i used this code to backup a directory to an ftpmirror -R /media/root/7CBAA4537758FCA/SAVE/DeesBootCD_SlipStreamed2/ /luksftpmnt/put-into-images-folder/DeesBootCD_SlipStreamed2and it worked well but some directories on original have small size but when copied they have no size.....the contents of these directories are correctly mirrored - all files same size, NO hidden files or symlinks that may have been corrupted.Original directory example:stat VCRTL/  File: 'VCRTL/'  Size: 4096        Blocks: 8          IO Block: 4096   directoryDevice: 811h/2065d  Inode: 44034       Links: 1Access: (0777/drwxrwxrwx)  Uid: (    0/    root)   Gid: (    0/    root)Access: 2015-07-26 04:34:06.897335000 +0000Modify: 2011-10-24 17:45:20.000000000 +0000Change: 2015-07-25 01:49:32.655572000 +0000 Birth: -Remote ftp directory example:stat VCRTL/  File: 'VCRTL/' Size: 0            Blocks: 0          IO Block: 4096   directoryDevice: 29h/41d Inode: 23451       Links: 1Access: (0777/drwxrwxrwx)  Uid: (    0/    root)   Gid: (    0/    root)Access: 2017-06-19 12:20:00.000000000 +0000Modify: 2017-06-19 12:20:00.000000000 +0000Change: 2017-06-19 12:20:00.000000000 +0000 Birth: -
