Data resilience solutions are an essential element of business continuity plans and, as organizations go through digital transformation and become more dependent upon their IT services, the need for data resilience has grown. These solutions must not only support today’s hybrid multi-cloud IT service delivery environment, but also exploit the new capabilities that this provides. This report covers how the data resilience solutions provided by Arcserve meet these challenges.

1 Introduction

As organizations go through digital transformation, they become much more dependent upon their IT services to support the business, and this has increased the potential business impact of accidental mistakes, natural disasters, and cyber incidents. This makes business continuity planning an essential element in the digital transformation process. The use of data resilience solutions and disaster recovery services are essential elements of business continuity plans, and these must support today's multi-cloud hybrid IT environment.

Data is the most important business asset of the modern enterprise and needs to be protected against unwanted events such as malware as well as physical or logical damage to the storage devices or the IT installation. The prevalence of ransomware attacks where criminals demand payment to restore access to business-critical data has emphasized the need for data resilience. In addition, the changes in working patterns following the COVID-19 pandemic have also increased the risks to data as people work from home. As well as increasing susceptibility to ransomware, unmanaged end user equipment often lacks proper data protection.

When IT services were delivered exclusively on-premises, backup solutions were used to make copies of the data storage media (typically tape and disk) which were then stored in separate locations with additional safeguards against fire and theft. The physical transfer of these media added delays and additional risks into the backup and recovery processes. However, IT services are now delivered through a hybrid model which introduces new challenges and provides new opportunities.

In today's hybrid multi-cloud IT environment, some services remain on-premises while others are delivered through the cloud. There is a temptation to believe that the use of a cloud service removes the need for the customer to consider the resilience of their data. The responsibility for data held in cloud services is shared between the tenant and the service provider and there are many situations where the tenant is responsible for the resilience of their data. In addition, where the hybrid model leads to multiple data protection solutions being used, which increases the management burden. Therefore, it is especially important to implement a single solution that covers all the different use cases.

The cloud also provides an alternative location for backed-up data since major cloud services are usually delivered from highly secured datacentres in multiple geographic locations. This provides the possibility to store the backed-up data with a high degree of resilience as well as reducing the delays and risks of physical transfers. Modern data resilience solutions can be expected to offer backup to the cloud as an option.

The time criticality of digitized business services has increased the need for an always on architecture. Today's e-commerce, financial services, and critical infrastructure demand continuous availability where even seconds of downtime could lead to severe damage. This always on architecture depends upon continuous data replication to ensure business continuity when individual elements fail.

All organizations need to consider the risks related to the availability of their business data and respond appropriately to mitigate these risks. This means investing in backup products and disaster recovery services and immutable storage solutions to ensure data resilience. It is vital that the chosen approach is adequate for the modern digitally transformed hybrid IT environment.
