Hi Loure
As MYOB Business is cloud based files can be accessed from any device through an internet browser. As such, it's not possible to take a back up or restore a back up in an MYOB Business file. To enter adjustments in your file the accountant would need to be added as a user/advisor, they can then sign in to the file and enter the required data.
Back up files would be for AccountRight company files and cannot be accessed through MYOB Business.
Please let me know if you need further help.
