Ans. Microsoft SharePoint Server 2010 provides a broad range of levels for performing backups, including the entire farm, farm configuration information, site collections, subsites, or lists.
SharePoint Server 2010 uses two different tools to configure backup and recovery.
1. Central Administration : Central Administration provides a user interface where SharePoint Administrators will be prompted via menu structures to select the information that needs to be backed up. (see the Image below)
2. Windows PowerShell : Windows PowerShell is a command line tool that provides SharePoint administrators a way to perform backup and recovery with additional options such as file compression or working with SQL snapshots.
Listed below are a few of the benefits available when working with Windows PowerShell:
. Windows PowerShell scripts can be developed and scheduled (with Windows Task Scheduler), whereas Central Administration is used for single-use backups and restores.
. Windows PowerShell has the advantage of running against SQL snapshots instead of the production database. One of the parameters of the Windows PowerShell command will cause a SQL snapshot to be generated, and then Windows PowerShell will run the action against the snapshot instead of the production database. This will reduce the resource impact of the backup operation on the production environment.
. With Windows PowerShell, SharePoint administrators will have more granular control of options for the backup or restore.
