Could this be related to an smbclient problem reported earlier
where incrementals fail authentication? I'm attaching the
concluding email from that thread.

Thanks, Les, for the reply. I've been busy, and that's one of the
things I've checked.
What it comes down to, is....Samba 3.0.23-1 broke my system. I'd setuid
the smbclient and mount.cifs commands on disk; it complained until I
removed that permission bit from those files. That didn't fix the
backuppc problems (though I held my breath as I tested again).
[It turns out smbmnt is /not/ based on "libsmb" - which is why samba was
complaining and bailing - nothing based on this library can be suid
anymore, fyi...so I simply setuid that executable. Bob's your uncle.]
Prepare for this upgrade, folks! They're trying to improve the world
over at Samba-land, and we're gonna be hurtin' until we figure all this out.
I still have no idea why logins only fail on incrementals.
I've upgraded to BackupPC v3.0.0beta0, but the smbclient command lines
for SMB-based incremental, full, and restore are the same as in past
versions :-/ No satisfaction there. I tested anyway, but you already
know how that story turns out.
I've been through the entire release notes for this version of Samba -
my prev version was 3.0.14a-2 (fedora core-4) - and there are literally
thousands of changes. My eyes are bleeding. Nothing jumped out at me,
no eureka moment...
<rant>We need a Linux kernel approach for samba, it would seem, where
even numbers and odd numbers are used for stable versions and for
massive changes, respectively - and those unstable versions are not
pushed out to every computer in the world! </rant>
Is anyone else running this version of samba? If so, is it working for
you? I'll work this problem from both ends....if anyone has any info, I
would be grateful.
I'd go back, but the idea is that sofwtware changes are *for the
better*, and the Samba guys have as good a rep as anyone. I'm going to
try to fix this before I punt and downgrade.
I'm simply running a full backup on each machine that has not been
backed up for the last week or so....! I would have punted days ago if
I didn't have this escape hatch.
Complicating things is the fact that I have this half-a-terabyte volume,
and it's 95% full, because I have it retaining nearly every backup I've
ever done....so I really reduced the retention figures, and now
BackupPC_trashClean is going nuts - it's already returned nearly 4
GB...and I have this feeling it'll be running all night - or all weekend :-)
More as it happens....
Thought for the day: Fedora makes "trailblazers" of us all, I think,
when you have an untested combination of software - like BackupPC and Samba!
