What is disaster recovery?
Disaster recovery is the ability to resume complete IT operations after a disaster such as a power outage, cyberattack or natural disaster.
What is disaster recovery versus data backup?
Both disaster recovery and data backup operations involve making copies of data to protect against loss of data, corruption, compromise or theft. But while data backup may involve copying a portion of data to another server that is on-site or off-site, disaster recovery involves copying a complete image of disk drives and servers to an off-site location that would be unaffected by a disaster at the primary data location.
What is disaster recovery RPO?
RPO refers to recovery point objective, which is the age of IT processes and data (time since creation or modification) that an organization needs to recover after a disaster. A lower RPO stipulates that fewer transactions and less information are lost during an unplanned outage. A low or near-zero RPO requires more frequent backups, resulting in increased costs.
What is disaster recovery RTO?
RTO stands for recovery time objective, which is the amount of time it takes to recover operations after an outage. A low RTO means faster recovery, but typically at a higher expense.
How is disaster recovery performed?
To enable disaster recovery, organizations must back up data on a regular basis – once every 24 hours is a common schedule. These disaster recovery backups are saved to disk or tape and stored off-site or saved in cloud storage. In the event of a disaster, the latest copy of data is recovered from storage in order to enable IT operations to resume.
What are the benefits of effective disaster recovery?
Effective disaster recovery enables organizations to recover quickly after a disaster with minimal loss of data. Superior disaster recovery technology should help to reduce disaster recovery costs by minimizing the amount of data to be copied through deduplication, by accelerating backup speed in order to minimize backup windows, and by reducing the amount of time that it takes IT teams to configure, manage and perform disaster recovery operations.
