Macrium Reflect backup sessions very slow - since Window 10 upgrade?

First question would be how did you upgrade to Windows 2004? May seem irrelevant, but with all the known holds and bugs, it is quite relevant.

I let Windows Update do it. There were no other problems, except the minor ones I usually get with the 6-monthly upgrade,

It's good you are doing Macrium backups.

This is the first instance posted of this type of issue. Suggestion: Restore back to before the update, see if the backup times revert to prior timings. Then, check to see if the 2004 upgrade is still offered to you. If so, do the update again, there is always a chance you got a bad update, it happens. If the backup times again become excessive, go back to 1909. Unless you really need any of the "enhancements" in 2004, stay on 1909 for a while longer. 2004 is buggy right now with a lot of hard holds on it.

Maybe a short description of what you call the minor problems on upgrade would help.

Yes. Indeed it was offering it to me so I said Download. It then went and checked for updates again, re-offered it me so I went for it.

The minor issues I invariably get are:

• Epson Scan utility gets removed, quickly re-installed
• HP Laserjet 1320 loses knowledge of its installed options, in particular Duplex unit
• Start menu (I use Classic Start Menu) has to be tidied
• All the old Microsoft games get deleted (Minesweeper, Solitaire, Free Cell, etc.) get removed. I keep an early installation file tucked away

I think those are all. Nothing major, just a bit of post-update work to keep me awake.

Nothing serious at all with the "minors", I have a few, too.

Since it appeared to update without any obvious errors, the revert back and check routine should be tried. I doubt reinstalling Macrium will help, but you can try. If it's a paid version, make sure you have your key available. Deactivate the product key, then uninstall. Get a fresh copy of the installer from their site and install it, using your key.

Also remember that after every upgrade using the automatic update, there will be a Windows old recovery file added to the System disk, a partition image will thus be considerably larger than before, that could increase backup times, for at least ten days when the recovery file is deleted by windows

I uninstalled and re-installed Reflect. Time for a Data differential was still around 50 minutes.

Will now revert and see.

I'll also get my laptop out which I updated to 2004 a couple of days ago and see if that is similarly afflicted.

Good. I'll wait for what you find.............
