Database Backup Blues

Last night I setup 3 new database backup schedules and noticed that only one of them backed up at the correct time. It’s now 1.18PM here in Australia and the Dropbox backup seems to be stuck at 91% when it should have finished early this morning and one of them hasn’t even started when it should have completed by 7.00AM.
Thanks for any suggestions about what I should do.

Maybe Roon can do only one backup at a time and some internet connection problem to Dropbox, etc. caused that one to pause or stall.
