SUMMARY
Does Unitrends support backup of zones?
ISSUE
Solaris has a feature for virtualization called zones, previously called containers.
See this documentation for more information:

You can use zones to create private execution environments within a single instance of the Oracle Solaris 10 OS. Each environment has its own identity that is separate from the underlying hardware. Each environment behaves independently as if running on its own system, making consolidation simple, safe, and secure.
Unitrends can protect the global zone, otherwise known as the default OS. The non-global zones will need to be protected by backing up the default OS.
