SharePoint backup requirements and considerations

Unitrends protects the following SharePoint environments:

Farm deployments where the SharePoint installation type is full farm (all SharePoint releases) or single server farm (SharePoint 2016). In farm deployments, the SharePoint data and components may reside on one server or on multiple servers. For details, see these Microsoft articles: Install SharePoint Server 2016 across multiple servers, Install SharePoint 2013 across multiple servers for a three-tier farm, or Install SharePoint 2016 on a single server with SQL Server.
Single server deployments where the SharePoint installation type is single server (SharePoint 2010 and 2013). In single server deployments, all SharePoint data and components reside on one server. For details, see this Microsoft article: Install SharePoint 2013 on a single server with SQL Server.

For all installations, the Primary SharePoint server runs the Central Administration website service, which can be accessed using http://<machine name>:<admin port>

The Unitrends Windows agent provides protection of services and resources in a Microsoft standalone or multi-server SharePoint farm.

In a SharePoint deployment, the primary node installs SharePoint services on other member servers and initiates administrative commands to manage the farm. The Central Administration service runs on the primary node to perform farm management. All nodes directly access the SharePoint central configuration database for configuration of services, features, database connections, and the like. The central configuration database resides either on the primary node or on a stand-alone SQL server. Unitrends protects the farm from the primary node, where administrative commands are run to coordinate the backup of data across other nodes in the farm.

To ensure application consistency, the agent leverages SharePoint’s STSADM and PowerShell (SharePoint 2013 and higher) tools to run backup and recovery jobs . The agent invokes commands on the SharePoint primary node and supplies STSADM or PowerShell with a local share target (/backups/rae/<client_name>/<instance>) so that jobs run on the backup appliance itself.

The agent works with STSADM or PowerShell to back up the SharePoint-specific data and files on each node in the farm. STSADM or PowerShell discovers the online nodes and performs backup operations to the local backup appliance share. If a node is not available, the backup continues without error. The resulting backup does not include any nodes that were unavailable when the backup ran.

Notes:   

SharePoint protection includes SharePoint data only. To protect an entire node in the farm, add the node to the backup appliance and run file-level backups.
Full catastrophic farm recovery can only be performed for SharePoint 2013 and 2010 deployments where the installation type is single server. For full farm (all SharePoint releases) or single server farm (SharePoint 2016) installations, you must recover items instead. To check your installation type, see To determine the installation type for SharePoint 2013 and 2010 deployments.

Consider the following before implementing your SharePoint protection strategy:
