5 alternative approaches to disk backup

Overview

As an increasing number of IT organisations look to replace tape, their leading alternatives include the following:

• using straight disk, fronting a tape library
• using a cloud-based backup service
• using data deduplication backup software
• using a disk-based backup appliance
In view of this often confusing landscape, this white paper will discuss the factors to consider when evaluating any of these alternatives, including a framework for assessing the value to IT for each approach.
