Site-to-site VPN connection

Enable secure VPN connection between the client’s local site and the cloud site to facilitate partial failover of tightly dependent servers on the local site. When one of the servers is recreated on the cloud site, the servers continue to communicate, ensuring minimal downtime.

Test DR readiness

Perform DR testing in an isolated environment to confirm application availability, ensure compliance, and prove DR readiness — without any impact on production systems.

Execution monitoring

Gain visibility into disaster recovery orchestration with a detailed runbook-execution real-time view and execution history.

Point-in-time recovery

Prevent data loss and avoid data corruption with granularity of control over data protection and recovery capabilities. Restore systems and data to any recoverable point in the past, instead of to the latest one.

IPsec multisite VPN support

What is disaster recovery solution ?

Disaster recovery solutions allow companies to quickly resume business-critical workloads after cyber-attacks, natural disasters or server failures. The disaster recovery process normally involves a separate physical or cloud site to restore data. Every disaster recovery solution aims to help businesses operate as usual. Since business continuity depends on high availability, disaster recovery strategies depend on RTOs and RPOs.

What’s the difference between backup and disaster recovery solutions?

Backups are simple; they are copy of your corporate systems and data that can be used to bring a failed system back online. Disaster recovery refers to a more advanced form of system copies that include processing capabilities.

Where should I back up my data to perform disaster recovery?

To be able to failover your critical workloads, you should back up your data to to our Cloud Storage (or, cold storage for backups). As the disaster occurs, your workload will be failed-over to the off-site server running in the CAL Disaster Recovery Storage (or, hot storage in the Cloud).

What goes into a disaster recovery plan?

Your business has its own unique data requirements, so a good plan will minimize the complexity of the disaster recovery process. To define the correct approach to creating a disaster recovery plan for your business, you will need to assess the applications, process, and cost versus risk.

What data should I back up for effective disaster recovery?

For reliable disaster recovery, you need to look beyond simply copying all of your databases and files. Your entire infrastructure – servers, PCs, NAS, SAN, hypervisors, and endpoints – contains vital production data. You’ll need to capture application settings, operating system configurations, bookmarks, and registry data for a full recovery.

What’s the difference between RPO and RTO ?

A Recovery Point Objective (RPO) is the point in time that data, systems, and applications will be recovered to. A Recovery Time Objective (RTO) is how much time can pass before your business must be restored.

What is the best method for disaster recovery ?

There are three different ways you can store business-critical data: local data center, in the cloud, or you can take a hybrid approach.


With a data center, your critical data is stored off-site in a physical location, but disaster recovery can take days or weeks. Although this is considered the most secure storage option, it is also the most expensive as facilities, and additional systems and staff are required.


Cloud disaster recovery is the most cost-effective and scalable option. With this option, you leverage a cloud data center to store your critical systems (whether physical or virtual), data, and applications. Cloud disaster recovery allows you to keep entire virtual environments at the ready, reducing recovery from a disaster or business outage to minutes or even seconds.


A hybrid cloud disaster recovery method uses a public cloud and private data center (physical or cloud). This provides a great degree of flexibility, keeps costs down, while also meeting any regulatory and compliance needs.


With all three methods, be sure to evaluate the pros and cons of each against your individual business requirements.

Can I access CAL Disaster Recovery infrastructure globally?

You can access the CAL management console everywhere the internet connection is available. The CAL Disaster Recovery add-on is available globally .

Should I test my disaster recovery plan?

The success of your disaster recovery plan depends on preparedness of people and processes as much as the backup tools used. Ideally, you should test your disaster recovery procedures every 3 months (but no less than once a year). Do not forget to amend and extend your disaster recovery plan during and after these exercises.

I'm a customer with on-premises installation, how can I get CAL Disaster Recovery?

To start using CAL Disaster Recovery Add-on, you will need to have CAL subscription license to access the management console in the CAL cloud. This new cloud installation will allow you to protect new systems so you will need to configure settings accordingly (i.e. the system will not include your previous on-premises backup configurations.)
