Backup stores backup copies of files that were deleted or modified during disinfection. A backup copy is a file copy created before the file was disinfected or deleted. Backup copies of files are stored in a special format and do not pose a threat.
Backup copies of files are stored in the folder C:\ProgramData\Kaspersky Lab\KES.21.19\QB.
Users in the Administrators group are granted full permission to access this folder. Limited access rights to this folder are granted to the user whose account was used to install Kaspersky Endpoint Security.
Kaspersky Endpoint Security does not provide the capability to configure user access permissions to backup copies of files.
Sometimes it is not possible to maintain the integrity of files during disinfection. If you partially or completely lose access to important information in a disinfected file after disinfection, you can attempt to restore the file from its backup copy to its original folder.
If Kaspersky Endpoint Security is running under the management of Kaspersky Security Center, backup copies of files may be transmitted to the Kaspersky Security Center Administration Server. For more details about managing backup copies of files in Kaspersky Security Center, please refer to the Kaspersky Security Center Help system.
