What is the difference between fault tolerance and disaster recovery? How does a network administrator decide which backup method to implement?
Below are types of Disaster Recovery:
1. No disaster planning at all - disaster has not even been considered and no planning has been done. Companies without a good disaster recovery plan are living on borrowed time. A disaster will strike: it could be a flood, a collapsed ceiling, an infestation of insects in the wiring, a major earthquake or a terrorist attack.
2. No disaster plan, but good backup procedures - regularly (once every day) back up the data on your computers and store them offsite by using an archival company.
3. Fault tolerance - The next step up in disaster recovery is to build fault tolerance into all of your critical systems. This means installing RAID drives (disk drives which are redundant copies of each other), clustered systems and other types of local recovery procedures.
4. A plan for disaster without any resources in place - Once you have a good backup and archival procedure and your critical systems are fault tolerant, the next step is to put ...
