SnapCenter overview
SnapCenter Software is a simple, centralized, scalable platform that provides application-consistent data protection for applications, databases, host file systems, and VMs running on ONTAP systems anywhere in the Hybrid Cloud.
SnapCenter leverages NetApp Snapshot, SnapRestore, FlexClone, SnapMirror, and SnapVault technologies to provide the following:
-
Fast, space-efficient, application-consistent, disk-based backups
-
Rapid, granular restore, and application-consistent recovery
-
Quick, space-efficient cloning
SnapCenter includes both SnapCenter Server and individual lightweight plug-ins. You can automate deployment of plug-ins to remote application hosts, schedule backup, verification, and clone operations, and monitor all data protection operations.
SnapCenter can be deployed in the following ways:
-
On premise to protect the following:
-
Data that is on ONTAP FAS or AFF primary systems and replicated to ONTAP FAS or AFF secondary systems
-
Data that is on ONTAP Select primary systems
-
-
On premise in a Hybrid Cloud to protect the following:
-
Data that is on ONTAP FAS or AFF primary systems and replicated to Cloud Volumes ONTAP or NetApp Private Storage secondary systems
-
-
In a public cloud to protect the following:
-
Data that is on Cloud Volumes ONTAP (formerly ONTAP Cloud) primary systems
-
SnapCenter includes the following key features:
-
Centralized, application-consistent data protection
Data protection is supported for Microsoft Exchange Server, Microsoft SQL Server, Oracle Databases on Linux or AIX, SAP HANA database, and Windows Host Filesystems running on ONTAP systems.
Data protection is also supported for other standard or custom applications and databases by providing a framework to create user-defined SnapCenter plug-ins. This enables data protection for other applications and databases from the same single-pane-of-glass. By leveraging this framework, NetApp has released SnapCenter custom plug-ins for IBM DB2, MongoDB, and MySQL.
-
Policy-based backups
Policy-based backups leverage NetApp Snapshot copy technology to create fast, space-efficient, application-consistent, disk-based backups. Optionally, you can automate protection of these backups to secondary storage by updates to existing protection relationships.
-
Back ups for multiple resources
You can back up multiple resources (applications, databases, or host file systems) of the same type, at the same time, by using SnapCenter resource groups.
-
Restore and recovery
SnapCenter provides rapid, granular restores of backups and application-consistent, time-based recovery. You can restore from any destination in the Hybrid Cloud.
-
Cloning
SnapCenter provides quick, space-efficient, application-consistent cloning, which enables accelerated software development. You can clone on any destination in the Hybrid Cloud.
-
Single user management graphical user interface (GUI)
The SnapCenter GUI provides a single, one-stop interface for managing backups and clones of a resource in any destination in the Hybrid Cloud.
-
REST APIs, Windows cmdlets, UNIX commands
SnapCenter includes REST APIs for most functionality for integration with any orchestration software, and use of Windows PowerShell cmdlets and command-line interface.
For more information on REST APIs see REST API overview.
For more information on Windows cmdlets see SnapCenter Software Cmdlet Reference Guide.
For more information on UNIX commands see SnapCenter Software Command Reference Guide.
-
Centralized data protection Dashboard and reporting
-
Role-Based Access Control (RBAC) for security and delegation.
-
Repository database with High Availability
SnapCenter provides a built-in repository database with High Availability to store all backup metadata.
-
Automated push install of plug-ins
You can automate a remote push of SnapCenter plug-ins from the SnapCenter Server host to application hosts.
-
High Availability
High availability for SnapCenter is set up using external load balancer (F5). Up to two nodes are supported within the same datacenter.
-
Disaster Recovery (DR)
You can recover the SnapCenter Server in the event of disasters like resource corruption or server crash.
SnapCenter architecture
The SnapCenter platform is based on a multitiered architecture that includes a centralized management server (SnapCenter Server) and a SnapCenter plug-in host.
SnapCenter supports multisite data center. The SnapCenter Server and the plug-in host can be at different geographical locations.
SnapCenter components
SnapCenter consists of the SnapCenter Server and SnapCenter plug-ins. You should install only the plug-ins that are appropriate for the data you want to protect.
-
SnapCenter Server
-
SnapCenter Plug-ins Package for Windows, which includes the following plug-ins:
-
SnapCenter Plug-in for Microsoft SQL Server
-
SnapCenter Plug-in for Microsoft Windows
-
SnapCenter Plug-in for Microsoft Exchange Server
-
SnapCenter Plug-in for SAP HANA Database
-
-
SnapCenter Plug-ins Package for Linux, which includes the following plug-ins:
-
SnapCenter Plug-in for Oracle Database
-
SnapCenter Plug-in for SAP HANA Database
-
SnapCenter Plug-in for UNIX
SnapCenter Plug-in for UNIX is not a standalone plug-in and cannot be installed independently. This plug-in is automatically installed when you install either SnapCenter Plug-in for Oracle Database or SnapCenter Plug-in for SAP HANA Database.
-
-
SnapCenter Plug-ins Package for AIX, which includes the following plug-ins:
-
SnapCenter Plug-in for Oracle Database
-
SnapCenter Plug-in for UNIX
SnapCenter Plug-in for UNIX is not a standalone plug-in and cannot be installed independently. This plug-in is automatically installed when you install SnapCenter Plug-in for Oracle Database.
-
-
SnapCenter Custom Plug-ins
Custom plug-ins are community-supported.
SnapCenter Plug-in for VMware vSphere, formerly NetApp Data Broker, is a standalone virtual appliance that supports SnapCenter data protection operations on virtualized databases and file systems.
SnapCenter server
The SnapCenter Server includes a web server, a centralized HTML5-based user interface, PowerShell cmdlets, REST APIs, and the SnapCenter repository.
SnapCenter enables high availability and horizontal scaling across multiple SnapCenter Servers within a single user interface. You can accomplish high availability by using external load balancer (F5). For larger environments with thousands of hosts, adding multiple SnapCenter Servers can help balance the load.
-
If you are using the SnapCenter Plug-ins Package for Windows, the host agent runs on the SnapCenter Server and Windows plug-in host. The host agent executes the schedules natively on the remote Windows host, or for Microsoft SQL Servers, the schedule is executed on the local SQL instance.
The SnapCenter Server communicates with the Windows plug-ins through the host agent.
-
If you are using the SnapCenter Plug-ins Package for Linux or the SnapCenter Plug-ins Package for AIX, schedules are executed on the SnapCenter Server as Windows task schedules.
-
For SnapCenter Plug-in for Oracle Database, the host agent that runs on the SnapCenter Server host communicates with the SnapCenter Plug-in Loader (SPL) that runs on the Linux or AIX host to perform different data protection operations.
-
For SnapCenter Plug-in for SAP HANA Database and SnapCenter Custom Plug-ins, the SnapCenter Server communicates with these plug-ins through the SCCore agent that runs on the host.
-
The SnapCenter Server and plug-ins communicate with the host agent using HTTPS.
Information about SnapCenter operations is stored in the SnapCenter repository.
