We had a meeting yesterday with the Avamar folks at EMC. They mentioned
that it is possible to tape out the data that lands on the Avamar grid
using Networker - did not go into the details of how that is done.

For backing up databases, we were told that there are modules for
Oracle, SQL Server, Exchange etc but there is no licensing costs for
those. The licensing is based on the compressed capacity and not on
features.

We have been invited to see the product in action at the EMC offices in
Warrenville IL.

There are rumors that this will be resolved soon but I don't know how
much to believe rumors.  EMC could jump in here, they do monitor this
list, but they probably won't to avoid committing to anything.

> 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)
