When did I say I wanted you to give away your software? I didn't. I said
I was reticent to use or encourage its use b/c of the role it plays in
an infrastructure and it being closed source. I never expect you to give
anything away, nor did I ask that.

What facts did I make up? You are a small company. Small companies have
a hard time weathering difficult economic conditions. I need backups to
be restore-able for years - sometimes during economic downturns. I don't
want guessing games about the viability of the backup mechanism.
Moreover I don't have any attachment or interest in TSM - it is what we
were saddled with in the group I work with at duke. I'd prefer if we
were not using it, either. I think backup solutions should be like
document storage solutions - not given to the whims of a single company
but based on vendor-independent standards and in the best of all worlds
an open-source developed and maintained solution.
openafs is open source - it's the only only functional implementation of
an afs server left that I know of. It would make sense that it would
have a backup mechanism coupled to it that was also open source.
I never said your product was not good or functional and I will not say
such things. It looks like TIBS would do a great job my concern is with
the other realities that come with relying on closed-source-software.
When IBM announced dropping AFS support in TSM I said the exact same
thing about IBM to our folks reviewing our contract.
I worry about the impact a company's decisions or the markets discretion
will have on the viability of me to maintain my backups and therefore my
users ability to get to their data.
What's 'Not cool' here is you deciding that no one is allowed to present
doubts and concerns about the longtime functionality of relying on
closed source software solutions especially those from small companies
and especially when our economy is taking a swing into a downturn.
So let me make sure my point is abundantly clear:
"In my opinion closed-source software that does not rely on a public
standard with multiple implementations is a bad choice for backup
solutions. More so from small companies or 'unique' implementations."
The only reason Teradactyl was mentioned at all was b/c of it being an
example of the above.
I have a whole other set of criteria I use when evaluating the viability
of open-source backup solutions. They have to do with the viability of
the project and the commonality of the implementation.
