Before you add a WAN accelerator, check the following prerequisites:
- You must assign the WAN accelerator role to a Microsoft Windows server (physical or virtual). The WAN accelerator role can be assigned to backup proxies and Microsoft Windows backup repositories configured in the backup infrastructure.
- You must use 64-bit Microsoft Windows machines as WAN accelerators. Veeam Backup & Replication does not support 32-bit versions of Microsoft Windows used as WAN accelerators.
- WAN acceleration operations are resource-consuming. When assigning the WAN accelerator role, mind available CPU and memory resources of the Microsoft Windows server. It is recommended that you assign the WAN accelerator role to servers with 8 GB RAM and more. Otherwise, the WAN acceleration process may fail.
