Abstract
The present invention relates to a data block based backup method for a data management system. The data management system comprises a file system that controls access by a database application to at least one database container file stored the data management system. The data management system further comprises a backup client that is connected to a remote backup server, whereby a first version of the database container file is saved in the backup server and a first inode containing information on data blocks of the first version of the database container file. The method may include creating a change tracking table for at least the database container file and adding an entry in the change tracking table, whereby the entry has an indication of the respective data block in association with an information indicating the type of the access.
