Double-Take for VMware
Description
Double-Take for VMware Infrastructure greatly reduces downtime and data loss in virtual environments, making it an ideal component for customers implementing cost-effective disaster recovery and business continuity plans. It is a solution that protects ESX-based virtual machines. Double-Take for VMware replicates the entire virtual machine: the OS, applications and data, allowing you to replicate everything to any location and resume operations with minimal downtime.
Key Features
- No Pre-staged Target Required - Whole VM protection means a replica VM contains an identical configuration as the protected VM, including the OS, applications, all relevant patches and system state. There is no need to pre-stage a target VM for recovery on the second ESX Server.
- Agent-less Installation - No agent software is required on the ESX Server or within any protected VM, providing easy management and rapid deployment of protection scenarios.
- Virtual Infrastructure Browsing - The Double-Take for VMware Infrastructure management interface leverages the logical groupings and hierarchies available in VMware VirtualCenter, making it possible for an administrator to easily navigate through configured virtual machines and select them for management and protection.
- Compression Options - Double-Take for VMware Infrastructure provides options for compressing the replicated data, providing flexible trade-offs between host system resource consumption and network bandwidth usage.
- Replication Frequency Options - Double-Take for VMware Infrastructure provides the flexibility to configure the frequency of change replication based on either the amount of change or the time that has elapsed since the last replication window.
