Explanation:
You can back up a site collection in SharePoint Server by using the SharePoint Central Administration website or Microsoft PowerShell. In this scenario Windows PowerShell is preferred.
Before you begin this operation, review the following information:
* You must first create a folder on the local computer or the network in which to store the backups. For better performance, we recommend that you back up to the local computer and then move the backup files to a network folder.
* If the site collection's Lock status is set to Not locked or Adding content prevented, SharePoint Server temporarily sets the site to Read-Only while the backup operation is occurring. SharePoint Server does this to reduce the possibilities of users changing the site collection while it is being backed up. After the backup is complete, the setting is changed back its normal status.
* Performing a site collection backup might require resources and might slightly affect farm performance when the backup is running. You can help avoid performance issues by backing up the farm during hours when farm use is lowest, such as outside office hours.
Scenario: Backup and Recovery
* In the event of hardware failure, the SharePoint environment must be restored to the most recent date.
* The backup process must not degrade system performance.
* Automation: Windows PowerShell must be used to automate all operations wherever possible.
