Determination of relevant figures for database recovery processes

Abstract

The invention relates to a method of determining relevant figures that describe time within a database recovery process, wherein the database comprises at least a multitude of objects and a multitude of log files, wherein the objects are stored in object backups, wherein the database is stored in system backups, in which changes in objects are recorded in log files, and wherein for the purpose of recovering the database in a state at a determinable target point in time objects are reconstructed at least in part from the log files based on the object backups or the system backups. A prediction of the duration of a recovery process can be made in that for a recovery of the database from the system backup the size of the system backup to be retrieved is determined, that for a recovery of the database from the object backups the size of the object backups to be retrieved is determined and that prior to a database recovery the relevant figures are calculated based on the determined sizes and displayed.
