SnapCenter Software 5 Manuals ( CA08871-403 )

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 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 ETERNUS AX/AC/HX series primary systems and replicated to ETERNUS AX/AC/HX series secondary systems
- Data that is on ETERNUS AX/AC/HX series primary and secondary systems and protected to local StorageGRID object storage
On premise in a Hybrid Cloud to protect the following:
- Data that is on ETERNUS AX/AC/HX series primary systems and replicated to Cloud Volumes ONTAP
- Data that is on ETERNUS AX/AC/HX series primary and secondary systems and protected to object and archive storage in cloud (using BlueXP backup and recovery integration)
In a public cloud to protect the following:
- Data that is on Cloud Volumes ONTAP primary systems
- Data that is on Amazon FSX for ONTAP

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.
Policy-based backups

Policy-based backups leverage 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 See REST API overview.
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.
SnapLock

SnapLock is a high-performance compliance solution for organizations that use write once, read many (WORM) storage to retain files in unmodified form for regulatory and governance purposes.

For more information on SnapLock refer What SnapLock is
SnapMirror Business Continuity (SM-BC)

SnapMirror Business Continuity (SM-BC) enables business services to continue operating even through a complete site failure, supporting applications to fail over transparently using a secondary copy. Neither manual intervention nor additional scripting is required to trigger a failover with SM-BC.

The plug-ins supported for this feature are SnapCenter Plug-in for SQL Server, SnapCenter Plug-in for Windows, and SnapCenter Plug-in for Oracle database.

For more information on SM-BC refer SnapMirror Business Continuity (SM-BC)

For SM-BC, ensure that you have met the various hardware, software, and system configuration requirements. For more information refer Prerequisites
Synchronous mirroring

The Synchronous mirroring feature provides online, real-time data replication between storage arrays over a remote distance.

For more information on Sync mirror refer Synchronous mirroring overview

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 file systems
SnapCenter Plug-ins Package for AIX, which includes the following plug-ins:
- SnapCenter Plug-in for Oracle Database
- SnapCenter Plug-in for UNIX file systems
SnapCenter Custom Plug-ins

SnapCenter Plug-in for VMware vSphere, 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.

SnapCenter supports disjoint namespace for Windows hosts.
