Access "How disk has changed backup"

Published: 30 Oct 2012

Our backup choices are much greater and more complex compared to the days when you simply had to choose a backup application and tape library. Disk has solved the reliability and performance issues that most storage managers have experienced with traditional backup systems, but disk-to-disk-to-tape (D2D2T) has complicated backup and restore processes. Users must now choose from three backup architectures and four types of disk-based backup targets. What follows are the pros and cons of each approach. The traditional backup architecture Before explaining how the different D2D backup options work, it's important to understand the backup systems they'll work with and why you might want to augment those systems with disk. In a traditional backup architecture (see "Traditional backup architecture", next page), software resides on the backup client (the server to be backed up) that allows the backup server to transfer that client's data to tape, disk or virtual tape. The data may be transferred across the network (LAN-based), from the client directly to tape/disk ... Access >>>
