Cause
Cybereason generates random files with common end-user type file extensions (.jpg, .xls, .mp3, etc.) and distributes them throughout User profile and other folders to assist with detecting and preventing Ransomware attacks. These files cannot be accessed by design and generate the following entries in File System backup logs.
Resolution
A common attribute of these files is they are hidden (-h attribute). Use the --nobackuphidden flag to exclude these files. Add it to local avtar.cmd or to the dataset.
Additional Information
Any files with the -h hidden attribute will be excluded.
