Once a Backup exists, users can create updates by capturing a full or incremental snapshots of their SharePoint environment. Here are the basic guidelines for this process:
1.Select an existing Backup project from the Backup Navigator panel.
2.From the Ribbon (or right-click menu for the selected backup) select the Update Backup option. This will generate the Update Backup Properties screen.
3.A user may select one of several options for the update:
Full Update - this will create a full snapshot of your currently configured backup project.
Incremental Backup - this will capture only the changes in your backup project since the last update, regardless if that update was Full or Incremental. In this scenario a user could create a series of Backups containing data changes for a specific time period.
Differential Backup - this will capture all the changes in your backup project since the last full Backup, even if other incremental Backups have been created in the interim.
4.Press Finish to update the Backup now or choose the Schedule button to configure a Windows Task Scheduler task to schedule the update backup (See the Scheduling Backup Jobs section for more information).
