Your Server Crashes Tomorrow Morning: How Long Before Everything's Back Up?
Without a recovery plan, the answer can be measured in days. Azure Site Recovery continuously replicates your virtual machines to a secondary site: the recovery time is defined, tested and measured in advance.

Disaster can strike at any time. A well-designed disaster recovery plan with Azure lets your company restart within a timeframe known in advance.
Azure Site Recovery: continuous replication
ASR replicates your virtual machines to a secondary Azure region. Replication is continuous with an RPO of a few minutes. In case of disaster, failover is just a few clicks away.
Define adapted RTO and RPO
RTO defines how long your business can be interrupted. RPO defines how much data you can lose. These metrics guide architecture. Helion Cloud helps you calibrate.
Failover testing
An untested DRP may fail on the day you need it. Azure Site Recovery allows testing without production impact. Plan regular exercises.
Beyond VMs
Azure Backup protects data. Azure databases offer native replication options. For Microsoft 365, retention policies do not replace a backup: the Microsoft 365 Backup service, billed separately, restores OneDrive, SharePoint and Exchange.
Summary
A DRP is no longer a luxury but a necessity. Helion Cloud designs and deploys Azure disaster recovery solutions adapted to your budget.
