Thanks Bill, you nailed it.
04-Jan-2022 16:13:52 FD: backup.c:1356-884680
fname=/Users/USER/Library/Containers/com.apple.Safari.CacheDeleteExtension
snap=/Users/USER/Library/Containers/com.apple.Safari.CacheDeleteExtension link=/Users/USER/Library/Containers/com.apple.Safari.CacheDeleteExtension/
Last file before error is thrown and job craps out.
I would if that's the only file, will try to exclude and see how far the
job can go.
Also, note a debug level of 150 is way more than needed to troubleshoot
this and I canceled attempt after trace file was 60G. level=10 was
enough to log which files were being backedup as well as the error that
terminated job.

Yes, backing up a single file on my problem hosts does succeed.

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
