Once the servers are added to the system, managing jobs happens from the console. The features and capabilities of Double-Take are managed by the Double-Take console application. Anything running on the host will be managed with the appliance, reducing the overall management surface of the application and its jobs. This is a huge option because it requires no installation inside the guest machines. With an agent installed, backups can work with the guest and its applications to ensure there are no issues that could cause problems for the backup.įor VMware environments, Double-Take 7.0 can deploy a virtual appliance to operate at the hypervisor level and allow agentless backup of guest machines. This can be useful for guest machines that don't have special considerations needed for the applications or configurations within the guest machine.įor virtual guest machines that might have applications with configurations or functionality that's backup-aware (SQL Server or Exchange Server come to mind) Double-Take supports the use of agents that get installed on the guest machine. Agentless backup allows the hypervisor to back up the guest file as one unit with no account for any applications or guest-based data. The key new feature in Double-Take 7.0 is its support for both agent-based and agentless backup for virtual environments. Here, there is a separate way to handle this.
Other solutions allow recovery to different hardware and replication to off-site servers but this happens as a function of the applications backup solution. This keeps the focus of each feature (and, yes, license) on the action it performs the best. Including a completely different set of components to help with migration of servers and data, outside of "restoring a backup" to new hardware was a good idea because it separates the components of the solution. The other is Double-Take Move, which allows migration of a server (or its data) to a different physical or virtual machine (VM). This is the option to use for general everyday backup practices. First is Double-Take Availability, the component that allows an application, a clustered workload or an entire server to be backed up. In keeping with previous releases, Double-Take 7.0 offers two options for backup and migration.

While that's an important feature for Windows shops, Vision Solutions added some other key improvements to Double-Take that are worth noting. In my recent roundup of backup and recovery solutions that use Windows Azure as a target (see " Use Windows Azure as a Backup Target," November 2013), I pointed to the new Double-Take 7.0. I've spent some time with the recently updated Double-Take from Vision Solutions Inc.
The concept of disaster recovery can work across solutions, which helps, but the ins and outs of the solution are what make it stand out and can make or break a product. It's certainly not that disaster recovery is too difficult to master, but the challenge comes from the abundance of solutions available and constantly updated in this space.
Backup and disaster recovery are functions that many IT professionals want to manage themselves.
