How do you call DeltaCopy from the Backuppc Server?

With Rsync. XferMethod = rsyncd

The incremental backup runs inludes all files, but only every other day.

What did you mean with "but only every other day" ?

Well, not every incremental run backs up all files. For example on host 
eddie ,see beow, incr backup# 333 is ok but 334 is not, it touches all 
files, and I believe it shouldn't? I mean I know all of these files 
haven't changed.

Unless you are doing different incremental levels, the two runs should 
be exactly the same from the server's perspective, doing the rsync 
comparison against the save full run as the base.  Can anything have 
changed on the files (timestamps, owner, etc.)?  I'm not sure what 
metadata it actually checks on a windows client or whether there is 
anything different about DeltaCopy in this respect, but rsync will show 
those differences as an update without spending any time copying the 
unchanged content.   But even then it doesn't make sense that #335 is 
normal again unless you have set incremental levels since it should 
still be checking against the last full.

I find it highly unlikely that all of the files have changed as this is a recurring pattern which is the same on these two clients. The only thing I can think of is that Deltacopy (or rsync) misinterprets something, perhaps after a reboot or sleep on the client, but that seems also unlikely.

The $Conf{IncrLevels} is left blank in the config file. The default is 1 I believe. Could that cause the problem?

Also, the setting for XferMethod on localhost is tar, not rsyncd, which might explain why there is no problem with the localhost. So it seems the rsync is the lowest common denominator.
