How can I create a sandbox in salesforce?

Hi Laveena,

When you create a sandbox, Salesforce copies the metadata from your production org to a sandbox org.

you can create a sandbox as following

• From Setup, enter Sandboxes in the Quick Find box, then select Sandboxes.
• Click New Sandbox.
• Enter a name (10 characters or fewer) and description for the sandbox.
• Select the type of sandbox you want.
• Select the data to include in your Partial Copy or Full sandbox.
  • For a Partial Copy sandbox, click Next, and then select the template you created to specify the data for your sandbox.
  • For a Full sandbox click Next, and then decide how much data to include.
• To run scripts after each create and refresh for this sandbox, specify the Apex class you previously created from the SandboxPostCopy interface.
• Click Create.
