You might encounter QuickBooks Restore Failed Error while trying to restore a backup of a QuickBooks company file or because you might have included special characters (/ < >! $) while naming your company file name. Other factors include the backup that you restored being over an existing company file; the probability is high that you have restored the backup from a USB flash drive to a network drive (Error -6189, -816), or you might be using a damaged or corrupt company file. The backup was created in a newer version of the QuickBooks desktop application led to this issue.
