In our continuing effort to educate on how Backup 2.0 data protection reinvents the process of data collection, transmission, and recovery for backup, Vizioncore is gaining support from the Analyst community.
Senior Analyst Eric Slack at Storage Switzerland offers his analysis of why image-based data protection methods are better than traditional backup and recovery. In the paper, Eric describes how Backup 2.0 solutions like vRanger Pro offer cost-savings advantages including savings in server hardware, backup software by eliminating agents, and administrative overhead. A PDF version of his paper is attached to this blog entry, and can be found in the Storage Switzerland blog site at:
Highlights from the paper:
Image backup is a process that uses server images, like those created by VMware, to capture and protect an organization’s data. This image includes system state, OS, application configurations and data in a single file. It can be created while the server is in production allowing the backup process to complete without affecting the application, effectively eliminating the backup window. This single image can be copied easily to a remote site for DR and also used to produce different types of restores (full server, file, data object).
The traditional (legacy) backup process involves copying discrete files and application data from client servers using backup servers, client server agents and specific software modules to capture, store, manage and restore these data. This current process has remained mostly unchanged at a large percentage of organizations, even with the advent of technologies like VTL, disk to disk backup and deduplication. These developments mostly just leverage traditional backup and focus on making it easier to live with.
But this legacy process manages, moves and records too much (duplicate) data to be called “efficient”. Image-based backup, with products like Vizioncore’s vRanger PRO, may be the way to improve this efficiency and bring some real cost reduction to IT through the backup process. A server image (like a virtual machine VMDK file), taken with a snapshot, or point-in-time copy, includes all a system’s data. Protecting this comprehensive representation of the system is much faster and easier than the file-based process used by traditional backup software. Those legacy systems have to copy thousands of files and manage these discrete data objects throughout the backup and restore process.
