Disaster Recovery / DRaaS

Native Disaster Recovery in HC3®

HC3 replication, snapshot, and cloning technologies combine to provide a full set of backup and recovery capabilities to make sure you data is always protected. Scheduling, retention, recovery, failover, failback, and DR testing are all part of HC3 at no additional cost.

Continuous Per-VM Replication:

HC3 makes use of its space efficient snapshot technology to replicate to a secondary site, tracking and sending only the changed blocks.

Low RPO/RTO and Flexible Scheduling:

Continuously replicate as often as every 5 minutes and failover within minutes while tailoring replication schedules per VM.

Simple Disaster Recovery Testing:

Testing a DR infrastructure plan is now as simple as cloning a snapshot on the target cluster and starting a VM. No disruption to ongoing replication.

Easy Failback after Disaster Recovery:

After running a VM at the DR site, simply replicate the changed data back to the primary site for simple failback.

HC3® Cloud Unity DRaaS

For organizations that either lack a remote site for disaster recovery or would simply prefer not to deploy their own disaster recovery site, Scale Computing offers HC3 Cloud Unity DRaaS. This disaster recovery as a service offering provides an HC3 DR target running securely in Google Cloud Platform. Workloads can be replicated to the Google cloud for failover or recovery on a per VM basis. Your HC3 on-prem system is already acting as a private cloud so cloud-based disaster recovery fits perfectly.

As a service, this option allows predictable pricing that can protect anywhere from a single VM to any number of VMs on HC3 clusters. This service uses the built-in snapshot and replication features that can provide RPO and RTO measured in minutes. There is no VPN required for connectivity. HC3 Cloud Unity DRaaS uses L2 networking to provide seamless connectivity between on-prem and remote hosted VMs in the event of failover.

HC3 Cloud Unity DRaaS includes award-winning ScaleCare support at every stage to assist in setup, testing, failover, and recovery. The service also comes with a runbook to assist with both planning and execution. When needed, all protected VMs can be failed over and running in the cloud and then failed back once the on-prem resources are restored.

Whether an organization does not have a second site or would rather not manage one, DRaaS is a perfect fit. The combination of predictable cost and reliable recovery will provide piece of mind for business continuity. Click here for more information on HC3 Cloud Unity DRaaS.

HC3® Availability Powered by Double-Take® Making use of Existing Infrastructure

HC3 Availability powered by Double-Take allows users to make use of their existing infrastructure by providing a failover of VMs between an HC3 cluster and an existing VMware or HyperV environment. Implement HC3 at your primary site and move your existing infrastructure to a secondary site for Disaster Recovery using HC3 Availability.

HC3 Availability provides affordable data protection, fault tolerance and enables immediate recovery from any system outage at the push of a button. Continuous data replication over any distance means that you always have access to a current copy of your data, applications and operating system (OS).

Platforms Supported

x86 or x64 Windows & Linux Servers
Windows Server 2003 R1/R2, 2008 R1/R2, 2012 R1R2
Red Hat Enterprise Linux/CentOS
Oracle Enterprise Linux 5 and 6
SUSE Linux Enterprise 10 and 11
Ubuntu 10.04 and 12.04 LTS

Continuous, Asynchronous Byte-Level Replication Over Any Distance:

C3 Availability powered by Double-Take monitors changes to all protected files or virtual machines and replicates only the bytes that change to a remote disaster recovery site, over standard IP networks.

Application Awareness for Reliable Recovery:

Application-specific technology in HC3 Availability powered by Double-Take constantly monitors the behavior of applications and databases like Exchange, SharePoint, and SQL, and automatically takes corrective action based on an application’s behavior.

Flexible Bandwidth Scheduling:

Impose higher or lower network usage limits during those times when most appropriate for your business. Limit network use of HC3 Availability powered by Double-Take during busy work hours and increase or remove these limits during non-peak times for efficient replication with the least amount of impact on production resources.

Protects Exchange, SQL Server, Share Point and More:

HC3 Availability powered by Double-Take is hardware and application independent, allowing you to use the hardware and software that suit your business.

Point-In-Time Recovery:

HC3 Availability powered by Double-Take integrates with Microsoft Volume Shadow Copy Service to allow you to schedule and recover from up to 64 point-in-time copies of data on your HC3 Availability powered by Double-Take target when running on an HC3 VM.
