Disaster Recovery


Business resilience is the ability to recover from adverse events such as natural disasters, technological failures, human error, or intentional harm. Enterprises must restore operations as quickly as possible, regain momentum, and recover as much information as possible. In short, disaster recovery is about reducing the return to operations and mitigating data loss.

These goals require a viable business continuity plan. But no plan is static. New business practices, changes in technology, and escalating concerns about vulnerability have focused even greater attention on the need for effective business continuity planning and have altered the benchmarks of an effective plan.

Building a Better Business Continuity Plan:

  1. Consider potential site loss and area-wide disasters that impact an entire region and the resulting inaccessibility of staff.
  2. Address interdependencies, both market-based and geographic, among your business eco-system participants as well as infrastructure service providers.
  3. Establish recovery time objectives and redundancy acceptance levels for each application and required system.
  4. Accommodate mixed environments, where a variety of databases are present. Disaster recovery software and high availability solutions must be heterogeneous to be complete and effective.
  5. Evaluate OLTP systems versus batch systems protection and recovery requirements for each.

To meet the objectives of your enterprise Business Continuity Plan, consider the pyramid of availability and recovery solutions, balancing the benefits of complete redundancy with the costs of implementation and maintenance. All applications are not created equal: Some may not require the same protection as mission-critical systems.

From complete redundancy at the top of the pyramid to straight-forward transactional replication, Sybase has a solution. Let us create a customized Business Continuity Plan for your business. Your data and your business will be protected – and you’ll sleep better.

Adaptive Server Enterprise (ASE) HA Option – provides near continuous database access by leveraging cluster architecture – creating ASE “companion” databases. Client connections and database operations can instantly move from one server to the other without interrupting end-users.

Replication Server – allows DBAs to quickly setup redundant disaster recovery and rapid failover sites and to ensure the transactional integrity of all replicated information.

Mirror Activator – ensures zero data loss, dramatically lowers time to recovery and activates secondary site systems. It leverages storage replication systems including EMC SRDF, IBM PPRC, Hitachi TrueCopy, Veritas Volume Replicator and Network Appliance SnapMirror.

Open Switch – seamlessly routes end-users from the primary system to a back-up system when an outage is detected. During planned downtime, a simple flip of a software switch transfers client connections to backup servers.
