What are the different types of backups for SharePoint?

1) Incremental Backup2) Full Backup

though it's easy to enable one of these back-ups but ideally you have to be familiar with the script used for backup and restore through powersheel windows and far better understanding of DB of sharepoint.....

I think question is related to the type of backup not level of backup.... :)

We can perform different levels of backup inside SharePoint 2010. The levels include:

• Farm Backup
• Site Collection Backup
• Site Backup
• Web Application Backup
• List Backup
• Library Backup
• Solution Package Backup
• Configuration Backup
• Content Database Backup

Full Farm Backs up and Differential Backs up

Backup from Powershell command, Farm Backup from GUI, And database backup

The types of Backup are:

1. Full Backup
2. Differential Backup
3. Incremental Backup

• Farm   The farm is the highest-level object. You can select from the following options when you perform a farm backup:

  • Content and configuration data (default)

    The whole server farm is backed up. This includes settings from the configuration database.

  • Configuration-only

    Configuration database settings are backed up so that you can apply configurations across farms. For more information, see Configuration-only backup use and benefits later in this article.

• Web application   Within a web application, you can select one or more of the content databases to back up.

  A web application backup includes the following:

  • Application pool name and application pool account

  • Authentication settings

  • General web application settings such as alerts and managed paths

  • Internet Information Services (IIS) binding information, such as the protocol type, host header and port number

  • Changes to the Web.config file that were made through the object model or Central Administration
