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! 👍 -- Hugo Osvaldo Barrera A: Because we read from top to bottom, left to right. Q: Why should I start my reply below the quoted text?
