    As the sfc help says /OFFLOGFILE is for offline repair only.

    Hi, just wondering where you got the offlogfile parameter from...
    I got /OFFLOGFILE from running the command SFC on my Windows 10 PRO Version 1809 build 17763.55

    Thanks, as I noted above that confirms it has been added since build 1709 (which I'm staying with for now to avoid issues with both 1803 and 1809).

    I'm all set now, but a little history might be interesting.
    I bought a PC of my configuration in 2012; the C: drive was a 128GB OCZ Vertex SSD.
    Around 2015, the system failed to boot, and the shop where I bought it replaced the drive and installed Windows XP.
    This SSD reached end-of-life and I replaced it myself.
    December 2017, the system wouldn't boot again. The local PC repairman checked the drive; it seemed OK. So he reinstalled Windows 10 (by now).
    September 2018, and the SSD failed catastrophically. Local man installed 480MB SSD and put Win XP back on (it was on the PC's label)
    October 2018 local PC man put me back to Windows 10 by my request.

    I'm on my fourth SSD boot drive in 6 years. I was always a backup freak (I have 4 levels of backup), but the backups couldn't restore the OS.
    So, I now have daily backups of the SSD drive (Acronis True Image). I use the Kingston SSD health checker every day.
    And I decided to run SFC /VERIFYONLY every day. This is where /OFFLOGFILE appeared.

    Since I cannot get /OFFLOGFILE to work, I'm using redirection of SFC output to a file, then running a script to scan said file for unpleasant surprises.

    I suspect that all this checking of the SSD might be putting extra load on it, not helping its lifetime. Also, the PC runs 24 hours (the backups run all night to a friends garage server about 15 miles away)

    That won't help lifetime in terms of powered on time- although there are plenty of discussions about the lifetime of SSDs vs no. of reads and writes suggesting that normally that should not be a factor.

    Great idea to have remote backup, but I'm wondering as to the basis- presumably connection speed is a limitation. Hopefully you're at least using incremental disk imaging to reduce the size of the image rather than creating a new base image each time.

    A local backup to external USB3 disk of my 50% used 256Gb SSD, differential disk image, takes under 13 mins typically.

    You might consider changing the regime- e.g. local backups most days, upload once a week using disk imaging.

    Add to that another backup program which deals with critical data rather than the OS, and have that uploaded (would be much smaller, faster).

    You should check the PSU on your computer, consider replacing it. No way you should go through 4 SSDs in 6 years. I'm still using the original 120GB SSD I bought 5 years ago only now it's running in my older laptop. My 250GB SSD is in my primary laptop, moved from my Desktop which I upgraded to a 500GB SSD earlier this year. All are in excellent health with not a single error.

    My Desktop runs 24/7, same as yours and has done so for since I bought it 5 years ago.
