Bizarre Time Machine Issue with Music Media Folder

[drunkaviator]

Hi Folks, I can't seem to find any solution to this, but Time Machine is missing multiple folders from my Music Media folder - there's about a 15GB discrepancy between my Mac's drive and the TM backup. I've looked through and entire artist folders are missing, but it's sporadic. Has anyone else experienced this and could offer any help? It occurs on both my TM drives. Thank you kindly ☺️

Are there any special characters or anything like that?

No, it's fairly random, just a bunch of artists from F through to J. In the end I deleted and reimported those songs, and it started backing up again. Still a complete mystery...

I'm on a vertical learning curve right now...TM uses the date/time of the file to know whether to back it up. I wonder if it ignores files dated in the future?

I've checked the original files that I dropped manually onto another drive before this problem occurred. They are definitely all dated correctly, and in the past. So it's not that. Hmm

Saw something similar in November with 25.1.0. That release "lost" some files under Music but, luckily, only a handful podcast related files I kept under there.

Seem to recall some other files got toasted by that release as well but I had a manual backup that I was able to go back to and recover the handful of files.
