I thought you didn't do offsite backup. I think you mentioned that you have an upload of 5 megabits/second. Hers is 30-90 kilobits. Takes her up to 170 times longer than it would take you. I.e. if your database is 200 MB, it would take you about 5-6 minutes to backup at 5 megabits/second. At 30 to 90 kilobits, it can take anywhere from 5 hours to 15 hours.
This is why AC needs to setup an incremental system for backups lol.
