Can any one help me in suggesting the way to Backup the Existing Data  and apex code and visualforce pages in Salesforce production before any enhancements  or reinstallation of a perticular new  application takes place (i.e before deploying any changes from Sandbox) .For example if we take a full sandbox when we refresh it from production , full sandbox will be updated with all the data which is there in existing prodution till that date of refreh . Can we do similar refresh of Salesforce production like that and put a backup of that original production data.

Thanks
