ChronoSync backup error -54 for DEVONthink metadata

Hi, a ChronoSync backup reported 172 x error -54 (I think that’s “unknown error”).

The majority of files are in

/System/Volumes/Data/Users/user/Library/Developer/Xcode/DocumentationCache/

and

/System/Volumes/Data/Users/user/Library/Developer/Xcode/DocumentationIndex/

and their names all contain index.spotlightV3, so it’s probably related to Spotlight. I can probably exclude these folders from backups without breaking something (please let me know if that’s not the case).

But this error is also reported for these files …

No idea why ChronoSync can’t handle these files but that’s just the data for the Spotlight index, see File > Database Properties. No need to copy this.

It never threw this error in the past (for DEVONthink Spotlight metadat, neither on the old mac nor on the new :thinking: I’ll exclude the folder. Thanks!
