I'm attaching the compressed log. It's 2.5MB uncompressed, that's too
big for pastebin. Please let me know if I should it send it in some
other way.

I got the "low disk space, 200MB remaining" warning on the volume
which had 80GB free initially. Looking at the log file, I guess it's
the initial downloading that fails. But why does it have to download
so much?

I will attach a volume with some 200GB free, point TMP to it, and
restart the restore now.
