We just did an evaluation of Storage Migrator, and I've been looking
also at other archiving solutions, including NetBackup's archiving

I tried to find the answer to this exact question, with no solid answer.
I was told by our sales rep that 30 years is the approximate lifespan of
DLT media. I wouldn't heavily rely on this.

No, you're probably not missing anything as I've yet to find a good true
archiving package. Keep in mind that Storage Migrator is an HSM
(hierarchal storage manager), NOT an archiving solution. Data can still
be modified, and if you are considering using it for long-term storage
of important data, keep in mind that its an extra layer of complexity.
On top of it all, its newer pricing scheme makes it more expensive than
disk, unless you have a *lot* of data. NetBackup has an archiving
functionality, but it may not fit your needs well. Its limits of
retention periods, lacking the ability to selectively destroy data (for
govt. documents, this is very important), and weak meta data search
capability made it a no-go; it works great for backup though!

Finding a true archive solution has been on my backburner for a while,
but a solution I found that *may* be close to what you are looking for
is this: http://www.flexstornet.com/html/archive.html. I haven't tested
this or anything, so I don't endorse it, but it somewhat matches your

Something I think is novel & interesting is perhaps to archive data to
DVD-RAMs or even CD-Rs (try http://www.luminex.com/. They only hold
about 5 Gig each, but their shelf life is *way* longer than tape. The
problem is to find a solution to catalog the data to a database reliably
and also to schwerp the data out to the media you want.
Hope this helps.
