the household and from web services like Facebook and Dropbox. Each user has his own account and can retrieve only his own documents over a web interface both inside this network and over the Internet. Moreover certain content might be available for several users if it belongs to all of them.
