Businesses have become aware of the need for rapid back-up and disaster recovery. Disk-based, real-time data protection and disaster recovery addresses this problem, says Simon Campbell-Young, CEO of distributor Phoenix Software.

However, he says, many companies don’t know which data protection and disaster recovery solution will best suit their business, and often end up installing the incorrect solution.

Products must be evaluated according to a company’s needs, but there are essential components that should not be negotiable, says Campbell-Young.

A backup must have integrity and the ability to modify schedules. In addition, it should be easy to restore to different hardware.

“Not all back-up products are created equal. In order to efficiently and effectively protect data in real-time, it is critical that the solution uses sector-based imaging – as opposed to file or block-based imaging. Sectors are the smallest possible unit of measure on disk systems. Protecting data and databases at the sector level helps to minimise the amount of data moved across the network,” Campbell-Young explains.
