Hello list,

I have two Raspberry PI's running Raspbian:


One of the Raspi's (heRPI01) is being backed up without any problems. The other one \
(heRPI02), however, refused to make backups after a first and successful backup:


$ uname -a
Linux heRPI02 4.9.80-v7+ #1098 SMP Fri Mar 9 19:11:42 GMT 2018 armv7l GNU/Linux

$ cat /etc/debian_version
9.4


 From the job log:

I started the FD and the SD with "-d 999" and uploaded the debug output to pastebin:

As an end-user (in contrast to a developer ;-) ) I see that the fd segfault's: (<-- \

Any ideas what could be wrong? Anything obvious I'm missing?



Thanks a lot and have a nice (easter) weekend!


Cheers,

Thorsten
