I'm designing and implementing a backup regime according to a 3-2-1
strategy.  I've never used tape before but LTO-5 was recommended to me
as being hands-down the best option for long-term backup or archival

LTO-5 has been recommended to me a few times, I didn't ask too many
questions.  I thought it would be better to learn more about what it
is, and about tape backup and archiving in general so that I could
contextualize my questions and understanding better.

As it happens, I'm now seriously looking into tape.  Off the top of my
head I imagine the following things to be the potential attractions of

-   Is LTO-5 somewhat of the standard by which other LTO tape systems
    are judged?

-   Is bang for the buck the primary attraction of LTO-5?

-   Is LTO-5 the best option when a priority is to use open hardware
    and open source drivers to interface the tape drive to the host?

I did some research and got the impression that HP LTO-5 Ultrium RW 3
TB cartridges are more-or-less the standard when it comes to the
actual tapes.

Especially when, for example, a 12-disk array of 8-10 GB HDD's is
hardly uncommon.  Am I completely misinterpreting the way that tapes
are supposed to be used when making backups or archiving such an
array?  Obviously I'm not going implement an intricate differential or
incremental backup or archiving solution until I've got full backups
working properly.

Comments and opinions are well appreciated.
