Method for determining the contents of a restoration log

A method for creating restoration log records in a restoration log in a data system, that comprises software and hardware resources and a database containing software representations of the resources, said resource representations containing data in associated attributes, and being exposable to operations via a managing function from a process associated with the data system or from an operations system for the data system, wherein a restoration log record shall reflect an updating of a resource representation that is performed from the process or from the operations system,

• comprising the step of:
• to enable conditional creation of a log record in the restoration log in case of an operation directed via the managing function towards a resource representation, providing each resource representation with logging information informing whether an updating of the resource representation shall be logged in the restoration log, said logging information including a log indication in each attribute for indicating logging in case an operation shall be logged and for indicating non-logging in case an operation shall not be logged, wherein the managing function at appearance of an operation
• checks whether there is the question of a data changing operation and if this is the case
• prepares log data corresponding to the operation,
• executes the operation,
• checks the log indication of each attribute of resource representations affected by the operation, and if the log indication indicates that logging shall be performed the prepared log data of said each attribute is sent to the restoration log, otherwise the prepared log data of the attribute is discarded.
