Purpose

This article documents antivirus exclusions that have been found to help prevent antivirus software from interrupting Veeam Backup & Replication communications with components such as proxies and repositories or with the guest OS of VMs that are being backed up or replicated.

Solution

Antivirus Exclusions:

Folders on the Veeam Server:

  • C:\Program Files\Veeam
  • C:\Program Files (x86)\Veeam
  • C:\Program Files\Common Files\Veeam
  • C:\Program Files (x86)\Common Files\Veeam
  • VBRCatalog ( [HKLM\SOFTWARE\Veeam\Veeam Backup Catalog] CatalogPath value)
  • NFS (Configured in each repository, stored in [HKLM\SOFTWARE\Wow6432Node\Veeam\Veeam NFS] RootFolder value)
  • C:\VeeamFLR\*
  • C:\Windows\Veeam
  • %programdata%\Veeam

Folder on Guest OS for VSS:

  • C:\Windows\VeeamVssSupport (folder might be missing, depends on backup job settings)
  • C:\Windows\VeeamLogShipper (folder might be missing, depends on backup job settings)

Folders on VMware Backup Proxies and CIFS Repository Gateway:

  • C:\Program Files (x86)\Veeam
  • C:\Windows\Veeam

Folders on Windows Repositories:

  • C:\Program Files (x86)\Veeam
  • C:\Windows\Veeam
  • %programdata%\Veeam
  • *Also include the path the backup files*
  • *Also include the path to 'ArchiveIndex' for capacity tier*

Folders on WAN Accelerator:

  • C:\Program Files (x86)\Veeam
  • C:\Windows\Veeam
  • *Path of WAN cache on WAN accelerators*

Repository Files:

  • VeeamAgent.exe

  • *.vmdk
  • *.flat
  • *.vbm
  • *.vbk
  • *.vib

Due to the complex nature of antivirus software some additional exclusions may be needed.
If your antivirus has a logging or history system please review this to see actions it may have taken that may affect Veeam Backup & Replication operations.
