How can we restore the deleted sub site from the Recycle Bin in SharePoint 2007?

There is no direct way to restore the deleted sites from the Recycle Bin in SharePoint 2007. But there was a wonderful tool from Codeplex: Site Delete Capture http://governance.codeplex.com/ to back up sites automatically when they gets deleted, So that we can restore a deleted site collection in SharePoint 2007.

From the SharePoint 2010 onwards, we can restore the deleted sub site from the second stage of recycle Bin. If we delete the sub site, SharePoint will keep the deleted site in site collection recycle bin.

Note: You can find the deleted site secondary recycle bin i.e  “Deleted from end user Recycle Bin”

Is it possible to recreate the deleted site in sharepoint? [Means i have deleted a  site(http://ab.com) and trying to recreate with the same]?

Sol: In MOSS2007, When you delete a Site from the site settings it is deleted permanently. That meanns we can able to recreate the same once got deleted but from SharePoint 2010 onwards, When you delete a Site from the site settings it is deleted gradually.

Means, if you delete a site, and then create the site with the same name, SharePoint will ask you if you wish to permanently delete the site from the recycle bin so that you can re-create the site

How to restore the deleted site collection in SharePoint?

In prior versions of SharePoint Server 2010, if a site collection (that is, an SPSite object) was accidentally deleted, there was not a direct way of restoring a specific deleted site collection. The only method to restore a deleted site collection was to restore the entire farm from a backup. This was costly and time consuming, and typically was not performed.

When a site collection is accidentally deleted in SharePoint Server 2010 with SP1, the deleted site collection is stored in the SPDeletedSite object, not the SPSite object. Therefore, to restore a deleted site collection, you must use the Restore-SPDeletedSite Windows PowerShell cmdlet or programmatically access the object model.

E.g.:  Get-SPDeletedSite -Identity /sites/sitename | Restore-SPDeletedSite

My SharePoint site has exceeded the mentioned  Quota size limit but users still wants to add new doc to the document library? How can we achieve this?

Shorter way: Delete the unwanted data from the second stage of Recycle Bin.

Longer way: Increase Quota limit to the web application.

Note: Go with the second option only in case of if there is no unwanted data available in Recycle Bin. But keep in mind Release required to change the Quota limit [Why I mentioned “Release” point here we cannot directly change anything until unless get approval from the business users in higher level organizations].

Realtime Scenerio: I created site with 200MB of size and uploaded 200MB size of files to the document library[e.g:  2files and each one is having 100MB of size]. Later on, deleted those documents from the document library. But when I try to upload the 50MB of file again to the document library got the exception and it says: site Quota is FULL.

The reason for the exception is, those deleted 200MB files are still stays in first stage of Recycle Bin. Solution: Delete those from the both first stage/second stage Recycle Bin and then try to upload or increase the site Quota.

Note :2^nd stage of Recyle Bin, overwritten the old data when it exceeds.

What is Recycle Bin in sharepoint?

SharePoint has introduced a new feature called Recycle Bin to keep the deleted items, documents. Speciality of this feature is we can easily restore the accidently deleted items and files from the Reycle Bin. 

Recycle Bin Stages:

SharePoint supports two levels of Recycle bin. The initial or First level Recycle bin comes into picture when the user deletes an item from a list. Once the item is deleted again from the First level of Recycle bin it moves to the second stage of Recycle bin.

1st stage, known as the “end user recycle bin”

2nd stage, known as the “deleted from end user recycle bin”.

2nd stage Recycle Bin has a setting of site quotas for space limitations. If it reaches its quota limit, older items will be overwritten. If you are not enabled site quotas then 2nd stage recycle bin will have no space limitations.

Use the 2^nd Stage Recycle Bin to define how long deleted items will stay in the site collection's Recycle Bin that only the administrator can use (Default: 50 percent of the disk quota for the web application. For example, if you have allotted 1000 MB of space for the web application, SharePoint will add 50 percent more (i.e., 500 MB) to that quota (a total quota of 1500 MB) to be used for the second-level Recycle Bin. When this limit is exceeded, the oldest items will be removed from the second stage Recycle Bin.

Note: First stage of Recycle Bin available at site level and only one Second Stage Recycle Bin available per Site Collection.

Below IMP points should keep in mind ever:

1. The Site Recycle Bin feature is newly introduced in Service Pack 1 from SharePoint 2010, if you haven't installed Service Pack 1 for your SharePoint 2010 when you deleted the site collection; you need to restore the content database.
2. The Recycle Bins can contain multiple copies of a document that each have the same file name and source. These documents cannot be restored over an existing copy of a document.
3. The Recycle Bins cannot be used to recover previous versions or accidental overwrites of documents.
4. Turning off the Recycle Bin for a Web application empties all Recycle Bins and permanently deletes all items in them and can only be restore from a backup.
5.  If you have not enabled site quotas, the 2^nd stage recycle bin will have no space limitations.

Who can view the 1^st stage recycle Bin?

Minimum Permssions levels: Contribute, Design, or Full Control Permissions and site collection administrator.

What are all the minimal permissions required to restore the deleted items?

The deleted items can only view of their own and site collection administrator.

Recycle bin access permissions: Contribute , Design, and Full Control permissions.

What are all the permissions required to restore the deleted objects from the second stage of Recycle Bin?

Only the Site Administrator can restore objects from the site collection Recycle Bin.

You should have minimum site collection administrator permissions to restore the other’s deleted data from the Recycle Bin. Means the users who have deleted the content will be able to see the content in the recycle bin and next site collection administrators can view other’s data.

How many days the deleted content will be available in Recycle Bin?

The deleted object will stay in the Recycle Bin for 30 days by default.

After 30 days, the object is moved from the site's Recycle Bin to a site collection Recycle Bin.

All together is 30days: If deletes the item from the first stage recycle bin after 10 days. It moves to second stage recyle bin and stays there another remanining 20days. 

Which timer job cleans the recycle bin data if exceeded the time?

The “Recycle Bin” Timer job and it by default scheduled on daily basis in MOSS2007 and from 2010 onwards scheduled on weekly basis.

How to delete an item permanently from the SharePoint list?

Recycle () method: used for to move the items to the Recycle Bin

Delete () methods: used for to delete the items permanently.
