My 1320 said "more than a week ago". So I tried doing a manual backup ("backup now"), and after about half an hour it went to 100%, but said that the backup failed and that I should try again. I then deleted the backup on OneDrive and restarted the manual backup, but it seems to take a very long time - stuck on 18% for the past 2 hours - it looks like it is busy backing up Facebook app as it is greyed out on the home screen. Is it normal for the backup to take this long? And I still don't know how often the automatic backup is meant to run?
