I now did recreate the entire data (from the backup) of 1,300,000,000 triples using TDB2 loader and splitting the files into smaller pieces (52 files each 4GB unzipped) and it did succeed—by the way: it failed first attempting loading the entire 8GB zipped data backup, that’s why I split it. I have a slightly different server setup, but I did it like it is described here: https://github.com/stain/jena-docker/issues/74 The database acts now as expected, and when doing MOVE GRAPH … it returns now: Update succeeded (34509.994 seconds …took a while ;-) So the solution in my case was: - backup all data - reimport all data to get a proper data structure Thank you for all your help Andreas
