Snapmirror data replication

Protect your data and ensure its availability

Natural disasters, hardware failure, and site outages can leave your business reeling. SnapMirror data replication is built-in data protection technology for NetApp ONTAP clusters, It replicates your data across on-premises and cloud environments, helping you prepare for disasters and meet recovery point objective (RPO) and recovery time objective (RTO). Now available for NAS.

How do you keep data available when a disaster strikes?

Business disruptions shouldn’t mean business downtime. NetApp SnapMirror keeps your data synchronized across systems for SAN and now available for NAS, helping ensure critical applications including Microsoft Exchange, Microsoft SQL Server and Oracle remain available and recoverable during cyber incidents, infrastructure failures or planned maintenance.

When you replicate data to one or more NetApp storage systems and continually update the secondary data, your data is kept current and remains available when you need it. No external replication servers are required.

If our systems go down, small businesses across Europe can’t sell, communicate, or operate. It’s that simple. Reliability isn’t something we talk about — it’s something our customers live by.

FAQS

SnapMirror data replication is data protection technology built into every NetApp ONTAP cluster. It offers scalability, flexibility, and rapid recovery for mission-critical, data-dependent applications by creating replicas of your data and enabling recovery in the event of a primary data storage failure.

Every minute your data is unavailable means lost opportunity. When primary data access fails, you need to restore access as quickly as possible. SnapMirror data replication empowers businesses to do exactly that, with configurable RPOs down to minutes, and near-zero RPO available with SnapMirror Synchronous.

SnapMirror protects all your ONTAP data by replicating it with native ONTAP storage efficiencies in place. It can also replicate NAS data access information and access controls. SnapMirror is designed to meet you where your data resides, whether on-premises or in the cloud, so when you need to recover from a primary data access failure, recovery is as close as a click of a button.

SnapMirror Asynchronous replicates data on a schedule you define, with RPOs down to minutes, making it well-suited for organizations that need flexible, cost-efficient protection. SnapMirror Synchronous writes data to both sites simultaneously for near-zero RPO, making it better suited for workloads where even minimal data loss is unacceptable, such as financial transactions or critical databases.

No. When you replicate data to one or more NetApp storage systems and continually update the secondary data, your data stays current and remains available, with no external replication servers required.
