Select the type of installation you would like to perform on this machine.
- Client and Server Components—This option installs both the client and server components. The server components are required for systems that will function as a source or target. The server requires an activation code for the service to run. The client does not require an activation code, but it is required to administer this and other Double-Take Availability servers throughout the organization.
- Client Components Only—This option installs only the client components. The client components do not require an activation code, but are required to administer Double-Take Availability servers throughout the organization.
- Server Components Only—This option installs only the server components. The server components are required for systems that will function as a source or target. The server requires an activation code for the service to run.
If you are installing on Server Core, you will only be able to select the Server Components Only installation. You will not be able to run the client components from the Server Core machine. The client will have to be run from another machine.

- Double-Take Availability uses system memory for Double-Take Availability processing. The minimum amount of system memory is 512 MB. The maximum amount is dependent on the server hardware and operating system. Specify the maximum amount of system memory that Double-Take Availability can use and click Next to continue.
- When the allocated Double-Take Availability system memory is exhausted, Double-Take Availability will queue to disk. If you want to disable disk queuing, deselect Enable disk queue. Ideally, you should use disk queuing. Specify the Queue folder, which is the location of the disk queue. By default, the size of the disk queue is set to Unlimited disk queue, which will allow the queue usage to automatically expand whenever the available disk space expands. If desired, you can select Limit disk space for queue and specify a fixed disk space amount. You can also specify the Minimum free disk space, which is the minimum amount of disk space in the specified Queue folder that must be available at all times. This amount should be less than the amount of physical disk space minus the disk size specified for Limit disk space for queue. (See Double-Take Availability queue for additional guidelines on selecting appropriate queue settings.) Click Next to continue.
