Rsync-linux backup script

Compile as script

The basic form of this script is from the rsync website. In fact, there is only one command:

Rsync-force-ignore-errors-delete-excluded-exclude-from = exclude_file-backup-dir = 'date + % Y-% m-% d'-av

Key parameters are:

-Backup: backup files before Overwriting
-Backup-dir = 'date + % Y-% m-% d': Creates a backup directory for the backup file, which looks like: 2002-08-15
-Av: archive mode and verbose mode.
