Delete and restore list items and documents
When documents, list items, folders, or even entire lists are deleted, they are simply flagged as removed so that they no longer appear in the site from which they were deleted. By default, all sites in SharePoint 2016 are configured to display deleted items in the site’s Recycle Bin for 30 days. The Recycle Bin provides a safety net when you are deleting documents, document sets, list items, lists, folders, and files. If the user hasn’t restored the deleted item in that time period, it is then permanently expunged from the database. If the user empties the Recycle Bin before the 30 days have elapsed, the deleted item is still available to a site collection administrator from the site collection’s Recycle Bin.
However, the total size of the deleted items must remain below a specified percentage (50 percent by default) of the total size that a site is allowed to consume (the site quota). If a newly deleted item causes the total to exceed the configured size allowed by the SharePoint central administrator, the items that were deleted first are purged even if 30 days have not elapsed, to make room for the newly deleted item. In this way, SharePoint administrators can make disaster recovery plans based on the Recycle Bin’s allowable total maximum size. Of course, a SharePoint administrator can configure the number of days that the Recycle Bin retains deleted items, ranging from the default 30 days in SharePoint 2016 to a specific setting for a number of days, or to “never retain deleted items” or “never remove deleted items.”
