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.
The remainder of this section will identify when additional features are made available
through Windows PowerShell commands that are not available through the standard
user interface.

Granular Backup and Restore
SharePoint Server 2010 provides several new features that provide a granular level of
backup for various components of site content. This includes content at the site, subsite,
and list level. This level of granular backup provides SharePoint administrators with the
ability to quickly and flexibly backup and restore content to meet user demand.
Back Up a Site Collection
Backing up a site collection will include the top level site and all subsites. When backing
up the site collection through Central Administration, a SharePoint administrator
identifies the site collection and provides a destination for the storage of the backup file.
