Hello Stephen,

This issue looked familiar to me, so I checked internally and I think I found 
something.

I am pretty sure that this is an issue due to the larger possible size of 
extended attributes that Big Sur uses.

 From what I can gather, this has been addressed and fixed in Bacula 
Enterprise, and the fix will appear in the next Bacula
Community release. (no ETA that I am aware of yet, but I assume very soon)

In the case I found, running the FD in debug mode, level=150 revealed there was 
an issue with one specific file:
----8<----
/Users/<UserName>/Library/Containers/com.apple.Safari.CacheDeleteExtension
----8<----

The temporary workaround at the time (Sept 2021) was to omit this file (or 
whichever file your system is working on when the
job fails) from the backups.

No idea if this means much, but there was also a mention made: "this seems to 
be related to Time Machine"


Setting the FD in debug mode:

* setdebug level=150 options=tc trace=1 client=xxxx

Then, run the backup until it fails, and stop debugging:

* setdebug level=0 trace=0 client=xxxx

In /opt/bacula/working on the FD (or wherever "WorkingDirectory" is set to), 
there will be a *.trace file. You will be
looking for the file mentioned before the error:
----8<----
bxattr.c:310-69825 Network send error to SD. ERR=Broken pipe
----8<----


Hope this helps.
Bill
