Frank, the answer to your question about the Avamar is "no", because other than
replicating to another Avamar unit, there is no way to move or copy the data
once it lands on the Avamar server. The entire architecture is designed to put
it on disk, replicate it to a separate unit over IP, and leave it alone until
it expires. Before EMC bought them, I know of at least two approaches that
Avamar (the company) was trying to float to address the need to get the
backed-up data on to other media, but both are deprecated or unavailable as of
the current version (4.x)
