Disaster Recovery- 
as-a-Service (DRaaS)

Backup as a Service (BaaS) stores and secures your data files while Disaster Recovery as a Service stores and secures all the applications, servers, configuration, and data.

BaaS only gives back the vital data through which the business can get back on its feet. The company suffering the downtime has to create fresh records, user settings, etc. As the staff has to work on a smaller capacity with limited resources, the productivity goes down.

DRaaS restores all the servers, applications, user configurations, and data in a few minutes. The company can work at the same pace as it was working before the downtime happened and there is no effect on productivity and profits.

A disaster recovery site, or the backup site, is a virtual location where the company temporarily relocates during an incident.

The presence of this location confirms that the company will be able to continue its operations seamlessly as it was doing at its original location.

The IT architectures with a disaster recovery model failover the VMs during a disaster. The cloud platform, on which disaster recovery is set up, continuously replicates data at different locations.

When the system goes down, the business continues its operations with negligible data loss.

Disaster Recovery as a Service is a cloud service model that enables data backup and IT infrastructure in a third-party cloud computing environment.

Organizations opting for DRaaS can regain access and functionality to IT infrastructure after a disaster.

Companies opting for a fully managed DRaaS will get all the hardware, tools, and solutions through a service provider. It is an effective solution that reduces the downtimes and loss of critical data.

Disaster recovery planning offers superior business continuity. Disasters, natural or man-made, can cause massive damage to the progress of the business. A company should always be ready to get back on its feet in case of a catastrophic event like:

• Natural disasters such as hurricanes, floods, wildfires, and earthquakes
• Equipment failures and power outages
• Cyberattacks

It is a compelling solution to eliminate downtimes and loss of critical data and takes a small fraction of company expenses.

There are majorly 4 types of disaster recovery approaches.

Hot Disaster Recovery - Hot DR is ideally used and absolutely vital for Mission Critical applications such as core financial and banking applications. This involves a quick Recovery Point Objective (RPO) and Recovery Time Objective (RTO).

Warm Disaster Recovery - The focus is on applications and infrastructure with a slightly higher RPO and RTO. It can involve non-core banking applications, DMS, MOSS, and print &file servers.

Cold Disaster Recovery - It takes a longer data recovery period compared to the Hot and Warm DR. It involves a higher RTO and RPO and is used ideally for Non Critical applications.

Backup as a Service and restore - It involves backing up your systems and restoring them from backup in case of any disaster. We implement strategies that help reduce your backup footprint using a method of deduplicating data at each node, job, and site. As a result, you get faster backup and recovery. Cloud4C is known for its global deduplication systems that efficiently execute bare metal recoveries.

RTO refers to the maximum length of time that your given application can be offline. RPO refers to the maximum acceptable duration of time during which data may be lost from your application due to any major incident.

In other words, RTO is focused on the downtime of services, applications, and processes, helping define resources to be allocated to business continuity and RPO is focused on amount of data, as its sole purpose is to define backup frequency.
