Hello Jürgen, thanks for explaining. It cause a little problem in "test_backintime.py::TestBackInTime.test_local_snapshot_is_successful()" (https://github.com/bit-team/backintime/blob/4b09eba80237d64b84a3ed2c4aba1c44...) The output on stderr is explicit checked here if it fits to that lines INFO: Lock INFO: Take a new snapshot. Profile: 1 Main profile INFO: Call rsync to take the snapshot INFO: Save config file INFO: Save permissions INFO: Create info file INFO: Unlock But in my situation (testing machine without installed BIT but running BIT from git repo) it fails because there are also that WARNING messages in. It seems to me it is the only test that is affected. What do you think how to handle that? One approach would be to modify the test that way that it still checks for the existence of that INFO lines but ignore the other lines. What do you think? Kind Christian
