Backup controls
The Microsoft Azure Backup Server (MABS) protection agent manages backups to and restores from the MABS Azure Stack Hub VM.

Protection groups are used to configure and manage data protection. A protection group is a collection of data sources that share the same protection configuration. The protection configuration is the collection of settings common to a protection group, such as the protection group name, protection policy, storage allocations, and replica creation method.

At regular intervals that you can configure, MABS creates a recovery point for the protected data source, which is a version of the data which can be recovered.

Availability and resilience

Guaranteed availability
If provided on a customer site, availability cannot be provided with an SLA as Exponential-e cannot provide an SLA for customer owned power and security. The appliance is a fully redundant hardware design to remove single points of failure and would therefore be considered a 99.9%+ architecture. If deployed in an Exponential-e Data Centre, a single site solution is provided with 99.9% availability, or 99.95% for a dual site deployment.
Approach to resilience
Azure Stack Hub is provided as a pre-validated configuration designed by Dell Technologies and approved by Microsoft. The system uses a standard N+1 resilient architecture with no single point of failure. Further information available on request.
Outage reporting
Service status is reported in real-time via the Azure management plane. Additionally, Exponential-e report outages via: a customer dashboard and email alerts. Exponential-e are ISO2000-1 accredited and follows standard ITIL conformant processes to notify affected customers in the event of a service outage.

MAC 4.1: Delivering environmental benefits
Exponential-e is committed to continually improving environmental performance and monitoring environmental effects from our activities to identify potential areas for improvement.
We are accredited and operate within internationally recognised management standards (9 ISO’s) of which two are focused on Environment Management (ISO 14001:2015) and Energy Efficiency (ISO 50001:2015). This standard specifies the requirements for establishing, implementing, maintaining and improving an energy management system with a systematic approach in achieving continual improvement of energy performance, including energy efficiency, energy security, energy use and consumption.
Critical to our core operation is our national network infrastructure, and cloud infrastructure. Thanks to unique cooling technology, our Data Centres are the most environmentally efficient in the UK. They save customers on average around £1.1 million per megawatt and 6,000 tonnes of taxable carbon annually compared with an average Data Centre facility.
Some of the practices deployed to achieve carbon footprint include:
• All our Data Centres are ISO 14001 accredited with robust environmental management systems
• Procuring consumed energy from sustainable energy sources wherever possible
• Ensuring the use of hot/cold aisle cooling design in our Data Centres, which reduces energy consumption as the cooling is more efficient and helps our customers to reduce their carbon footprint
• Using the latest virtualisation (VDC) technologies to ensure the most efficient utilisation of hardware resulting in the overall optimisation of our client’s infrastructure. Our VDC delivers dedicated processing instead of having multiple, underutilised physical servers, which helps minimise our environmental impact
• The business considers the environmental impact of goods and services within procurement processes. Working with suppliers, contractors and indeed clients to lessen the environmental impact of their operations.
• Homeworking practices have been developed to allow homeworking whilst preserving security of company data and access to IT systems.
Covid-19 recovery

Covid-19 recovery

MAC 1.5: Improvements to workplace conditions
Exponential-e operates to ISO22301 – Business Continuity Management System (BCMS) standard. This means our critical business functions have existing and proven business continuity plans which are reviewed, exercised and/or tested regularly.
In line with this standard, we have taken the following steps:
• Implemented flexible working arrangements for any high-risk employees, or employees who are unable to travel due to other reasons relating to the coronavirus (Covid-19)
• Conducted a full Business Impact Analysis (BIA), considering shift patterns, physical segregation and cover arrangements across all of our core 24*7 service operations to maintain the appropriate resource levels
• Implemented ongoing monitoring of our workforce and skills capability to ensure all our personnel are multi-skilled and have monitoring in place to address any weakness or gaps
• Completed capacity planning and forecasting of the current and future levels of resource utilisation, taking into consideration the enactment of multiple Business Continuity scenarios
• Introduced enhanced presence of our on-site cleaning personnel throughout the day and evening to ensure the cleanliness of our facilities is maintained
• Initiated a change freeze across our core platforms to allow our key resources to focus on service availability and reacting to changes our customers may require
• Limited any non-essential travel to customer or vendor sites, making the best use of remote technology to ensure we maintain our quality of service and open engagement throughout this period of uncertainty.
Exponential-e has since initiated remote working at a larger scale in a controlled manner. Our Head Office has implemented a Hybrid working model for all staff who are able to work remotely for two days a week and in the office for maximum of three days a week. This also reduces our carbon emissions through travelling and heating/lighting of office premises.
Tackling economic inequality

