to end up with an average compression ratio that is very small.
In this case, Bacula reports {\bf None} in the Job report.
+\subsection{Deduplication Optimized Volumes}
+This version of Bacula includes a new alternative (or additional)
+volume format that optimizes the placement of files so
+that an underlying deduplicating filesystem such as ZFS
+can optimally deduplicate the backup data that is written
+by Bacula. These are called Deduplication Optimized Volumes
+or Aligned Volumes for short. The details of how to use this
+feature and its considerations are in the
+Deduplication Optimized Volumes whitepaper.
+
+\smallskip
+This feature is available if you have Bacula Community produced binaries
+and the Aligned Volumes plugin.
