I just got here, but I'm having a similar issue and I think I may know
the problem, but not how to fix it.
I have the similar situation: DHCP host without DNS but nmblookup works
fine. I can do manual backups just fine but no automatic backups are
happening. The host status is "pings to saruman failed 45 times".
I can't tell why it's failing, but I suspect there's a chicken/egg bug.
The docs say:
1. For each host and DHCP address backup requests are queued on the
background command queue.
2. For each PC, BackupPC_dump is forked. Several of these may be run in
parallel, based on the configuration. First a ping is done to see if the
machine is alive. If this is a DHCP address, nmblookup is run to get the
netbios name, which is used as the host name. If DNS lookup fails,
$Conf{NmbLookupFindHostCmd} is run to find the IP address from the host
name. The file /var/lib/backuppc/pc/$host/backups is read to decide
whether a full or incremental backup needs to be run. If no backup is
scheduled, or the ping to $host fails, then BackupPC_dump exits.
There is a lot of ambiguity here, but as I read it this is what *should*
happen in our situation:
wake up
try to ping host
try DNS (fail)
find host with nmblookup (succeed)
ping IP address
But I'm not convinced it is doing the nmblookup before trying to ping. I
can't seem to get to any debug output to find out just what is failing,
but I can verify that ping by IP and nmblookup both work fine.

There's nothing remarkable about it. All one has to do is hit the
right keys at the right time and the instrument plays itself.
