What do we understand when we say the word disaster – sudden loss or damage of something. What do we do when we suffer or face a disaster? We start to recover from it. Let us consider a shop is on fire. Firemen come and put out the fire. That is a disaster for the shop owner. Now what will the shop owner do? He or she would take things that are not damaged by the fire and that are recovery. Same goes for your data on a computer or network or anywhere. Also when major disturbances occur in technical infrastructure even that is a technical disaster.
Disaster Recovery Solution refers to set of procedures to follow when the technical disaster occurs so that cloud infrastructure still works. Companies offering cloud computing services handle these types of technical disaster very effectively like in Nuvolat Cloud Group you get a capable technical team that helps you at every step.

Strategies for Disaster Recovery
You have options as to different solutions for Disaster Recovery in your cloud computing. They are –
Managed Applications and Managed DR
A popular option is to place both primary production and disaster recovery instances to the cloud and both will be handled by a managed service provider (MSP). By doing this the user is availing to the benefits of cloud computing. The usage-based cost will be on-premises infrastructure. You’re deferring DR to the cloud or managed service provider instead of doing it yourself. The user needs to be careful with choice of service provider and needs to negotiate appropriate service-level agreements (SLAs).
Backup to and Restore from the Cloud
In this approach, the applications and data remain on-premises, with data being backed up into the cloud and restored onto on-premises hardware when a disaster occurs. Hence the backup in the cloud becomes a substitute for tape-based off-site backups.
Backup to and Restore to the Cloud
The benefit of this approach is that data isn’t restored back to on-premises infrastructure; instead, it’s restored to virtual machines in the cloud. This cannot be achieved by cloud only so it requires both cloud storage and cloud compute resources. The restore can be done when a disaster is declared or on a continuous basis (pre-staged). Pre-staging DR VMs and keeping them relatively up-to-date through scheduled restores is crucial in cases where aggressive RTOs need to be met.
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. In other words, replication is suitable for both cloud-VM-to-cloud-VM and on-premises-to-cloud-VM data protection.
Final Words
Recovery of data is very important. Loss of data can result in loss of money or important information being lost forever. Backing up this information with Nuvolat helps you while facing any technical disaster and hence prevents you from suffering from any loss.
