HI Sir , How to Online Quick Books Back Up

Hello,

If you have QBO Advanced, you can use the Online backup feature that is included.  It allows you to backup a copy of your online file that can be restored later.  It also does automatic backups as "snapshots" so you can restore to a previous time.

If you are not using QBO Advanced, use this 3rd party app.
