SharePoint has lot of features and in any organization data grows day to day. At end of the day we see huge and huge data which is unusable or data grown beyond the estimation or something which is unmanageable. The sites will be created as we need but we don’t delete them when we don’t need it.
You can use site policies to help control site proliferation. In SharePoint 2013 we have couple of options to control the site policy. Below is the site policy with the available options.
The MSDN article has very detailed description of the options mentioned here. These policies will help us to resolve the site management issues we face in large organizations.
