01 / Risposta rapida
What is Office 365 backup, in brief
Office 365 (Microsoft 365) backup is a service that independently saves Exchange email, OneDrive files, SharePoint sites and Teams chats, beyond Microsoft's native retention limits. Delivered in the cloud with Veeam, it provides automated copies, granular restore even years later, and custom retention policies.
- Copies independent from the tenant, safe from ransomware and deleted accounts
- Granular restore of a single email, file, or an entire SharePoint site
- GDPR compliance with full audit logs and retention you control

03 / Native or Managed

Office 365 Backup: Protecting Your Business Data in the Cloud
Office 365 (Microsoft 365) backup is a service that independently saves Exchange email, OneDrive files, SharePoint sites and Teams chats, beyond Microsoft's native retention limits. TN Solutions delivers it as a managed cloud service built on Veeam Backup for Microsoft 365: automated copies, granular restore even years later, custom retention policies and full GDPR compliance.

Even though your data lives in the cloud, that doesn't mean it's safe. Microsoft guarantees the availability of the service, not the unlimited retention of your content: an accidental deletion, a compromised account or a ransomware attack can wipe out months of work. TN Solutions offers a professional Office 365 cloud backup service, built to guarantee business continuity, fast recovery and full control over your critical email, files and documents.
We protect Exchange Online mailboxes, SharePoint 365 documents, OneDrive for Business files and Teams conversations, ensuring granular restore of content with custom retention policies. Our system is designed for companies that want to go beyond the basic synchronization Microsoft offers natively. The service is part of TN Solutions' Data Recovery Center.
The Three Strengths of Managed Microsoft 365 Backup
Ease of management
Simplify Office 365 backup management with a cloud solution built for teams with no time to lose:
- initial setup handled entirely by us, operational from day one;
- backup policies per user, group or entire tenant;
- automation that cuts down on complexity and manual intervention;
- real-time notifications and periodic reports on backup status.
Flexible plans
Scalable plans that adapt to your company's size and budget:
- per-user fee, predictable with no surprises;
- compatible with all Microsoft 365 Business and Enterprise licenses;
- grow gradually: add mailboxes and services as you need them;
- no investment in dedicated hardware or infrastructure.
Maximum protection
Your data stays yours, protected and recoverable in every scenario:
- advanced encryption of data in transit and at rest;
- copies independent from Microsoft's infrastructure, safe from ransomware;
- GDPR compliance with full audit logs and documented retention;
- storage in certified EU data centers.
Office 365: How We Support You

Every Office 365 Disaster Recovery plan is designed to meet compliance standards (GDPR, ISO, HIPAA), with data copies stored in certified data centers. Unlike native tools, our solutions allow full or selective restoration, even months or years after deletion: a single email, an entire mailbox, or a SharePoint site exactly as it was before the incident.
We integrate advanced litigation hold features, scheduled backups, proactive monitoring and periodic disaster recovery tests, to make sure every file is genuinely recoverable.
We Are a Microsoft Partner

Choosing TN Solutions means protecting your Microsoft 365 data with professional tools such as Veeam Backup for Microsoft 365, configured to meet the specific needs of SMEs and larger organizations. We offer custom Office 365 cloud backup, compatible with every Microsoft 365 Business and Enterprise license.
We manage every environment with flexible policies, real-time notification systems and restore in a few clicks, without compromising user experience or service speed. As a Microsoft Partner, we also support companies on licensing, migration and adoption.
Who We Work With
We serve companies, professional firms and multi-site organizations that run on Office 365 in the cloud and need additional protection against human error, cyber threats and unexpected failures. Whether you manage 5 mailboxes or a tenant with hundreds of users, we design secure Office 365 backup solutions that integrate with your existing infrastructure.
Your entire Microsoft 365 environment — mail, files, sites, chat — protected by intelligent backup, fast restores and verified DR plans. And if your needs go beyond the Microsoft tenant, coverage extends with our enterprise Backup and Disaster Recovery service.
Business Continuity Best Practices: Testing, Retention and DR Updates
An effective disaster recovery strategy isn't just about backup — it also requires regular testing and continuous updates to the DR plan. TN Solutions applies BCDR (Business Continuity and Disaster Recovery) best practices to make sure Microsoft 365 data is always recoverable, even in the event of critical incidents or ransomware attacks.
We run periodic restore simulations to validate RPO/RTO and fine-tune configurations as your IT infrastructure evolves. Our systems also support advanced Retention Policy and Litigation Hold features, essential for meeting regulatory obligations and long-term retention of sensitive email and documents.

What Native Microsoft 365 Protection Doesn't Cover
Many companies discover the limits of native retention only when it's too late. Here are the typical cases where the recycle bin and standard policies fall short:
- deletions beyond retention limits: once retention windows expire (typically 30-93 days depending on the service), data can no longer be recovered;
- deleted accounts or deactivated licenses: a former employee's content can disappear along with their license;
- ransomware and sync: an infected client can spread encrypted files across OneDrive and SharePoint, overwriting healthy versions;
- errors or malicious admin actions: anyone with elevated privileges can empty even second-stage recycle bins;
- legal and audit needs: recovering a three-year-old email for litigation requires an independent archive, not a recycle bin.
TN Solutions' managed backup fills exactly these gaps, with copies stored outside the tenant and retention you control.


How We Activate the Service in Four Steps
- Tenant analysis: we review users, data volumes, licenses and existing policies (free, no obligation).

- Activation and first full backup: we configure Veeam Backup for Microsoft 365 and complete the initial copy with zero impact on users.

Frequently asked questions
Do I really need a backup for Office 365?
Yes. Microsoft is responsible for the availability of the service, not the complete protection of your content (shared responsibility model). A dedicated Office 365 backup protects against accidental deletion, ransomware attacks and human error, beyond the limits of the recycle bin and native retention.
What does cloud Office 365 backup include?
It covers email, calendars, contacts, OneDrive, SharePoint and Teams. It guarantees granular data recovery, versioning, long-term retention and secure access to copies even during a Microsoft service outage.
Is SharePoint Online backup included too?
Yes, SharePoint 365 backup is part of the advanced solution: it protects sites, document libraries, permissions and file versions, with selective restore and storage compliant with GDPR and company policy.
How much does Microsoft 365 backup cost?
The service runs on a monthly per-user fee, proportional to the number of mailboxes and services protected. After a free tenant analysis, we provide a clear quote with no hidden activation costs.
How long does it take to restore a mailbox or a file?
Granular restores (a single email, file or folder) typically take just a few minutes; full mailbox or site restores depend on data volume. Timelines are defined and verified through agreed tests, and in an emergency our support team guides the restore step by step alongside your IT contact.
