Options
Archival
When tar is executed as root, the file permissions and owner are preserved.
-p
Preserve permissions, default when the root executes the command.
-s
Preserve order (same order). Sort names to extract to match archive.
Archive
Archive maintaining the user IDs and file permissions:
tar -cvspf .../archive.tar *
Note that the name of the archive file to be created must immediately follow -f, without any interceding parameters.
Restoration
Restore preserving the user ID and file permissions (if done as root, the behavior is implicit)
tar -xvspf .../archive.tar
