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.

Common Strategies
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.
