Welcome to part three of our blog series, Understanding Backup and Disaster Recovery as a Service. In part two of the series, Recovery Objectives, we concluded that organizations that have backup only and no disaster recovery will continue to experience painful recovery objectives in addition to downtime and loss of data.
In this article, we will consider how disaster recovery as a service eliminates painful recovery objectives while minimizing downtime and loss of data.
Data Backup vs. Replication
How replication eliminates painful recovery objectives.
Knowing the difference between backup and replication is critical to choosing which solution best suits your organization. By definition, backup is the process of sending a copy or copies of files, images or databases to an external media or offsite location for storage in case your original data is lost or corrupted.
Replication refers to copying data and moving it between an organization’s primary environment and a secondary offsite disaster recovery location. Replication means having an exact replica of your physical or virtual system (servers), applications and data in an offsite location. Your primary location is synchronized with your replica at the offsite location. After the first replication, further replications that occur in periodic snapshots will simply synchronize the changes that were made since the last replication.
While backup is designed to provide data protection and archiving, replication is designed to reduce Recovery Time and Point Objectives (RTOs and RPOs) by providing very fast recovery. It ensures business-critical applications and systems are always available even after an outage.
In our previous article, we concluded that RTOs essentially define the time it takes to recover from an outage while RPOs define the acceptable amount of data loss that a business can tolerate. Replication eliminates painful recovery objectives, minimizes downtime and loss of data through;
- Reduced recovery time and point objectives
- Fast recovery speeds through instant failover
Backed up data will only be as recent as the last time it was created, so when you rely on backups for your disaster recovery strategy, the RPO will be higher compared with replication. You should consider that data restoration takes some time due to data decompression. Depending on the data size, the restoration of a backup will generally take much longer to be up and running than replication.
In some businesses, one day of dysfunctional systems may be tolerable. However, in the majority of cases, downtime results in high revenue losses. Replication provides an alternative solution to companies with a low tolerance for time and data loss.
Replication provides applications with near to zero RPOs. When configured with redundant server infrastructure, replication can also provide near to instantaneous RTO. This is all because the data is in its original size and ready to be used on hardware that is identical to the original. On average, you can expect data to be recovered within minutes.
Pepea Disaster Recovery as a Service (Pepea DRaaS)
This service is made possible by cloud computing in that cloud service providers such as ourselves replicate your entire production site, from files, systems, applications, to physical or virtual machines to an offsite data center. This means that in an offsite location, a virtual replica of your entire production site is available with all changes and addition to data being replicated in real-time or in periodic snapshots. When a disruption occurs, your organization can immediately continue working from the live offsite location until you are able to restore operations. It is an instantaneous process.
How will Pepea DRaaS benefit your business?
- Meet industry recommended recovery time objectives and recovery point objectives with limited downtime and instant failover
- Guarantee business continuity with an “engine running” virtual data center solution, fully configured as an extension of your existing network. This helps guarantee a fast recovery with minimal business disruption.
- Flexible recovery options where you can restore one virtual machine or your entire data center –quickly and reliably.
- Save on costs as Pepea DRaaS is much cheaper than traditional DR sites. No management costs and people hours are needed to invest in maintaining and testing the DR solution. Also, the overall cost of us setting up and managing the DR for you in our cloud is only a fraction of the revenue loss or potential reputation damage that you could incur in case the opportunity to avail a DR solution is not exercised.
- Easier testing as failover testing is now as simple as pointing and clicking,
- Minimized downtime as our server with the associated applications and data can be brought up within minutes.
- Pepea DRaaS requires fewer operational resources. This results in significant savings in software licenses and hardware, allowing the organization to increase its budget in other areas of operation, such as marketing and R&D.
Our Secure DRaaS allows your IT workloads to be replicated from virtual or physical environments to our advanced security Pepea cloud infrastructure. With over a decade of disaster recovery expertise, we can go far beyond simple backup to ensure all your key workloads are protected – and the disaster recovery process is tuned to your business priorities and compliance needs.
The question of disaster recovery is whether to do it yourself (DIY) or outsource a cloud service provider. Stay tuned for our final article in the series Understanding Backup and Disaster Recovery as a Service, DIY or DRaaS?
