Made a little progress on this...  I finally noticed the "Last bad XferLOG" link in the CGI interface.

It seems to be a sudo-related problem - it's prompting for a password.  Either

a) FreeBSD uses a different syntax/version in sudoers, so my NOPASSWD line isn't working, or

b) FreeNAS does some kind of weird shuffling of the root filesystem, apparently running it off a ramdisk or something like that and keeping the "real" persistent root filesystem somewhere else, so perhaps the sudoers change is getting lost somewhere in the insanity and not taking effect as it should.

I have a test install of backuppc up and running, and backing up a half-dozen Debian servers with no problems.  Now our NAS admin has asked me to add a freenas machine to the test, and it's just giving me "fileListReceive failed" whenever I try to run a backup.

I've verified that I can ssh in as the bpc user without problems, and determined that freenas puts rsync in a different place than debian does, so I created a file at /etc/backuppc/thisnas.pl containing

$Conf {RsyncClientPath} = '/usr/local/bin/rsync';

then forced bpc to re-read the configuration and tried again, but still "fileListReceive failed".

What's my next step for resolving this?  Is it possible to get more detailed information in the bpc logs than just "fileListReceive failed"?

Note that I do *not* have root/sudo access on the freenas machine, so there are logs I can't check there.  I instructed the nas admin to add the line

backuppc  ALL=NOPASSWD: /usr/local/bin/rsync --server --sender *

to sudoers, and he has done so, so bpc should have sufficient sudo capability to run, even though I'm not an admin there myself.
