Zert0 – SQL Server Replication & Recovery

SQL Server, database replication, and remote backup.

Microsoft SQL Server is a robust database application that is used by hundreds of thousands of organizations around the world. A crash or logical failure affecting the availability of Microsoft SQL Server can result in data loss, significantly reducing employee productivity and even damaging the company’s brand and impacting stock prices, making BC/DR extremely important to organizations of all sizes.

Microsoft SQL Server Security Issues

Securing Microsoft SQL databases is challenging because transactions are recorded quickly and continuously, with a high change rate. Many organizations use log transport, application-based or storage-based replication, as protection technologies for BC/DR, which lead to complex and manual recovery processes and require specialized knowledge, which increases the degree of risk. In addition to this complexity, the problem may be simply retrieving data from the recovery site. If the data is not compressed, then it can overload the network, if the write order is not supported, the database will be in an unstable state, and many protection technologies will not allow you to correctly assess the state of protection and management of SLAs.

In addition, Microsoft SQL Databases is typically part of an enterprise multi-VM application that includes multiple virtual machines with potential terabytes of data associated with it, which hardly guarantees that the entire application can be recovered. If a group of virtual machines cannot be restored at the same point in time, a lengthy manual restore will be required, which will affect the state of the business in the future.

Benefits of Securing Microsoft SQL Server with Zerto Virtual Replication

By simply selecting the virtual machines (VMs) that host microsoft SQL Server that are protected, Zerto Virtual Replication provides a robust, enterprise-class BC/DR solution that provides instant Recovery Point Objectives (RPOs) and minute Recovery Time Objectives (RTOs), with advanced features for maintaining high-transactional database protection. To protect Microsoft SQL servers, Zerto Virtual Replication does not require complex application integration, since all replications are performed in a hypervisor, which makes the solution simple and scalable, which has the following characteristics:

  • The hypervisor is integrated with simple centralized management with clear visibility into the state of the protection system, key performance indicators and SLAs
  • You do not need to change SQL configurations to configure protection
  • RPOs in seconds, no snapshots, and no performance impact
  • The recovery point increases every few seconds, up to 14 days ago, maintaining the validity of the write order in all SQL Database records, eliminating the need for log delivery.
  • No KNOWLEDGE of SQL is required to recover from failures
  • SQL VSS integrates to distribute successive application points in time
  • Initial TempDB replication, without further modification, saves 50% of replication traffic
  • RTOs in minutes – with load ordering and automatic IP reconfiguration
  • Sequential multi-VM application recovery with Virtual Group Protection (VPG) technology
  • Non-impact testing after failures, without interruption of replication or stoppage of production
    SQL Fault Tolerance Test with Application Servers in Isolated Networks
  • User-initiated fault tolerance eliminates potential false failures
  • Protect physical or virtual Raw Device Mappings (RDMs) on virtual disks or remote diagnostic managers (RDMs) pre-provisioned on the target site

Finally, the ZVR Remote Backup feature takes information replicated for disaster recovery purposes and uses it for backup purposes, which reduces the load on production volumes.

Resume

Many companies rely on Microsoft SQL Server. And if the database isn’t available, productivity and revenues fall and worsen a company’s hard-earned reputation and brand. Zerto Virtual Replication uses block-level continuous replication, which is specifically designed to maintain data integrity in rapidly changing databases while minimizing data loss. Through the automation of fault tolerance, recovery and DR testing, aggressive service levels are implemented with RPOs in seconds and RTOs in minutes, maintaining the integrity of data integrity.
