XFS was developed by SGI as a media system, and its design is optimized
for long streaming reads and writes.  Nevertheless, it performs enough
better than ext4 at short random I/O that both Oracle and PostgreSQL
recommend it over ext4 for database applications.

And that's for a usage type that it is NOT optimized for.  Bacula's OS
workload for storage is long, streaming reads and writes.  Exactly what
XFS *IS* optimized for.

You should be able to draw your own conclusions...
