It is, actually. Windows 10 and 11, at least the non-corporate versions, have multiple, endless reminders about how important it is to activate Windows Backup. The nags will pop up after most Windows Updates but also at various random times. Sometimes they’re formulated as “let’s finish setting up backup for you” or “this PC is not fully configured, here are the next steps” and then you have to find the link in a corner that says “not now”. Sometimes it’s a nag on the login screen, before you type in your password or PIN. Sometimes it’s a notification in the Start Menu.
The wording is misleading, talking about Backup when it’s actually OneDrive. The ultimate goal is to move all your important files to OneDrive and then, when you run out or room (because the default OneDrive has only a few gigabytes of capacity), start charging you to store your own data.
And since most people log onto Windows using a cloud account, once they accept, there’s no need for Microsoft to ask for credentials. They just connect to your default OneDrive and get busy backing up (backuppping?).
It wouldn’t be so bad if it weren’t broken. To make OneDrive work, your files are moved to the OneDrive folder. For some programs like older versions of Outlook (from Microsoft!), that move just breaks everything.
And then, in many cases, some of the content gets removed from the local disk and turned into web links, some of which are broken. It’s been a problem for almost a year, and now Microsoft is doing a Trump and claiming it was meant to behave like this all along.
ETA: At work, we use a corporate version of OneDrive and SharePoint and Teams and Office 365 (now called Copilot 365 I think) continuously since 2020, and it works wonderfully well. We have very little paper, very few physical servers with documents, it’s all in the cloud. Our laptops automatically move things back and forth from the hard disk to the cloud to prevent the disk from getting full (Windows “Storage Sense”). So I know it can work very well when it wants to. But the non-corporate OneDrive / Backup is a hot mess, and a trap.
