Disaster recovery procedures

What is it?
Disaster recovery procedures are failsafe's to protect IT infrastructure in the event of a disaster. Such as a plan which states what an organisation should do if a disaster occurs such as a fire.

Why is it used?
Having disaster recovery procedures could mitigate risks and prevent disruption to any operations. If the correct procedures are in place then an organisation will have less financial damage when these 'disasters' occur.

Disk failures
Replace disks and restore from backups.

Data loss
Restore data from backups.

Unauthorized modification of data
Restore data via backups.

A contingency plan will also be very beneficial to have.

Evaluation
Disaster recovery procedures are a set of rules that an organisation must follow in the event of a disaster. In IT organisations are very prone to computer related disasters occurring so it is important that a viable and consistent procedure takes place when one occurs. There should be a procedure for most possible computer/system failures. Having these procedures in place can also help quickly mitigate the issue depending on severity.
