I have just changed to using MYOB online after running it locally for many years and I am finding it hard to believe that such a basic data management tool is not available, even after being "suggested" 4 years ago.
Being able to restore to a backup from the previous day has saved my businesses multiple times over the years and I am currently having to resort to getting my staff to manually run a backup each day, taking anything up to 30 minutes out of their working day each time.
It just needs to be something as simple as a command line switch on the local .exe (i.e. C:\...\Programs\MYOB\MYOBAccountRight2017.1\Huxley.Application.exe /BACKUP=C:\LOCAL_BACKUP.ZIP /USER=USERNAME@BUSINESS.COM.AU /PASSWORD=ABC123) that can then be scheduled on the local PC.
Granted, there are security issues in doing it this way by having the username and password written into the batch file or scheduled task on the local PC but there are ways around that.
