Not that it's used by amanda for anything, but your speed seems awfully
slow. I don't know if that's a symptom of amtapetype or not (LTO3 drives
are fast compared to *hard drives*, never mind your standard tape drive),
but to get my LTO3 drives to run anywhere near their rated speeds I had
to use a blocksize > than amanda's default 32K. To do *that*, you'll need
to use the --with-maxtapeblocksize flag at configure time. I'm using 2M
blocks.
Would it be a good idea to round any of these values down?
Generally it's not a bad idea to round the tapelength down a bit,
especially if you find yourself hitting EOT frequently.
