<font size=2 face="sans-serif">I have been using backuppc (rsync protocol)
to backup up a Linux web server onto a local server for a number of years.
I recall that data volumes were quite low (about 40MB), regardless
of whether I was doing full or incremental backups. I recently switched
to both a new web server and backuppc server. Early morning traffic
volumes when backuppc runs are much higher than expected - I have seen
volumes as high as 450MB. Full backups appear to drive particularly
high volumes, although an incremental backup after cloning a bunch of MediaWiki
installations also transferred large amounts of data. As far as I
can tell, backuppc itself seems to be working fine and reports that the
most files are identical to already backed up files. </font>
<br>
<br><font size=2 face="sans-serif">Many things have changed. I am
backing up a virtual private server with more files. The backup server
is a 'plug computer' with an ARM processor running Ubuntu 9.04, backuppc
3.1.0 and rsync 3.0.5. The web server is running CentOS 5 with rsync
2.6.9. Unfortunately, the old web and backup servers are no longer
available. </font>
<br>
<br><font size=2 face="sans-serif">I enabled verbose logging and itemized-changes
and ran two full backups. Both logs showed a large number of entries
similar to the following. If I read the line correctly, these files
were transferred, the type is a file, and the remaining attributes are
unknown (possible rsync mismatch). </font>

<br>
<br><font size=2 face="sans-serif">I upgraded the web server to rsync 3.0.5
but that does not appear to have reduced data volumes and the log file
entries are unchanged</font>
<br>
<br><font size=2 face="sans-serif">A 'du' on the web server indicates that
there are about 32MB of files. None of these files have changed recently.

<br><font size=2 face="sans-serif">Any suggestions on how I can debug this
