 Backup Files
 ============
 
    Normally, `patch' creates a backup file if the patch does not
 exactly match the original input file, because in that case the
 original data might not be recovered if you undo the patch with `patch
 -R' ( Reversed Patches).  However, when conforming to POSIX,
 `patch' does not create backup files by default.   patch and
 POSIX.
 
    The `-b' or `--backup' option causes `patch' to make a backup file
 regardless of whether the patch matches the original input.  The
 `--backup-if-mismatch' option causes `patch' to create backup files for
 mismatches files; this is the default when not conforming to POSIX.  The
 `--no-backup-if-mismatch' option causes `patch' to not create backup
 files, even for mismatched patches; this is the default when conforming
 to POSIX.
 
    When backing up a file that does not exist, an empty, unreadable
 backup file is created as a placeholder to represent the nonexistent
 file.
