Hello
As i remember, this random named folder is used to store data gathered by follow symlink option.
Inside of it are only file named with numbers
However i can t find the data which link to theses files and due to the amount/size of these folders on several server, i am wondering if the purge is working properly
i did :
find /backuproot/servername/ -exec ls -lhd {} ; | grep b68xO+K9SCOF35cLk4Bf9Q
