If you are running an AntiVirus software or a file-scanning software, we do recommend excluding a couple of directories used by VM Backup in order to ensure that it's operation remains undisrupted.
We do recommend excluding the following:
- all onsite backup drive directories
- all offsite backup drive directories
- C:\ProgramData\Altaro on the Management and on the Hyper-V hosts
- C:\Program Files\Altaro on the Management and on the Hyper-V hosts
Also, if you relocated the temporary files ensure to exclude that directory as well.
