Office 365 is Microsoft‘s office suite, the most popular and used by all types of people, from home users to professionals. This package is made up of the applications Word, Excel, PowerPoint, Outlook, Publisher and Access, which will be of great help to us for all kinds of tasks Its main advantage is that we can access all programs in real time from any device with access to Internet.
In the event that any problem occurs within the platform, Microsoft takes care that our data is not at risk to avoid any loss of it, so that it is fully protected. Apart from the recovery options that Office 365 can offer us, it is highly recommended to make a backup on our own .

This is because, although Microsoft protects us against loss of service due to hardware infrastructure failures and offers 30 days of recovery for the recycle bin in Outlook, there are other cases that are our responsibility . Therefore, we are going to see three fundamental reasons why we must carry out a backup.
Prevent accidental deletion
Human error is always present and no user is safe from accidental deletion of documents or emails that we may need later.
It is true that with the recycle bin we have 30 days to recover those deleted items, it is what is known as a soft deletion . The problem comes when we realize that we have deleted an important element, once that time has passed. In the same way, there is also hard deletion , which happens when an element has been tagged to be removed from the base. In any of the cases, if we do not have a backup we will have lost the deleted item.

External threats such as viruses or malware
Office 365 offers its users various protections against external threats such as viruses, malware, and ransomware. Since there is no perfect protection, every precaution in this regard is insufficient to avoid putting the privacy and security of our internal data at risk.
And it is that on the Internet we are exposed to any threat in emails, within the attached files. Or also in any file that we download from an unreliable source that can end up infecting our data. That is why it is advisable to make a backup periodically in the event of any inconvenience of this type that may arise.

Configuration or synchronization errors
Another reason why it is advisable to make a backup is due to the possibility of configuration or synchronization errors in our Office 365 account. A simple configuration error can lead to possible synchronization errors. This can cause our data to be destroyed or overwritten , being irretrievably deleted.
