Protect your data with backups and a tested recovery plan

We agree what to protect, how often to back it up and how recovery will be tested, with results your team can use.

Nerdster helps businesses protect their data and test recovery from an outage or attack. Backup frequency, retention, recovery targets and testing are agreed for your systems and business priorities.

The short version

How we can help

We agree which services you need, the support hours and the price in writing before work starts.

  • Automated daily backups with offsite replication
  • Microsoft 365 backup including Exchange, SharePoint, and Teams
  • Bare-metal server recovery and VM replication
  • Disaster recovery as a service (DRaaS)
  • Quarterly recovery testing with documented results
  • Ransomware-resistant immutable backup storage
  • RPO and RTO planning aligned to business requirements
  • Business continuity plan development and review

Would your backup actually restore?

Plenty of firms discover their backups do not work on the day they need them. The jobs were running. The logs looked clean. Then the restore failed on a corrupted image, an expired credential, or a configuration change nobody accounted for.

Backup and disaster recovery is not about having backups. It is about having backups you have restored from, and a plan for the day your primary systems stop.

What a business backup and disaster recovery service covers

We back up what your business depends on. Servers, workstations, Microsoft 365 data across Exchange, SharePoint, OneDrive and Teams, line-of-business databases, and your cloud infrastructure. Everything is encrypted in transit and at rest, held in UK data centres, and replicated to a second UK site.

Microsoft 365 deserves particular attention. Retention, version history and restore options vary by workload and configuration. A backup review should identify the data covered, retention periods, exclusions and restore process. Microsoft describes its separate Microsoft 365 Backup service here. We compare your existing protection with the recovery requirements before proposing changes.

How to stop ransomware reaching your backups

As we set out in our guide to ransomware in 2026, the more capable ransomware variants go for your backups first. They find the repositories, encrypt or delete them, and only then encrypt production. At that point your choices are paying or starting again.

Correctly configured immutable storage prevents protected backups being changed or deleted during their retention period. It should sit alongside separate access controls, monitoring and restore tests; immutability alone is not a complete recovery plan.

DRaaS: failing over to a working environment

Where prolonged downtime is not survivable, disaster recovery as a service keeps a live replica ready. Your critical servers and applications replicate continuously to our cloud recovery platform. If the primary site goes down — ransomware, hardware failure, fire, flood — we fail over to that replica.

Your team connects over VPN and carries on working while we deal with the primary site. For financial services clients this is not a nice-to-have: FCA operational resilience and DORA both require you to show recovery within defined tolerances.

Bandwidth is the constraint people meet last and feel most. Continuous replication, and any restore of size, are governed by your upload speed, and business broadband is asymmetric — commonly around 75 Mb up against 550 Mb down. A dedicated line is symmetric, which is why recovery targets measured in hours usually assume one. If your recovery time objective is tight, price the line alongside the backup design rather than after it.

We test the failover every quarter, document the result, and adjust the plan as your environment changes. So when a regulator asks how you would recover from a major incident — as they do of hedge funds and every other regulated firm — you hand them the report.

What you get from us

Proof your backups restore

A backup job that reports success is not the same as a restore that works. We test recovery every quarter and give you the documented result, so any failure surfaces in a test rather than in a crisis.

Protected backups with controlled access

Immutable storage and separate access controls help protect recovery copies. We agree retention settings, permissions and tests as part of the backup design.

Recovery targets based on your business

We agree recovery-time and recovery-point targets for each critical system, then test the plan. Actual recovery depends on the incident, data volume, connectivity and available infrastructure.

FAQ

Frequently asked questions

Does Microsoft not back up our 365 data?

Microsoft 365 has retention, version history and recovery features; Microsoft also offers a separate Microsoft 365 Backup product. We review the features you have, their limits and your recovery requirements before recommending additional protection.

How often are backups taken?

Standard configuration is three times daily for servers and once daily for Microsoft 365 data. For clients with lower RPO requirements, we offer continuous replication with recovery points every 15 minutes.

Where is our backup data stored?

Primary backups are stored in UK-based data centres. Offsite replicas go to a geographically separate UK facility. For clients with data sovereignty requirements, all storage remains within the UK.

What does a disaster recovery test involve?

We simulate a complete site failure, spin up your environment from backups in our DRaaS platform, verify all applications and data are functional, and document the results including actual recovery times. Your team can participate or we handle it independently.

How quickly can you recover a single file versus an entire server?

A single-file restore is usually simpler than rebuilding a server, but neither has one universal recovery time. We agree targets after reviewing the systems and use documented restore tests to check what is achievable.
