Chapter two from the book The Definitive Guide to Exchange Disaster Recovery and Availability, by Paul Robichaux, explores fundamental principles behind disaster recovery and explains technical solutions you can use to improve recovery within your organization.
Various backup methods -- full, incremental, differential and copy backups -- are examined. The pros and the cons of several disaster recovery technologies are also covered -- including backup to tape, disk-based multi-stage backup and restore, vendor solutions, VSS and replication.
Once you understand the myriad disaster recovery technologies, you'll review the following design variables, consider their benefits and drawbacks, and discover how each factors into an effective disaster recovery plan:
- Onsite vs. offsite
- Recovery vs. redundancy and resiliency
- Service providers vs. do-it-yourself
- Planned vs. unplanned
Paul Robichaux provides an easy to understand look at the basic technical building blocks of a good Exchange Server disaster recovery plan. Replication, VSS and conventional backup and restore technologies all have their place. But do you know which ones you should be using to get the maximum benefit? Read this chapter to find out.
