What is Disaster Recovery as a Service
Disaster Recovery as a Service (DRaaS) is the act of maintaining functionality of critical IT systems in the event of a disaster as offered by a business in exchange for compensation. Disaster recovery is the part of business continuity planning that focuses on IT. DRaaS usually includes, not only data restoration in the event of a disaster, but also planning, testing, reporting, analysis and documentation.
Examples of Disasters
Disasters that could incapacitate critical IT systems include both natural and man-made occurrences. Some examples are listed below:
- IT virus/bug
- Failed Change Implementation
- Hazardous Spills
- Engineering Failures
Disaster Recovery strategies have become more instantaneous as new technology is developed. The following are common strategies for copying data to a location separate from where central systems are housed, starting with the simplest and ending with the most advanced.
- Backups made to tapes and physically taken to an offsite location.
- Backups made to a boot disk and automatically copied to an off site disk.
- Data is replicated to an off-site location.
- Private Cloud solutions.
- Hybrid cloud solutions.
- High availability systems.
