What is your concern about frequent log shipping? Is it the overhead? In our
experience New log file is pretty darn quick, although we haven't actually
timed it. It might take some work to figure out exactly what the size of
'nothing' is too.
I haven't tried checking the size or mod date of the .journal, but I would
guess it should work.
But I do recommend mirroring. It's the only way you can provide 24x7 uptime.
And it makes offline maintenance (MSC Compact, Verify, etc) possible. Not to
mention redundancy for DR.
