Avoid antivirus interference with Phoenix DRaaS program or process
Overview
Antivirus programs may sometimes lock actively used files or folders of other applications.
If any such application locks the Phoenix DRaaS program or process, it may result in corruption or unexpected behavior. Hence, it is highly recommended to add exclusions for the Phoenix DRaaS program or process.

Steps to be performed on the source VM when DR failover is failing due to Antivirus
- Whitelist above files with the absolute path on the antivirus.
- Run the VM backup.
- Update the DR copy.
- Perform the DR failover (with DEBUG_TW = True in the AWS proxy).
Purpose of each Service:
The Druva executable are basically used to control the flow for failover like maintaining the installation order, Upload logs ,Send SQS messages and getting the non boot volumes / disks online .
- C:\Druva\Model\cli.exe
- C:\Druva\Service\rmservice.exe
- C:\Druva\Model\run_model.bat
