If You Use Office 365, Do You Still Need to Backup Your Data?
The short answer is, Yes.
Microsoft Office 365 is a cloud-based office software suite designed to enable modern teams. It has location redundancy, meaning that your data is backed up over multiple data banks so that if one goes down, your team can keep working. It also saves your data and keeps deleted files for one to three months. Files you keep active on Office 365 are extremely robust. Even two major natural disasters couldn't take your data down. You also may have noticed that Office 365 appears to back everything up to the clouds so that no data is lost, even with interrupted connections and new locations.
But even with Microsoft 365's cloud features, you still need to backup your data with private methods. Office 365 may be on the cloud, but it cannot (and does not) replace the duty of responsible and regular backups.
