looking for dar/libdar references and use cases

Dear dar/libdar users,

I'm looking for use cases over the original target dar was initially 
built for (home backup on CD/DVD). I remember some recently mentioned 
HPC (High Performance Computing) use case, some others I think, but 
that's quite long ago now, were using dar for archiving large volume of 
telescope pictures...(?)

My objective is to add a page on dar's home page listing original, 
unexpected uses of dar/libdar. This may be directly using dar or through 
a frontend/external application (SaraB/Baras, gdar, dar-backup...)
or from your own code in C/C++, Python or even now D language.

If you're interested in that project, you could for example give the 
following infos:

- company/username/or stay anonymous if you prefer
- at what time this use case started (just the year is fine) and 
eventually ended
- use case description
- typical size created for backups/archives
- media used (disk/tape/cloud...)
- key dar/libdar features/differentiators that lead you choosing dar for 
this use case
- everything else that does not fit in the previous items
----
I will then make a 7 columns table of this info, if there enough entry 
for it makes sense, of course.

I have no objection to make advertisement to private or public 
organization in return, thus you are welcome to add an URL/link to your 
organization or home page.

Cheers,
Denis
