Pourquoi vos données dans le cloud ont besoin d’un backup ?

03 January 2026

Emails, video conferences, online storage... The cloud has transformed business collaboration. But one key question remains: are your data really protected?

The myth of total security

Les grands fournisseurs comme Microsoft, Amazon ou Google assurent la disponibilité de leurs infrastructures et la redondance des données pour éviter les pertes liées à une panne matérielle.

However, protection against employee negligence or malice, cyberattacks, or accidental deletion remains your responsibility. Whether you use a virtual server or services such as Microsoft 365, an additional backup is essential.

Why is backup crucial?

  • Ransomware, corruption, or accidental deletion: native restores (SharePoint, Exchange) are limited and often complex.

  • Retention periods included in Microsoft 365 services:

    • SharePoint / OneDrive: deleted files can be restored for 90 days.

    • Exchange Online: emails are retained for 14 to 30 days.

    • User accounts: data is deleted after 30 days.

Beyond these periods, no recovery is possible without a backup. An automated solution allows you to restore your critical data, even several months after an incident.

Why do your cloud data need to be backed up?

For optimal protection :

  • Opt for an automated backup solution, ideally in the cloud.

  • Choose a reliable provider with flexible options (duration, volume, frequency).

  • Costs are generally based on your actual consumption.

In the event of a ransomware attack or accidental deletion, a backup ensures that your files or servers can be quickly restored.
