[OT] best tape backup system?

Hello and sorry for the OT post, but I felt linux raid administrators
can be also very knowledgable about best-of-breed tape backup systems
for their linux servers.

I admin serveral linux servers with software root raid1/5 and am very
happy about their performance and reliability. Up to now our backup
strategy has consisted in daily offsite incremental rsync backups to
other raid5 linux servers. But I feel a bit nervous about not having
offline backups such as tapes that can be restored in the event our
servers AND their mirrors suffer catastrophic failure or exploitation.

I am considering getting a Sony SAIT 3 with 500G/1TB tapes, which seems
like a nice solution for backuping a whole server on a single tape.

Has anyone used that hardware and can comment on its performance,
linux-compatibility or otherwise?

Is there a better solution out there?

Is it worth waiting a short while for some new upcoming technology?


Thanks for reading and have a nice day!
