Based on your earlier comment, I dusted off the Fuji X App that I had on my iPhone — uploaded a fresh version, and figured out backup/restore with the Fuji X App.  And, as you say, IT WORKS.  I’m sure that I’ll keep several flavors of settings handy as you have done. But the reason that I really wanted to make backup/restore work is because I have, and shoot with, two X-T4s.  And it is very handy to have the same settings on both cameras.  Thanks to your emails, I have purged Fujifilm X Acquire from all my systems and now climbed in bed with Fuji X App.  Many thanks for your help.  And if sometime you find yourself resting, have a look at WWW.TOMCARROLLPHOTOGRAPHY.COM
Thanks again

Many thanks for your reply.  I do use a. MacBookPro with FUJIFILM X ACQUIRE.   And as you suggest, I have made sure that X ACQUIRE has access to all PHOTOS and FILES AND FOLDERS.  Also, all of my X-T4 and X100V and ACQUIRE software and firmware is up to date.  NO JOY.  All  I see is BACKUP DATA LOAD ERROR.  I have not tried iPhone backup — I’ll give that a try.  Fuji makes such beautiful cameras and such God-awful software.  Such a pity. Thanks for your input.

Many thanks for comments and suggestions.  I'll look into an alternative raw converter.  I would like to get this little perplexment sorted out.  Again, many thinks.  TC

Fuji needs to correct the long-standing firmware blunder in the X-T1, X-T2, and X-T3. Namely, the cameras reset the self-timer EACH time the cameras go to sleep or are turned off. This is a major pain for tripod shooters.  Fuji could easily correct this firmware blunder by providing a menu option for the self-timer to RESET or NO RESET (e.g., like Sony).  Come on, Fuji, let's fix this blunder.
