I cloned a Time Machine backup folder
Backups.backupdb from one volume to another following Apple's instructions. The contents of both folders look very similar (same amount of files, same file size, etc), so I assume the cloning worked well.
However, some files have different permissions listed when displayed with
ls -l: A file
Info.plist on the original volume shows like
-rw-r--r--@ 1 extra staff 13512 Jan 7 2015 Info.plist
while on the cloned volume it shows like
-rw-r--r--+ 1 extra staff 13512 Jan 7 2015 Info.plist
According to the macOS
ls man page (I'm using OSX El Capitan) this means that the original (with
@ after the standard permission) has "extended attributes", while the clone (with
+ after the standard permission) has "extended security information". Clearly something is different.
What went wrong and how can I make a clone without these differences?
