What is cloud disaster recovery?
Cloud Disaster Recovery (DR) is a set of plans that enable effective backup and restoration of data and applications used by cloud computing users. The goal of Cloud DR is to help organizations with a way to recover data and/or implement a robust strategy in the event of a man-made or natural catastrophe.
The Benefits of Cloud Disaster RecoverySome of the key benefits you can gain with backup disaster recovery in the cloud include:
- Improved data protection: Cloud backup ensure that your data is recoverable and protected. With cutting-egde encryption and security practices, your cloud-based data is highly secure. The popular myth of the cloud being less secure is just that. A myth.
- Ease of use: Cloud BDR solutions tend to have easy-to-use web- based management and user interfaces. At most, cloud solutions require a light-weight agent on devices used for data synch to the cloud, so you have minimal maintenance.
- Low Total Cost of Ownership (TCO): Zero capital expense and predictable subscription pricing keep total cost of ownership low.
- Fast implementation: Rapid deployment in a matter of minutes with set-up and configuration wizards.
- Agility and scalability: Because it’s cloud-based, increasing or decreasing your storage capacity should be painless. Try to avoid any tiered pricing as you increase data volumes.Most cloud solutions interoperate with existing storage devices, applications and operating systems.
Factors to consider In setting up a DR plan, triage plays a keyrole in determining the usage and cost of the infrastructures that get involved in the process. Several factors come into play when implementing DR plans. They include :
Security of data and applications Network Bandwidth to enable fast backups and recovery times Reliability of the cloud provider
What are the main approaches to Cloud DR
- 1) Replication to virtual machines in the cloud. For applications that require aggressive recovery time and recovery point objectives (RPOs), as well as application awareness, replication is the data movement option of choice. Replication to cloud virtual machines can be used to protect both cloud and on- premises production instances.
- 2) Back up to and restore to the cloud. In this approach, data is not restored back to on-premises infrastructure; instead it’s restored to virtual machines in the cloud. The restoration can be done when a disaster is declared or on a continuous basis (pre-staged).
- 3) Back up to and restore from the cloud. Applications and data remain on- premises in this approach, with data being backed up into the cloud and restored onto on-premises hardware when a disaster occurs. In other words, the backup in the cloud becomes a substitute for tape-based off-site backups. With FSB Cloud platform, you have great flexibility as we have a variety of options on the cloud DR implementation that best suits your needs at every point in time.
