# Offline Mining for SharePoint Server

You can browse and restore granular data, such as a file, a library, a sub site, or a site collection. Offline mining of data is useful when granular backup is not available.

## Server Requirements

- To perform a granular restore, you must have a content database attached to a SQL server.

- Verify that you are performing offline mining on one of the following versions of SharePoint server:

  - SharePoint Server 2019

  - SharePoint Server 2016

  - SharePoint Sever 2013

Important

Offline mining is not supported for SharePoint Server Subscription Edition (SE).

In SharePoint SE, Microsoft removed the API required by Commvault to read database contents during the offline mining process (Microsoft.SharePoint.dll). As a result, offline mining operations will fail in this version.

If you are using SharePoint Server Subscription Edition:

- Do not attempt offline mining with Commvault.

- Use the native SharePoint Central Administration console to access data from the offline-restored database.

- Perform the required restore operations using SharePoint-native tools.

For detailed steps, contact your SharePoint Administrator.

## Client Requirements

- The source client machine must have a SQL server with a content database attached. You can attach a content database to the source client machine using any of the following methods:

  - Cloning a SQL Database

  - Performing a SQL Database In-Place Restore Operation

  - Performing a SQL Database Out-of-Place Restore Operation

  - Performing a SQL Database Restore to Disk Operation

- The SharePoint agent must be installed on a SharePoint application server.
