below the speed I have not seen!
20 GB on the phone back-up for 6 hours and only 93% is ready.
250 GB on the computer predicts to finish no earlier than a day.
in the applications for the phone and the computer does not configure the backup time.
in the phone only files are backed up. calendar, contacts, calls, sms and more can not save.
there is no access to backups on the site through the browser.
I do not recommend to use.
