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. |
|
Restore of Windows Server 2016 |
Yes, restore of Windows Server 2016 to identical or dissimilar hardware is supported on Linux CentOS 6 appliances running Unitrends version 9.2 and higher. |
No, restore of Windows Server 2016 clients is not supported. |
|
Dissimilar restore of Windows Server 2012 |
Yes, restore of Windows Server 2012 to identical or dissimilar hardware is supported on appliances running Unitrends version 7.5 and higher. |
Yes, restore of Windows Server 2012 to identical or dissimilar hardware is supported. |
|
Dissimilar restore of Windows Vista/Server 2008 |
Yes, restore of Windows Vista/Server 2008 to identical or dissimilar hardware is supported on appliances running Unitrends version 7.5 and higher. |
Yes, restore of Windows Vista/Server 2008 to identical or dissimilar hardware is supported. |
|
Dissimilar restore of Windows Server 2003 |
No, restore of Windows Server 2003 to dissimilar hardware is not supported. Restore to identical hardware is supported. |
Yes, restore of Windows Server 2003 to dissimilar hardware is supported for some distributions. See the Compatibility and Interoperability Matrix for details. Restore to identical hardware is supported for all supported distributions. |
|
Dissimilar restore of Windows XP |
No, restore of Windows XP to dissimilar hardware is not supported. Restore to identical hardware is supported. |
No, restore of Windows XP to dissimilar hardware is not supported. Restore to identical 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-bit 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. |
