Ku,
I am afraid I am going to have to question your premise. The EMC
Centera is meant to be an archiving appliance, it isn't like a regular
drawer of disk. It has it's own interface to the storage, and isn't
meant to be backed up. I know that there are companies that provide
solutions to "backup" a Centera, but they are all kludges.
IMHO, backing up an archive device implies a misunderstanding of
why you are archiving to begin with. Backups are to return production
systems back to a running state in the event that the primary running
system has suffered a loss of data for some reason. An archive, on the
other hand, is for data no longer needed for day-to-day processing, but
might be required some time in the future to address a future business
requirement, so as responding to litigation, or IRS records rentention
policies. An archive is usually a cheaper tier of storage, with slower
retrieval characteristics than keeping the data on local disk.
However, it is important to think about the offsite/redundancy
requirements of your archived data. If the data is worth retaining, it
may have sufficient business value to need to survive a site outage. To
that end, the Centera has built-in replication software so it can
replicate seamlessly to another Centera in another location. That is
the best way to provide a DR copy of the data.
We have Centeras at our company, and that is how we do it.

Hello,
we are looking for a DR Tool for EMC Centera Data.
Prefered Platform for this Product should be Unix or Linux.
We are actually using TSM (on AIX) with CBRM (on Windows).
Are there any alternatives instead of e.g. Storefirst Altus?
Cheers,
ku
