Cloud based solutions are all the rage. More and more companies abandon traditional networks in favor of cloud based solutions each day. Interestingly, despite early concerns about security and privacy many companies are turning to cloud disaster recovery systems to protect their valuable data. It appears that service improvements implemented in the last few years have succeeded in allaying the fears of the naysayers.
But it is not enough to say or believe that cloud disaster recovery solutions are capable of meeting the most stringent requirements of most companies. That is because each company is unique and has a different set of needs from other companies. This makes it impossible to apply one set of solutions to all companies. The differences in their sizes, the size of their IT budget, their core activities, and even the nature of their clients make it imperative to have a wide range of solutions to choose from. People at the Cloud Computing Association are continuously looking for ways to improve the systems further.
Here are just a few available options on cloud based disaster recovery systems:
a) An option that places everything in the cloud. With the primary data produced and disaster recovery systems both in the cloud, the response times are almost instantaneous. Cost is also way below that of traditional disaster recovery systems.
b) An option which keeps data on-site but backed up in the cloud. Restoring data to onsite infrastructure can be a bit slow, limited as it is by available bandwidth for data transfer. Its main advantage is having data and backups in different locations.
c) The next option goes a bit further by using the cloud based disaster recovery plan both for backing up data and for restoring data onto virtual machines. The problem on recovered data transfer rates go away. However, the system still does not address possible loss of data on companies that can ill afford to.
d) The best option available makes use of a continuous replication of data onto virtual machines in the cloud. This results in uninterrupted back-up that ensures freedom from loss of data. Under this option, the main data are also kept in the cloud, so recovery is almost instantaneous.
The cloud based disaster recovery system that best suit your company’s requirements is out there. You just need to define those requirements to find it.
