How to exclude NovaBACKUP from Windows Defender Antivirus to speed up backups
Occasionally, certain Anti-Virus software may incorrectly flag or interfere with your NovaBACKUP software from properly running. This can result in a failed backup job, unusually slow backup speed (transfer rate), failure for the application to start entirely, or the inability to see destinations to backup your files to. Please also confirm no files shown here have been quarantined by your Antivirus software if you cannot find the file in the listed location.
This guide discusses how to exclude NovaBACKUP processes, file types, and program folders from Windows Defender Antivirus, to speed up backups. We have an alternate guide on the subject of how to exclude the required items from other anti-virus software here.
