In any case, history has conclusively demonstrated that it is
extraordinarily important to back up your resources residing
within the Microsoft 365 cloud – especially if you are using
Teams. In fact, there are at least six different reasons why
Microsoft 365 backups are so important.
Reason 1: Accidental Deletion
The first reason why it is so important to back up Microsoft 365
is that users can accidentally delete data that they need. For
example, a Teams user might accidentally delete an important
contact or a file that they need. We've all seen this sort of thing
happen in on-premises environments, and it can happen just as
easily in the cloud. Similarly, a user might overwrite good data
with bad data. It happens. And when it does, you need a way of
getting the user's data back.
Even though I am ashamed to admit it, I
accidentally over-wrote good data with bad
data just last week. I was working on a
different book, and accidentally saved my
notes in place of the chapter that I was
working on. Since I had just written the
chapter, it had not yet been backed up and I
had to rewrite it. Needless to say, that wasn't
much fun. As painful as the incident might've
been, it underscores the importance of
backing up data as a way of protecting it
against mistake-related losses.
The good news is that Microsoft does give you a way of getting
back data that was deleted accidentally. If a user accidentally
deletes a file from within OneDrive, they may be able to use
the OneDrive Recycle Bin to get their file back. Similarly, if a
user accidentally deletes an email message that they need,
they can recover it from the Deleted Items folder.
