folder which contains your current Quicken data file, e.g.
\Documents\Quicken\Backup. Set it to create a backup after running Quicken 
times and to keep  (or more, your choice) backup copies.
The file name for Automatic Backup files contains a date and time stamp as part
of the file name, e.g. QDATA-2020-03-22.PM03.45.QDF-backup

device so that it looks something like this: E:\Quicken
or use the Change button and work your way through the dialog.

Add Date option you only have 1 backup copy which is overwritten every day ...
and that may prove bad in a problem recovery situation.
Allow this backup to
run to save the changes made on the screen.
Of course, once in a

your discretion, to avoid filling up your USB device.
One can never have
enough backups of a Quicken data file. BTDTGTS!
