User error and deletion
Deleted emails, lost files, or overwritten content can only be recovered within narrow time windows in native Microsoft 365®. After that, the data is permanently lost.

Cloud2Cloud SaaS Backup - full steam toward security
Your data isn't automatically safe in the cloud - and the risk sits with you.
The overlooked risk
Your data isn't automatically safe in the cloud - and the risk sits with you.
Many companies rely on Microsoft 365® or other cloud providers and assume their data is fully protected. Data loss isn't an IT problem - it's a business risk.
Ransomware and cyberattacks
Ransomware doesn't just encrypt local systems - it increasingly hits cloud environments too. Without an independent backup, your Microsoft 365® data is at risk too.
Limited recovery
Microsoft® secures the infrastructure - but not your data completely. Retention periods are limited, recovery options restricted. Your company bears the residual risk.
Dependency and the CLOUD Act
US hyperscalers are subject to the CLOUD Act, at the expense of your sovereignty. Without an independent backup, you lose control over your data in an emergency.
The reality: deleted emails, lost files, or manipulated content can often only be partially recovered from Microsoft 365®, or not at all. The risk sits with the company - not the provider. Without an independent backup, you lose control over your data in an emergency.

Our Cloud2Cloud Backup solution is used by organizations where data sovereignty is business-critical - from critical infrastructure operators to the financial sector to public authorities.
Act now - here's why
Data volumes are growing, attacks are increasing - independent backup is no longer optional.
Four developments make independent cloud backup a strategic necessity.
Rapidly rising cyberattacks
Cyberattacks on cloud environments keep increasing and hit companies more precisely than ever. Ransomware attacks on Microsoft 365® are no longer the exception.
Possible US access to your data due to the CLOUD Act
The US CLOUD Act requires American companies to hand over data on request. Microsoft® and Google® are affected - regardless of where the data is stored.
Tightened regulation through NIS2
NIS2 and GDPR raise the requirements for data protection and business continuity. Companies must prove that critical data can be recovered at all times.
Geopolitical risks
Rising geopolitical tensions, economic uncertainty, and natural events additionally threaten the availability of data and cloud infrastructure.
Anyone without an independent backup today risks the loss of business-critical data tomorrow. Data loss isn't an IT problem - it endangers business continuity, compliance, and the stability of your entire company.
Frequently asked questions about Cloud2Cloud Backup and hyperscalers
What is Cloud2Cloud Backup?
Cloud2Cloud Backup is an independent data backup outside the original SaaS platform. It backs up data from Microsoft 365®, Exchange Online®, Teams®, SharePoint®, or Google Workspace® into a fully separate, independent system - so your data remains completely recoverable at all times, even after deletion, manipulation, or ransomware attacks. groupios stores these backups in a GDPR-compliant way in German or European data centers.
Why do I need an additional backup for Microsoft 365®?
Microsoft 365® secures the availability of its infrastructure - but not your data in the classic sense. Deleted emails, lost files, or manipulated content can often only be partially recovered, or not at all. Retention periods are limited, and the risk of data loss sits with the company, not with Microsoft®. An independent Cloud2Cloud Backup consistently closes this gap.
Is my data in Microsoft 365® automatically backed up?
No. Microsoft® protects the infrastructure, but only offers limited retention and recovery options. Without a separate backup solution, there’s a risk that data is permanently lost after retention periods expire or during certain incidents. groupios’s Cloud2Cloud solution provides genuine data control and long-term availability - independent of Microsoft®.
What does the 3-2-1-0 principle mean for data backup?
The 3-2-1-0 principle is the proven method for secure data backup: 3 copies of your data, on 2 different systems, with 1 copy independent of the original environment (offsite), and 0 errors - meaning regular integrity checks that guarantee recoverability in an emergency. groupios consistently implements this principle - including automatic verification of every backup.
How does Cloud2Cloud Backup protect against ransomware?
groupios protects through three mechanisms: first, backups are fully separated from the production environment - ransomware can’t spread to the backup. Second, immutable backups are used - stored data can’t be subsequently encrypted or deleted. Third, versioning lets you roll back to a clean state from before the attack.
What advantages does groupios offer over US hyperscaler solutions?
groupios Cloud2Cloud Backup runs on German and European infrastructure - fully GDPR-compliant and with no dependency on the US CLOUD Act. Your data is subject to clear German and European law. Unlike US hyperscalers, no foreign government has access to your backup data. That creates genuine digital sovereignty - especially important for public authorities, critical infrastructure operators, and regulated industries.
Which SaaS services can groupios back up?
groupios backs up all relevant SaaS services: Exchange Online®, OneDrive®, Microsoft® Teams®, SharePoint®, Gmail®, and Google Drive®. The solution integrates seamlessly with no extra devices or local installations and scales for small businesses, mid-sized companies, and enterprise organizations.
