Integrated BMR and image-based BMR comparison

The following table provides a high-level comparison of integrated and image-based hot bare metal recovery.

Item

Integrated BMR

Image-based BMR

Recovery Time Objective (RTO)

Faster recovery time than with image-based BMR.

Slower recovery time than with integrated BMR.

Recovery Point Objective (RPO)

More recovery points available since you restore from any eligible file-level backup.

Fewer recovery points since you restore from a bare metal backup only.

Recovery types

Supports physical-to-virtual (P2V), virtual-to-physical (V2P), physical-to-physical (P2P), and virtual-to-virtual (V2V) DR.

Supports physical-to-virtual (P2V), virtual-to-physical (V2P), physical-to-physical (P2P), and virtual-to-virtual (V2V) DR.

Dissimilar restore of Windows Vista/Server 2008

Yes, restore of Windows Vista/Server 2008 to dissimilar hardware is supported on appliances running Unitrends version 7.5 and higher.

Yes, restore of Windows Vista/Server 2008 to dissimilar hardware is supported.

Dissimilar restore of Windows XP/Server 2003

No, restore of Windows XP/Server 2003 to dissimilar hardware is not supported.

Yes, restore of Windows XP/Server 2003 to dissimilar hardware is supported.

On-system retention

More on-system retention due to eliminating bare metal backups.

Less on-system retention due to bare metal backup storage.

ISO image/boot disk

Standard 32- and 64-bit ISO images used for most Windows clients; available on the Unitrends system.

Separate ISO required for each Windows client; ISOs must be created manually with the Unitrends bare metal agent.

Bare Metal Interface

Simplified wizard interface enables DR to the desired point-in-time using a single process, decreasing overall recovery time. Leverages WinPE 4.0 for all Windows clients.

Two dialog-based interfaces (one WinPE 1.5 for older clients, one WinPE 2.0 for newer clients), cannot perform DR in a single process.

Target disk size

Supports recovery of original Windows client to a smaller disk size.

Must recover to a disk of an equal or greater size than that of the original client.

UEFI-based clients

Supports recovery of UEFI-based clients.

Cannot recover UEFI-based clients.

GPT-partitioned clients

Supports recovery of GPT-partitioned clients.

Cannot recover GPT-partitioned clients.
