app-backup/mirror-backup

This is a backup script generator for backing up my system to external USB drives.

Introduction

The main task

Allow for declarative description of the backup tasks by describing which source directories are to be backed up
Check for common errors.
Generate a shell script to to the job.

Other Tasks are

Check for duplicate backups actions.
Verifying that the source and destination paths exists and are mount points when that's necessary.
Outputting a very user-readable shell script that can be easily checked before running backup.

Running

Edit the configuration (currently the backup plan records inside app-data.rkt
Run the program

racket mirror-backup.rkt

2.1. That creates the program: *mirror-backup.sh*

Examining the shell script.
Run the script:

sh mirror-backup.sh

There is a Makefile in the sources directory. Running

make test will generate the shell script and run it.

Caveats

Running this script requires superuser privileges. At least that is the intention. It cat work for anyone who has permission to write in the target paths.
Some knowledge of Scheme could be helpful. It is easy for a non Schemer to hose things up.
Requires Racket pagkage "Rebellion":

raco install -i --auto rebellion

Dreams

Eventually, the configuration my be separated from the source code and converted into a YAML config file. From there, even a GUI is possible for the purposes of configuring and ruining the backup.
