T 4.20 Data loss due to exhausting storage medium

Every storage medium has a limited capacity for holding data. When this limit has been reached, the result may be the loss of data and services becoming no longer available, such as:

• Users unable to save any more data;

• Incoming email is rejected;

• It is no longer possible to keep audits or audit data that have not yet been evaluated and are then overwritten.

The capacity of the storage medium can suddenly be exhausted due to various reasons, e.g. due to errors in the application program, increased storage requirements of the users or a malicious attack intended to specifically reduce the existing storage space, thus preventing audit trails from being kept.
