Hi,

Thanks for sending out an official response to this. I'd not crossed the above
mentioned blog post before my initial email to this list.

Yes, I understand that freezing a single file is extremely inconvenient and
would make duplication a pain/expensive.

What I had is mind is something like "Backup up 200G of photos that I have in
my home NAS. I'll only want these if my NAS blows up, which will hopefully be
never."

For the rest of my stuff and files I might want access to, tarsnap works fine
for me.

Cheers, and thanks for the great service! 👍
