In an article that posted today on Storage-Switzerland, Senior Analyst Eric Slack reports on how image-based backups are simply better. To quote Eric, "Images don't just do backup better, they create a better backup."
Eric opens his report with the following:
Traditional backups require a complex collection of hardware and software to identify, capture, organize and store server data. And, they must do so in a finite (usually shrinking) window of time in order to assure that data is protected. This complexity stems from the structure needed to manage these data sets at the file level. Image backups instead capture only a few files for each server instance and don’t need a complex infrastructure to accomplish this task. This inherent simplicity brings a number of advantages in efficiency and performance, as well as some advanced functionality that traditional backup systems don’t typically provide.
Image backup systems don’t usually require a backup server or media servers and proxy servers to collect and transport data to storage devices. There’s often no need for software agents in the client to interface with the OS or specific applications that it’s running. With less software to install and maintain, and less need for complex schedules of backup jobs, management of an image backup system is much easier.
In his report, Eric goes on to describe the advantages of image-based backup for obtaining faster, more efficient backups; reliable, low-cost and non-disruptive backups; and, reliable restores.
Eric also points out that image-based backup is easy to ADD to existing backup environments. Solutions like vRanger Pro work in conjuction with these environments, to complete backup protection and enable fast full-system rebuild along with file-level and object-level recovery from protected images. Even traditional backup agents gain in protection and recovery levels, as they can be restored more rapidly at recovery sites on new systems to enable faster traditional restore of application data.
