SUMMARY
Pros and cons of the different locations of a virtual failover client.
ISSUE
Before setting up your virtual failover client (VFC), you must decide where it will reside.
RESOLUTION
| Considerations | VFC on Recovery-Series appliance | VFC on external hypervisor |
|---|---|---|
| Unitrends system resources | VFC uses a portion of the Unitrends appliance’s processors, memory, and storage. This may impact the performance of regular system functions (such as backups, archiving, replication, deduplication, and purging). Monitor the appliance closely and make adjustments as necessary. | VFC uses the hypervisor’s resources, and running the VFC does not impact performance of the Unitrends appliance. However, running the VFC can impact performance of the other VMs on the hypervisor. |
| On-system retention | On system retention is reduced because a portion of the appliance’s storage is reserved for the VFC. | VFC storage resides on the hypervisor. There is no impact on the appliance’s on-system retention. |
| Use case for the VFC | Use temporarily until you can procure new hardware and perform bare metal recovery. | Use temporarily or use the VFC VM to permanently replace the original Windows client. |
| UEFI-based clients | Cannot recover UEFI- based clients. | Supports recovery of UEFI-based clients. |
| GPT-partitioned clients | Cannot recover GPT- partitioned clients. | Supports recovery of GPT-partitioned clients. |
