Review the Restore Prerequisites and Considerations
Verify that the following prerequisites exist before performing a restore:
- You have a valid recovery point available to restore from.
- You have a valid and accessible target Virtual Center/ESX or Hyper-V server to recover the virtual machine.
- Review the Compatibility Matrix which provides the supported operating systems, databases, and browsers.
Review the following restore considerations:
- Arcserve UDP Agent (Windows) only allows one restore job to run at the same time, while Arcserve UDP allows multiple restore jobs to run at the same time. If you attempt to launch a restore job manually, while another restore job is running, an alert message opens informing you another job is running and requests you to try again later.
- If the Recover VM destination is Windows Server 2008 R2 then the source backup VM should not contain VHDx disks, which are not supported on the Hyper-V server (Windows Server 2008 R2).
- If the Recover VM destination is Windows Server 2008 R2 or Win2012 then the source backup VM's sub-system type should not be generation 2 (which was introduced in Windows Server 2012 R2), and is not supported on the Hyper-V server (Windows Server 2012/2008 R2).
- You cannot restore a VM to an ESXi 5.5 machine if an x86 OS machine is used as a proxy server. In this case, you will get an error message on the recovery dialog. The reason is that, VMware VDDK 5.5.x is required to interact with ESXi 5.5, but, if the proxy server is an x86 OS, VDDK 5.1.2 is used by Arcserve UDP Agent (Windows) because VDDK 5.5.x is not supported on an x86 OS.
