Export not working, help needed

[soulflyman]

Hi, I have to export the data of an sysPass installation. I can log in as admin and CRUD entries but I can't export them.
I need them in clear text and I think syspass-decrypter might help.
But the xml export is not working. I always get an empty tar.gz file with 0kb.
Any tips on how I can get an export of the data?

#1670 describes the same problem, I found the generated export file in the filesystem on the webserver.
The files can be found in ./sysPass/app/backup and from there they can be downloaded manually.
