Let's see…transferring 10 TB on a 2 MB/second connection (mid-tier here in Singapore) would take 5242880 seconds, or 60 days 8h21m20s assuming no drops or glitches (doubtful here); it's faster to ship an external drive by SingPost. And a lot less likely to have its bits trawled unnecessarily, with a bit of proper preparation.
Thanks; I'll pass
