I am new to salesforce.Recently i have created an application in salesforce Preprod instance which includes both standard and custom objects and created custom fields and some validation rules too.
Now,one of my colleagues is planning to refresh that sandbox.I do not know how to take backup of that app and respective metadata.
Can anyone help me out with the steps how to take backup and how to load back after sandbox refresh.
Your response would be highly appreciated.
Thanks!
