In case the UrBackup server crashes on Linux a gdb stacktrace is a very helpful tool in finding the cause of the crash.
- You'll need a self-compiled version of the UrBackup server, as the precompiled versions do not include debugging information. See e.g. here for how it is done in Ubuntu (Note, that you can install the package libcurl4-gnutls-dev instead of compiling it on newer systems).
- You need to have the gdb debugger installed
- With UrBackup server > 2.0:
- Run the UrBackup server via
gdb --args urbackupsrv run -v debug
If you want to log off while it runs, run it in screen
- Run the UrBackup server via
- With UrBackup Server >= 1.3:
- Run the UrBackup server via
start_urbackup_server --loglevel debug --run_in_gdb
If you want to log off while it runs, run it in screen
- Run the UrBackup server via
- If log rotation is enabled enter "handle SIGHUP nostop" in the gdb command prompt to prevent gdb from stopping during log rotation
- Enter run in the gdb command prompt to start the server
- Once it crashed enter bt to get information on the location where it crashed.
