The backup transfer has completed from our offsite backup service. I’m now making a second copy of the backup locally before attempting to restore. This should take about 30 minutes.
Once that’s finished, I’ll be attempting to load up the backup as the live system and be back up and running again.
All mail received between Saturday night (late) and yesterday around noon or so will unfortunately be lost. If everything works right, all mail, contacts, calendars, documents, etc, saved prior to Saturday night should be intact.
