+I derived the estimate from a download rate measured during the *failed* attempt, which was running

 Its offsite archive is **14.46 GB**. At the ~125 MB/min restore rate measured on that box, an
 unattended offsite restore-test there is a **~2-hour** operation that will now run roughly every
 other day, holding the heavy-operation gate throughout and so deferring backups behind it.
