Veeam and ExaGrid cut backup time in half for Trustpower

Veeam and ExaGrid are the core of our backup and replication strategy. The way Veeam integrates with VMware and manipulates the virtual environment is superb. We have cut our backup times in half, and the seamless movement of data between our data centers has been invaluable to the company. I wouldn’t be comfortable with any other product combination for backup and replication in our environment.

The Business Challenge

In a remote island nation like New Zealand, ensuring constant network connectivity is notoriously challenging. As a leading power company and Internet service provider (ISP), Trustpower relies on uninterrupted network availability to provide its customers with an optimal Internet experience.

When ISP Systems Engineer, Gavin Sanders, joined Trustpower five years ago, they had no solid backup strategy in place. Data restores were not being regularly tested, making the business vulnerable to potential data loss. The company was “primarily using HP equipment back then,” he shared, backing up data using HP backup software to HP tape libraries, and spinning disk NAS units. The software and physical storage solution were cumbersome, expensive, and did not dedupe or compress backups effectively.

This was problematic from a business standpoint, as any downtime in the network and servers could impact Trustpower’s service delivery – from customer service, email communications, and ability to retrieve customer data, to the worst-case scenario of customers not receiving any network service at all.

The incumbent backup solution was not satisfactory as it could not ensure recovery of the production environment in the event of downtime, which could limit their ability to provide customers with reliable Internet service. Furthermore, a physical storage and backup system was not very suitable for a virtual environment. Sanders explained, “We really needed a reliable solution that was very well-integrated and designed to work with VMware.”

In addition to a powerful backup solution that could keep their networks and servers running 24/7, Trustpower also needed a dedicated backup target system that was cost-effective, self-sufficient and offered strong deduplication. With newly opened data centres in New Zealand and Australia to increase proximity to its customer base, the ISP also needed a reliable replication tool that could move their data between data centres.

Lastly, the customer support provided by the incumbent solution was often unavailable at a time zone suited to the New Zealand region and as a result, Trustpower had to factor in long waiting times. Sanders shared, “We’re quite remote, and if we do need support, we’d like it to be pretty instant as support is a priceless lifeline in the event of a crisis.”

The Veeam-ExaGrid Solution

After more than 10 years of using Veeam solutions in his previous roles, Sanders was confident in Veeam’s backup performance, especially in virtual environments. He introduced the Veeam Availability Suite to Trustpower’s ISP business, initially only as a backup solution but later as a replication tool as well. Veeam now safeguards the ISP’s mail system and other critical services that run on over 50 virtual servers.

Sanders elaborated, “One of the great benefits of Veeam is its granularity in backup – I can restore entire virtual machines or drill into backup images to restore files - for example, pulling out individual mailboxes or messages from our mail platform backups very easily. So, if any of our customers accidentally deletes important email, we can help them restore it.”

To store and protect the ISP’s main production data, Trustpower chose a mixture of Pure Storage and HPE Nimble for their primary storage, as both vendors were validated by Veeam and integrated well, allowing Sanders’s team to do snapshots and restores seamlessly. Similarly, for the secondary storage of backup data, Trustpower wanted a Veeam-validated system that would also work well with VMware.

In 2018, Sanders attended the VeeamON Forum in Auckland where he met an ExaGrid representative who explained how ExaGrid’s backup solution integrates seamlessly with Trustpower’s existing virtual environment and Veeam backup system. Trustpower was assigned an ExaGrid support engineer to take Sanders and his team through the evaluation and installation process, offering close regional support throughout installation and through the life of the product. ExaGrid provides a support package in each time zone, which includes responsive support from a level-2 engineer, opt-in remote system monitoring, next-day shipping of hot-swappable hardware replacements, and free software upgrades.

By implementing the Veeam-ExaGrid solution it enabled Trustpower’s ISP ICT team to establish a nightly backup schedule and convert geographically diverse passive sites into active sites that cross-replicate backups for greater data protection. Data is backed up to the local ExaGrid system and then cross-replicated to Trustpower’s multiple sites, using ExaGrid and Veeam’s replication technologies, so that data is available and recoverable from any of its sites. Sanders has tested the data restoration process and is pleased that he can recover data quickly and keep customers connected to the Internet. “I’m able to sleep better at night, with the confidence that we can restore critical services if required. After all, a backup strategy is only as good as the last validated restore,” he said.

ExaGrid writes backups directly to a disk Landing Zone which results in the shortest backup window. ExaGrid’s Adaptive Deduplication performs deduplication and replication in parallel with backups while providing full system resources to the backups for the shortest backup window. Once complete, the onsite data is protected and immediately available in its full undeduplicated form for fast restores. ExaGrid can use Veeam’s Instant VM Recovery feature to quickly recover a VMware virtual machine (VM) by running it directly from the ExaGrid appliance if the primary storage VM becomes unavailable, ensuring mission-critical VMs and applications are always available to the business.

Sanders concluded, “Veeam and ExaGrid are the core of our backup and replication strategy. The way Veeam integrates with VMware and manipulates the virtual environment is superb. The combined Veeam-ExaGrid solution has cut our backup times in half, and the seamless movement of data between our data centres has been invaluable to the company. I wouldn’t be comfortable with any other product combination for backup and replication in our environment.”

“Our solution now is completely VMware, Veeam, and ExaGrid. It’s solved our problems and with the success of this roll-out, we plan to replicate this infrastructure more widely across our business network,” said Sanders.

The Results

  • 50% reduction in backup window
    Moving from an outdated physical backup storage system to Veeam and implementing ExaGrid’s Adaptive Deduplication process, Trustpower streamlined its backup window by 50%.
  • Maximum data protection with replication to multiple sites
    Veeam and ExaGrid’s combined solution has allowed the business to replicate backups to the extended data centre network allowing near instant access to data across several locations, and reliable recovery if production storage fails.
  • Strong support and foolproof products vital for New Zealand company’s success
    For a company that requires 24/7 connectivity in a remote location like New Zealand, timely support from the ExaGrid staff has made a world of difference. As for Veeam, the product is so intuitive that “it just works”.


Trustpower Limited is a New Zealand-based company offering Electricity, Internet, Phone and Gas services and is listed on the New Zealand stock exchange.

Trustpower’s electricity generation has a strong focus on sustainability, with 38 hydro power stations across 19 hydroelectric power schemes.


Trustpower’s Internet Service Provider (ISP) business used another competitor’s software, tape and NAS backup system and had faced some reliability and performance issues. The company wanted to de-risk the business against potential downtime disrupting its network services, and subsequently, the Trustpower customer experience. With the business expanding and opening more data centres across New Zealand and Australia, Trustpower needed a reliable backup and replication tool with the ability to replicate and move data across multiple sites running compute services on a VMware platform.
