rsync - Nov 2024 - Errors with program diagnostics (code 13) after rsync upgrade

Dear All,

Having weird rsync issues after upgrading FreeBSD from 13.2 to 14.1 and 
rsync along with it. I cannot find any solution. Setup: doing rsync 
backup from the root ZFS to an SSD mounted to /media/da0p1. The rsync is 
initiated as root using /etc/crontab. The log:

2024/11/15 08:30:01 [61842] building file list
<... a few hundred files listed here - no error messages! ..>
2024/11/15 08:30:41 [61842] sent 15069073 bytes? received 77859 bytes? 
total size 104786993196
2024/11/15 08:30:41 [61842] rsync error: errors with program diagnostics 
(code 13) at log.c(245) [sender=3.3.0]

I assume code 13 is related to permissions, but given rsync is started 
as root, why would this happen? The same rsync commands worked on all 
previous versions of FreeBSD. It also fails with the same error to a 
remote SSH host. If I run my rsync backup scripts manually as root then 
everything works fine, so the issue appears only when the script is 
initiated by cron.

/etc/crontab entry:
30??? *??? *??? *??? *?????? root 
/home/blackhaz/scripts/rsync-to-external-drive

rsync command in the script:

if mount | grep $TARGET_DISK; then
 ?????? nice rsync --log-file=$RSYNC_LOG_FILE \
 ?????? --archive --hard-links --delete --delete-excluded --sparse 
--xattrs --numeric-ids --acls --progress \
 ?????? / /media/$TARGET_DISK/freebsd-backup

Would appreciate any pointers. Tried without--hard-links and getting the 
same error.

Regards,
Maxim Usatov

This is just a very wild and uneducated guess, but I would try it
without the nice.

Also: without the xattrs and acls. So 3 things to try :-P
