backup.sh is a simple shell script.

• rdiff-backup
• posix-sh
• awk

Is simply described in the script.

• exclude - define what places rdiff-backup must exclude
• o_opt - other options
• b_dir - original files destination
• d_dir - backup destination
• log - a directory for logs
• disc - partition needed to mount before making a backup

• configuration in external file
• (safe) parsing config file
• ebuild

Any suggestions?
