I upload to Lightroom, note that the images have all been uploaded,

it set to back-up each time it's closed.

do you have it set to copy that 'backup' to a different drive not in
the computer?

I have two external drives, and they are where the back-ups go.

you didn't say where it goes. you just said it backs up.

do you expect everyone to know how many external drives you have and
how you've configured lightroom?

if not, then it's not a backup. it's just wasting time and space on
your drive.

more importantly, lightroom does not back up the photos, which is the
important part. the catalog can be recreated but the photos almost
always cannot.

Gee. That's news. What direction does the sun come up in the
morning?

what difference does it make? your head is so far up your ass you won't
ever see the sun.

Images are uploaded to a file on D:, and the D: drive is backed up to
an external drive every night.

leaving you vulnerable for as much as 23 hours.

Sure. But so what?

the 'so what' is when (not if) your drive fails, you will lose up to 23
hours of stuff.

I've stated many times that I'm not a high volume
photographer. What is vulnerable is the last upload, and that's
usually 5 or 10 keepers on a good day. During the grandson's football
and baseball season, the volume increases but I usually don't get
around to formatting the card until the next time I shoot.

if it's not important enough to back up then why bother taking the
photos in the first place?

If it's really important set of images (which it rarely is) I'll burn
a disk or stick them on a thumb drive right after uploading. I can't
remember the last time I did this, though.

in other words, nothing you shoot is important.

no surprise there.
