Backup forum

Do you have continuous backup enabled?

I'm wondering if its hoovering up changes during the day so there's nothing to backup at the scheduled time.

Do you have multiple user accounts on your Windows machine?

There is a check box in the IDrive settings "allow IDrive only for current profile", maybe it doesn't have permissions to backup your profile "Family" while its authenticated as another user.

I would suggest this box should not be checked if you want IDrive to backup other profiles (I've never needed to experiment with it myself).

Only the admin account (which we almost never use).  I thought it might be some conflict with Windows Defender too but I've not really found any evidence for that.  My Windows setup is very vanilla.  I can't understand why I would be having this problem and no one else is.  Is it unusual to use continuous backup with scheduled backups?  I could turn one or the other off I suppose.  I'm also using the account to backup several phones and a remote Windows PC.  I wonder if that is a factor here.

I use continuous backup and Windows Defender, albeit on Windows 7, and I haven't had problems as bad as this.

Occasionally I get a message like:

Something has gone wrong with your last backup from the computer "****". For further investigation, we request you to log in to your desktop application and send the error report using "Send Error Report" feature.

but it'll usually be ok next backup, so I ignore it.

Not sure why you're having more severe problems.

Have you looked in the Windows Application and Systems logs for clues?

I'm not sure what else to suggest.

If you go into the Restore tab on the IDrive client, do you see the latest versions of your files?

Is it picking up changed and new files? If Continuous Data Protection is switched on, it should back up files as soon as they're modified or created (or you can choose to delay it).

I'm posting an update just in case this helps someone else.  I just noticed in the release notes for the latest Windows 10 update that it "Addresses a rare issue that causes Windows Defender Advanced Threat Protection (ATP) to temporarily prevent other processes from accessing files."  Perhaps that's a factor here.  IDrive support asked for an error log then asked that I contact them interactively.  Haven't gotten around to that yet.  It hasn't failed for a week or two now.
