Bin functionality was built-in originally with SharePoint 2007 and is
available in SharePoint 2010 as well. This functionality is the first
line of defense for restores, enabling end users and administrators to
restore deleted items easily and reduce overheads associated with
restore operations and loss of productivity.
Understanding the Two Stages of the Recycle Bin
As in SharePoint 2007, the
Recycle Bin functionality in SharePoint 2010 remains the same: two
staged. When an item is deleted, it goes through both Recycle Bins
before being deleted completely from the database.
The first Recycle Bin, as shown in Figure 1,
is at the site level. This Recycle Bin is available and managed by the
end users of the site. To restore deleted items from the Recycle Bin,
the end user can navigate to the Recycle Bin from the Quick Launch (left
navigation in SharePoint), select the deleted items to restore, and
click Restore Selection. This action restores the deleted items in their

End users see only the items that have been deleted by them. They do not see items that have been deleted by other users.
the end users have not restored the deleted items from the site Recycle
Bin within the retention period (default is 30 days), or have deleted
the items from the Recycle Bin, the items are moved to the secondary
Recycle Bin. This Recycle Bin is at the site collection level, and only
site collection administrators have access to this Recycle Bin to
restore items for the end users, as shown in Figure 2.

Enabling Recycle Bin Functionality in SharePoint
To access the Recycle Bin settings for a particular web application, perform the following steps:
Open the SharePoint Central Administration site on SharePoint 2010 Central Administration.
Select Application Management in Quick Launch.
Under Web Applications, click the link for Manage Web Applications.
Highlight the web application that you want to manage.
The Ribbon will be highlighted.
Click General Settings and select General Settings from the drop-down menu.
Scroll down to the Recycle Bin options, modify the settings, and click OK to save these changes.
The Recycle Bin settings listed, shown in Figure 3, allow for the following options:
Recycle Bin Status— This setting enables the entire web application Recycle Bin, including both stages, to be toggled on or off.
Figure 3. Understanding Recycle Bin settings for a web application.
Delete Items in the Recycle Bin—
This sets the number of days before items are removed from the end user
Recycle Bin. The default value is 30 days. This setting can be altered
with a number of days of your choice, or it can be toggled to never
delete items from the Recycle Bin.
Second Stage Recycle Bin—
The Site Collection Recycle Bin, also known as the Second Stage Recycle
Bin, can be either turned off or configured to be emptied after it
reaches the specified percentage of the web application’s quota. For
example, if the web application has a quota of 500MB, a setting of 50
percent enables up to 250MB of data to be stored in the Second Stage
Recycle Bin, increasing the effective quota of the web application to
750MB. This setting can be changed to a different number up to 100
percent or can be toggled off.
These settings should be
altered only after analyzing the usage pattern of the Recycle Bin at the
site level, number of requests received for Second Stage Recycle Bin
restore, and the type of restore requests received by the SharePoint
administrators. Items retained in the Site Recycle Bin count toward the
quota of a site collection, so this setting has to strike a balance
between the number of days and the site collection quota. Similarly
settings of 100 percent for the Second Stage Recycle Bin would mean that
the size of site collection would be twice as much in the content
Recycle Bin had been introduced in SharePoint 2007 and has proved to be
a value add, not only for the SharePoint administrators but also for
the end users. The Recycle Bin helps reduce SharePoint restore
operations, business continuity, and IT overheads. It is recommended
that the end users be trained in the use of the Recycle Bin.
