Correct. And as stated in the README file that comes with 7-zip:
CAUTION :
---------
- FIRST : DO NOT USE the 7-zip format for backup purpose on Linux/Unix because :
- 7-zip does not store the owner/group of the file
On Linux/Unix, in order to backup directories you must use tar !
to backup a directory : tar cf - directory | 7za a -si directory.tar.7z
to restore your backup : 7za x -so directory.tar.7z | tar xf -
- if you want to send files and directories (not the owner of file)
to others Unix/MacOS/Windows users, you can use the 7-zip format.
example : 7za a directory.7z directory
do not use "-r" because this flag does not do what you think
do not use directory/* because of ".*" files
(example : "directory/*" does not match "directory/.profile")
