@jon while an excellent suggestion you would still have the same problem as @m1sty222 stated in their initial post, namely, importing a backup “changes the Business name on invoices etc. to whatever I have called my last backup” unless you also do what @lubos recommended “go to Settings -> Business Details and enter business name there. Then it will show on invoices no matter what is the name of the business file.”
Also, with your suggestion you could have a “number of backups” control, if you nominate 3 then on the 4th backup the oldest would be deleted
My suggestion would be to use a cloud facility - Dropbox or OneDrive (win10) - for your live Manger files, this way if your computer suddenly drops dead, reconnecting to Dropbox/OneDrive would have all your files re-instated without needing to do backup re-installs.
