QB Issue Resolution:

QBO does not have a back up at all from the user perspective.

Intuit backs the servers up, but can not restore your file from that back up

the make local copy provides you with a copy that does not contain all financial information, and can not be used locally, nor can it be used to upload to the old or a new QBO file

the export to desktop provides you with a file that must be opened in desktop within 10 days , and the file has known problems, some things do not export, inventory exports as service items with no history, these known problems have existed for over 5 years

About all you can do is create a general ledger report and export to excel or print it – since QBO has limited reporting abilities in terms of data being reported on you may have do several reports for various periods of time

I am unclear whether the journal report can be accessed by the user, you may need an accountant to log in and do it
