QB Issue Resolution:
The backup option is File->Backup. If you have not configure the preferences for the backup this will open the preferences the first time you try it.
In the preferences choose where you want your backup stored (you select a folder and a drive to save it on). If you want it encrypted add a password. If you are using attachments make sure “Back up attached document library” is checked on.
I like to click the automatic backup options, too.
Then choose File->Backup again and you’ll see it make a backup. The backups are stored as Apple Disk Image files (.dmg extension). To restore you double click on one of them and it will open it as a read only disk (like a CD) on your computer.
