Double-Take 7.1 gives to our clients flexible opportunities for expansion of infrastructure of data warehouses in the future. It means that clients can easily and quickly select several resources for storage of the data – any of physical servers, Hyper-V virtual machines or the Azure cloud environment offered by us. Thanks to Vision Solutions they can surely and expedite migration of the data, without caring for their security".

According to industry reports, many companies pass to use of data warehouses which are placed in cloud environments, within implementation of strategy of expansion of a field of activity and cost reduction. Thanks to a possibility of accounting of an expense suppliers of managed services can use the solution Double-Take DR consistently to provide DRaaS (disaster recovery as service) to the clients with functions of drawing up reports on use and managements of licenses.

Representatives of the company integrator reported TAdviser.

Double-Take Availability 6

Using permanent replication in real time the function of data recovery implemented in the product Double-Take from a temporary point allows to exercise setup and control of the schedule shadow copy service (VSS) on platforms Microsoft Hyper-V and VMware. The special pre-installed virtual application automates installation and setup of a system of ensuring data availability. For systems virtualizations Hyper-V using Clustered Shared Volumes technologies the fault tolerance and system recovery is provided with 'one click' that allows to move virtual machines between physical servers. Management of scenarios via the Double-Take single console protects key applications, such Microsoft Exchange as well as SQL Server and also virtualization platforms of VMware and Hyper-V. Support of the PowerShell tool of the company Microsoft. allows to manage tasks and to automate them using its scripting language.

Double-Take Availability 5.3

Allows to configure replication of the virtual machine (VM) at the level of a host (server), exempting from need of preliminary installation of the program replication agent (this agent is established on each VM after completion of setup of replication). Also in the new version the remote clustering of the virtual servers Microsoft Hyper-V, ensuring high readiness of the mail Microsoft Exchange 2010 systems using the Data Availability Group (DAG) mechanism, the accelerated recovery of a configuration of the server and VM unrolled on it and the single console of management are implemented.

Key advantages of the program:

• Continuous replication of data through any distances will always allow you to have access to the complete copy of your data, applications and the operating system to within the last second.
• Monitors changes in all protected files and duplicates only bytes which changed.
• The standby server for activity recovery on which data are replicated can be as far as it is necessary for you since replication happens through standard IP connections, and at the same time the maximum data protection is provided.
• Will allow to increase efficiency by means of data compression before sending
• Will allow you to use cluster environments with interception of management which will have no normal shortcomings — total memory and geographical restrictions. Thus the program will eliminate system "Achilles' heel" (namely — deniability of memory) and will allow you to locate cluster nodes anywhere.
• Will allow you to integrate workloads with the IT organizations using Windows Server 2008 Hyper-V™ or VMware® ESX
• Will allow you to replicate virtual machines from one server of virtualization on another in real time and to automatically make interception of management of these virtual machines in case of failure or accident.
• The program is available to Windows and Linux and any supports applications, acting in these operating systems

• Simple management and protection of virtual environments - Double-Take Availability 5.3 allows to configure protection of the virtual machine (VM) at the level of a host (server), exempting from need of preliminary software installation. The replication agent automatically is established on each protected virtual machine upon completion of a configuration. The combination of management at the level of the server and detailed replication of each VM in real time provides simple effective protection in management.
• The improved protection of virtual clusters – Remote access to the working documents and processes organized based on Microsoft Hyper-V is provided due to protection of the clustered virtual hosts of Hyper-V on all network WAN which is supported by new Double Take Availability. The clustering of Hyper-V and replication of data in real time by means of Double Take provides the unified access to Hyper-V hosts – both local, and remote. Administrators can also appropriate the IP addresses to a remote system that provides big flexibility in ensuring fault tolerance.
• Expanded support of Microsoft Exchange – Double-Take Availability 5.3 supports Now protection of Exchange 2010 in the Database Availability Group (DAG) environments that can be especially significant for the companies wishing to implement disaster recovery for the DAG systems in environments with low capacity. New opportunities of reduction of file size of the system magazine Exchange also allow Double-Take RecoverNow 5.3 to provide the improved protection of Exchange 2010. The possibility of timing of cleaning of log files on the working server with simultaneous creation of a control point for recovery of Microsoft Exchange on a standby server allows to perform operational recovery from the freshest copies or earlier control points.
• Support of the updated operating systems – Solutions of a line of Double-Take 5.3 (Availability, RecoverNow and Move) support Microsoft Windows Server 2008 R2 SP1
• Simpler and effective recovery of a configuration – Is insufficiently simple to reduce idle times due to increase in resource availability. Return to that, "as was earlier" or rollback of a system can cause still great difficulties, having led to additional idle times. Double-Take Availability 5.3 gives additional opportunities for transition to reserve capacities at failure of both all server, and separate VM that reduces a possible downtime in configuration recovery time. Among the innovations provided to Double-Take 5.3 – a multitasking support at recovery of a configuration and a possibility of comprehensive monitoring of a system.
• The single console and one interface for all transactions – The Vision Solutions Company expanded functionality of the management console and brought management of all modes of protection to one screen. For the organizations placing the data-centers on several platforms and needing a possibility of their consolidation or migration, version 5.3 gives an opportunity of separation of licenses for groups and their associations with each platform. Besides, installation in scales of all company and enhanced capabilities on adjustment of capacity of channels is supported. Along with it, support of recovery of the server after failure (Full-Server Failover, FFO) and also types of tasks for files and folders is added to the single console of management. The administrator also had an opportunity at the same time to carry out one or several tasks.
