   Backup aborted! - Unable to read from disk - Error Code 21 - The device is not ready.

Not sure what to do next?

Thanks.

This KB article looks relevant to the first one. Which aside from a different backup software running can sometimes be down to Windows Update, or some other installer making a snapshot/restore point at the time Macrium also tries.  Which in the case where it's WU is purely an unlucky coincidence of timing.

The second is harder to know what to say about without more info about what was being backed up, however, it looks like something preventing the source being read.

When you see VSS errors, it's often helpful to review the VSS log, which is separate from the main job log.  It may contain more information.  But based on that error, you might be able to fix that with a simple restart.

Thanks jphughan,

Seeing as today is Monday (at least in the US), I'm not sure what day the Tuesday log refers to, but did you try just restarting?

We're downunder, so Tuesday already here
Restarting the computer?

Yes, restarting the computer.  And if that doesn't work, try the Fix VSS Problems utility built into Reflect, found under the Other Tasks menu.

Just spoken to the user, and after the Monday error, she restarted with all the windows updates installing.

Which is what Beardy said, thank you.

So I'll need to look at the second error now, I'll check Macrium and see if there are any updates available.

Ran Macrium upgrade from 7.2 to 7.3, then ran Full backup which went well.

Lets see what happens today during scheduled backup.
