I’m making an attempt to backup the /Consumer/user01/Library utilizing rsync (by way of the linux-timemachine wrapper https://github.com/cytopia/linux-timemachine) to an exterior exhausting drive Volumes/name_of_backup logged in as user01. Through the backup I get the next error message

rsync warning: some recordsdata vanished earlier than they may very well be transferred (code 24) at /System/Volumes/Knowledge/SWE/macOS/BuildRoots/220e8a1b79/Library/Caches/com.apple.xbs/Sources/rsync/rsync-55/rsync/most important.c(996) [sender=2.6.9]

What I do not perceive is that the file /System/Volumes/Knowledge/SWE/macOS/BuildRoots/220e8a1b79/Library/Caches/com.apple.xbs/Sources/rsync/rsync-55/rsync/most important.c shouldn’t be even positioned within the listing that I’m making an attempt to backup (particularly /Consumer/user01/Library). So why does this error seems?
