--create and --file are needlessly verbose, c and f suffice. --atime-preserve is unnecessary since that is the default behavior. -p is only meaningful when extracting. -P is bad practice, never use absolute paths in tar archives. writing the tar archive into the same path being archived will depending on tar implementation try to archive the tar file.
