High Availability Manager Beta

Maximize service uptime with automatic failover
Downtime Disrupts More Than Work
Whether you're managing enterprise data, running virtual machines, or hosting mission-critical applications, downtime is your enemy. Just a few minutes of system failure can lead to:
Disrupted operations
Lost revenue
Damaged reputation
Expensive recovery efforts
And traditional backup solutions?
They often fall short when you need real-time failover.
Automatic Failover for Peace of Mind
QNAP's revamped High Availability Manager now supports Active-Passive HA architecture, designed to keep your business online at all times.
Two QNAP NAS devices are configured in a HA cluster: one active, one passive. The passive NAS continuously mirrors the active one. If the active fails, the passive automatically takes over within minutes.

Hospitals storing patient records and imaging data can’t afford downtime. QNAP’s HA protects sensitive data and ensures systems remain online during maintenance or outages.
