Holger asked the right questions. Yes, it's an ssh problem, as you note.
You've come across what is one of the more likely upgrade issues.
In looking at your rsync_bpc command, it doesn't look like $Conf{RsyncArgs}
was updated when you installed 4.0, or you have a per-host override.
Here's what a typical rsync_bpc command should look like:
/usr/local/bin/rsync_bpc --bpc-top-dir /data/BackupPC4 --bpc-host-name
HOSTNAME --bpc-share-name /LOCALPATH --bpc-bkup-num 0 --bpc-bkup-comp 3
--bpc-bkup-prevnum -1 --bpc-bkup-prevcomp -1 --bpc-bkup-inode0 1
--bpc-attrib-new --bpc-log-level 1 -e /usr/bin/ssh -l root
--rsync-path=/usr/local/bin/rsync --super --recursive --numeric-ids --perms
--owner --group -D --times --links --hard-links --delete --partial
--log-format=log: %o %i %B %8U,%8G %9l %f%L --stats --checksum
HOSTNAME:/LOCALPATH/ /
The "-e" option is built from $Conf{SshPath} and $Conf{RsyncSshArgs}. The
rest of the configurable arguments (after -e) come from $Conf{RsyncArgs}.
As Holger mentions, either the main config.pl didn't get updated for some
reason (did you install by running configure.pl?) or you have per-client
overrides that the upgrade doesn't automatically update for you.
The default settings in 4.0 for these config variables are:
$Conf{RsyncArgs} = [
'--super',
'--recursive',
'--protect-args',
'--numeric-ids',
'--perms',
'--owner',
'--group',
'-D',
'--times',
'--links',
'--hard-links',
'--delete',
'--partial',
'--log-format=log: %o %i %B %8U,%8G %9l %f%L',
'--stats',
$Conf{RsyncSshArgs} = [
'-e', '$sshPath -l root',
];
