Ok, I finally found and tracked down my problem.
I'm using BackupPC on Ubuntu 7.10, which installs BackupPC 3.0.0.
Turns out, changing the TopDir location does NOT change the location
of the pool files - they are hardcoded to live in /var/lib/backuppc.
According to here:
http://backuppc.wiki.sourceforge.net/change+archive+directory
The solution is as follows:
"The archive directory is defined by $TopDir in config.pl.
Unfortunately, the current version honors this value for host data,
but the pool directories continue to use the default path that is hard-
coded at install time. For now, in addition to changing config.pl, you
will also need to edit lib/BackupPC/Lib.pm, and change the value in
$topDir='/path...'."
Changing this file to point to my desired backuppc home dir solved the
link problems, and my backups now run error-free.
Thanks for all the help!

Ok, I freely admit that I'm in over my head here... I am NOT a perl
programmer. However, here is the method that is puking when trying
to create the links:
sub MakeFileLink
{
my($bpc, $name, $d, $newFile, $compress) = @_;
my($i, $rawFile);
return -1 if ( !-f $name );
for ( $i = -1 ; ; $i++ ) {
return -2 if ( !defined($rawFile = $bpc->MD52Path($d,
$compress)) );
$rawFile .= "_$i" if ( $i >= 0 );
if ( -f $rawFile ) {
if ( (stat(_))[3] < $bpc->{Conf}{HardLinkMax}
&& !compare($name, $rawFile) ) {
unlink($name);
return -3 if ( !link($rawFile, $name) );
return 1;
}
} elsif ( $newFile && -f $name && (stat($name))[3] == 1 ) {
my($newDir);
($newDir = $rawFile) =~ s{(.*)/.*}{$1};
mkpath($newDir, 0, 0777) if ( !-d $newDir );
return -4 if ( !link($name, $rawFile) );
return 2;
} else {
return 0;
}
}
}
The line:
return -4 if ( !link($name, $rawFile) );
is where the problem occurs. How do I get the contents of $name or
$rawFile to spit out into the log so I can see for sure where it is
trying to link to/from?
I'd like to try manually creating the link as Les suggested as the
backuppc user, but I'm unsure what to pass to ln in the shell.
Here, again, is the error from my log:
2008-02-27 15:03:50 BackupPC_link got error -4 when calling
MakeFileLink(/mnt/plump/backuppc/pc/192.168.0.8/6/f%2fUsers%2fkathy/
attrib, 3a473beda0c8d3677d88cd783aa4cc68, 1)
I'm just unsure how to take the parameters that are passed to
MakeFleLink and convert them into whatever is passed to the link
call later.
Thanks!

Pool is used if you don't have compression enabled, cpool if you

directory tree so that hardlinks work between them. If you are
getting errors making the links, check that you have space (df)
and inodes available (df -i), and that the directory is writable
by the backuppc user.
Hmm....Something is definitely up with my inodes:

I notice that all my disks that are ReiserFS do not list any
inode info at all... is ReiserFS the problem, then? Should I
change the backuppc disk to be ext3?
Reiserfs creates inodes as needed so that's not a problem. Just
look at your logs and if you still see 'unable to link' errors, try
to find the reason. Trying execute the same ln command as the
backuppc user might give you some sort of error message.
