# Estimating System Requirements

You can use the DR Sizing Calculator to estimate Recovery Time Objective (RTO) for periodic replication, the number and size of VMs, MediaAgents, and other infrastructure assets required to use disaster recovery in your environment.

## Procedure

1. Go to the DR/Replication Sizing Calculator.

   The DR/Replication Sizing Calculator appears.

2. Enter the number and size of VMs in your environment, your name, your email address, and then click OK.

3. The RTO Information page appears.

4. In the Periodic Replication VMs box, enter the number of VMs that you want to configure for periodic replication. The numbers you enter in these boxes should add up to the total number of VMs in your environment.

5. In the Rate of Change (in %) box, enter the amount of difference in data you expect between the source site and the DR site for every incremental replication job, and then click OK.

   A summary of the requirements for periodic replication appears. This information is also sent over an email.