Tackling economic inequality

MAC 3.1: Diverse supply chain
Exponential-e maintains a policy of working with diverse partners and SME organisations where there is a defined benefit to our customers, and where the limitations of the contract or security requirements are not at risk in any way, which must be our overriding consideration. We reach out to our wider supply chain partners should any subcontracting opportunities arise during the contract duration.
If any strategic supplier fails to deliver and thus breaches the terms of their contract, we will invoke the use of alternative and pre-qualified suppliers. We plan for these contingencies and maintain a supply chain that does not rely on any single source of fulfilment.
MAC 3.2: Supporting innovation & disruptive technologies
We will hold regular engagements, in which we will review, present, and collaborate on new technology and commercial initiatives throughout the life of the contract, and (when applicable), driving equality throughout our supply chain.
MAC 3.3: Scalable & future-proofed methods to modernise delivery/increase productivity
We work with innovative and agile supplier organisations who bring innovative technology solutions to market, by providing a framework to enable the deployment of their services within our stable and risk-controlled corporate environment.
MAC 3.5: Manage cyber security risks
Exponential-e maintains Cyber Essentials Plus and ISO 27001 accreditations. Additionally, Exponential-e operates a 24 x 7 x 365 CSOC desk to alert for any cyber security issues and potential risks. Our CSOC is built using trusted Unified Security Management (USM) technology, which unlike other SIEM software, combines powerful SIEM and log management capabilities with other essential security tools such as asset discovery, vulnerability assessment, intrusion detection (NIDS and HIDS) to provide a centralised security monitoring of networks and endpoints, all through a single pane of glass.
Equal opportunity

Equal opportunity

MAC 5.1 Provision of inclusive working environment
As a commitment to reducing the disability employment gap Exponential-e has adopted a hybrid working model that allows flexibility. Hybrid working, sometimes referred to as "blended working", is a form of flexible working that allows employees to split their time between attending the workplace and working remotely (typically from home).
MAC 6.1: Tackling inequality in the contract workforce
We are committed to equal pay for the contract workforce. To address our gender pay gap, we have a number of initiatives in place, to not only attract more female talent, but to encourage a more balanced, and rewarding workplace:
• Working with educational institutions to help attract more women into STEM focused roles
• The data shows that the disparity in the bonuses paid is due to the fact there a very few women in senior sales positions. We have a junior sales mentoring programme for both men and women, equally, to encourage progression into senior sales roles, especially for women
• Training is available to cover areas like Equality & Diversity, Unconscious Bias
• We have established a Women’s Working Group who will assist in supporting the attraction, retention and promotion of our female talent across the business
• Flexible working arrangements for all staff to encourage work life balance.
Placement Programme & Apprenticeships
Every year Exponential-e offers placements and apprenticeships to students whose degrees would benefit from working in an operational technical environment. The students are paid, which allows them to practice the theory learnt in the classroom in a real world environment; while also supporting themselves financially.
As part of our commitment to the Government’s Apprenticeships Levy Programme we actively work with registered apprenticeship companies to provide upskilling opportunities to employees across a range of subjects.


MAC 7.1: Support health and wellbeing in the workforce
All staff are eligible to join our Private Health scheme (on completion of probationary period) run by Vitality which actively encourages physical and mental wellbeing through a broad variety of programmes design to promote and incentivise wellbeing.
Exponential-e has also implemented the six standards in the Mental Health at Work commitment and where possible follows the mental health enhanced standards in Thriving at Work, as follows:

1. Prioritise Health Wellbeing Through Systematic Programme of Activities
Exponential-e partnered with Care first as an Employee Assistance Programme (EAP) to provide online and counselling services to all our employees.
2. Work Design & Culture Drives Mental Health Outcomes
Exponential-e offers the following benefits package for all eligible employees - Life Assurance, Private Medical Scheme, Employee Assistance Programme, Ride to Work Scheme, Season Ticket Loan, Employee Referral Scheme and Purchase of Holiday Scheme.
3. Promote Open Culture Around Mental Health
Exponential-e has seen a huge shift in attitudes to mental health and we promote and support employees to think and talk about their mental health which subsequently helps the organisation to thrive.
4. Increase Organisational Confidence & Capability
Exponential-e recognises the importance of leadership and management development and provides programmes designed to upskill our managers and strengthen our leadership capabilities.
5. Provide Mental Health Tools & Support
Exponential-e partners with Care first as an Employee Assistance Programme (EAP) to provide online and counselling services to all our employees, including a series of webinars including stress awareness, social anxiety, long Covid, how weather can affect mood and behaviour, financial wellbeing, and breaking bad habits.
6. Increase Transparency/Accountability Through Reporting
Annual Employee Opinion Surveys are used to drive improvements. A monthly Employee Engagement Pulse Survey helps to keep our finger on the pulse of the organisation.
