Application Continuity

XoSoft High Availability Solution Suite
( WAN SYNC and BUSINESS CONTINTUITY )

WANSyncHA is a high availability solution based on asynchronous real-time replication and automatic failover and failback to provide cost-effective business continuity for Microsoft Exchange, Microsoft SQL Server, Oracle, Microsoft IIS webservers, file servers, and other applications on both 32- and 64 bit Windows servers.

WANSyncHA offers automated push-button or fully automatic failover of mission-critical application servers over a LAN or WAN, application-aware status monitoring, integrated continuous data protection as a guard against data corruption, and completely non-disruptive automatic testing of your disaster recovery system, all in a system that sets the standard for ease of configuration and management.

When disaster strikes, whether in the form of a hurricane, a blackout, or far more likely, a virus attack or software or user error, your ability to respond well to the crisis can make the difference between a bright future and the end of your business. At the very least, you are likely to incur significant costs in lost business and, perhaps more importantly, lost confidence by your customers, investors, and other stakeholders. Business continuity is not just about insurance. It is about maintaining your competitive edge.

WANSyncHA, a High Availability Solution for True Business Continuity

WANSyncHA is a high availability business continuity solution that integrates several technologies to provide continuous availability of your mission-critical application servers through a wide range of disruptions from server failure to data corruption to the loss of an entire site.

WANSyncHA provides:

• Asynchronous host-based software replication that transfers changes to application data as they occur to a standby replica server located locally or over the WAN
• Automatic monitoring of your production application, including both server availability and the state of application services and data for supported applications like Exchange, Oracle, and SQL Server
• Push-button or auto-triggered automatic failover of all users to a standby server, which may be on the same network or across a WAN at an arbitrarily distant site
• Push-button or automatic failover back to the original server when ready
• Continuous data protection based on XOsoft's Rewind Technology for recovery from data corrupted by virus action or user or application error
• Tailored support for Microsoft Exchange, SQL Server, Oracle, and file servers, as well as other applications
• Unique ease of installation with no application or user downtime, automated remote installation, and wizard-driven creation of new high availability scenarios
• Assessment mode measures exact change rate during evaluation to aid in estimating bandwidth requirements

In addition, for compliance and testing purposes, XOsoft's Assured Recovery works in conjunction with the WANSyncHA high availability solution to support full testing of the recoverability of your application and data on a disaster recovery replica system.

Disaster Recovery Testing Doesn't Have to be a Disaster

XOsoft's Assured Recovery is a breakthrough technology that makes your disaster recovery investment truly complete by enabling you to conduct comprehensive and regular tests of your disaster recovery standby servers without any disruption to your production servers or any interruption to your disaster recovery protection. Assured Recovery testing solutions can be paired with WANSync or WANSyncHA, and tailored solutions are available for Microsoft Exchange, SQL Server, and IIS web servers, as well as Oracle database servers.

Assured Recovery is not a proprietary testing solution. It is a technology that allows you to perform a real test of your disaster recovery server by actually running the application, even modifying data, without impacting your production environment in any way. In fact, Assured Recovery offers this functionality without ever leaving your production systems vulnerable during testing, without disrupting production application availability in any way, and without the need for expensive data resynchronization after testing is complete.

At the same time, Assured Recovery allows you to perform a backup or snapshot of the validated data directly on your disaster recovery server, a tremendously cost-effective way to obtain offsite or consolidated backups and snapshots of your mission critical application data.

The Assured Recovery solution is unique in providing full disaster recovery testing of your actual servers in your actual environment without any negative impact at all.

An Untested Solution is No Solution

Why is this important?

You've secured your organization's most critical assets by implementing a disaster recovery solution. Although you thoroughly tested and verified this solution during implementation, your environment will have changed over time and may have altered the state of your systems. These include changing server configurations, altered network setups, virus infections and hardware failures. Any gap in time since the last disaster recovery test conducted will amount to a growing gap in assurance that your disaster recovery system will work as planned. What's the only way to close this gap? Regular disaster recovery tests.

To ensure the integrity and effectiveness of your disaster recovery capability in the face of such constant changes, it's not just sensible, but critical to conduct regular disaster recovery tests. In fact, no disaster recovery solution is complete without frequent disaster recovery testing.
