Review the Prerequisites and Considerations

Verify if you have completed the following prerequisites:

• Log into the Console.

• Install the server component and create Data Stores if you want to store the backup data to recovery point servers.
• You have a valid recovery point to create a virtual standby machine. The recovery points can be from one of the following tasks:
• Backup, Agent-based Windows
• Backup, Host-Based Agentless
• Replicate
• Replicate from a remote Recovery Point Server

• Back up the full machine to enable the Virtual Standby task. You cannot create a Virtual Standby task if the backup is not a full backup.
• Verify if you have the minimum permission to perform required VSB tasks. For more information, see Minimum Permission Required for VSB tasks.
• Virtual Standby is not supported for Linux sources. To view a list of supported operating systems, databases, and browsers, see Compatibility Matrix.

Considerations:

• Virtual Standby uses thin-provisioned disks for vSphere.
• Virtual Standby uses dynamically expanding virtual hard disks for Hyper-V.
• VMware uses separate machine for monitor server with agent installed.
• Hyper-v itself acts as monitor server with agent installed.

Note: As a best practice, we recommend excluding files from antivirus scanning to make sure that the virtual standby works properly. For more information, see Exclude files from Antivirus Scanning.
