Simplyfied CD Backup for Linux

Purpose:

Formats:


Hardware requirements:

A CD recorder suitable for cdrecord ( see list of drives ) As far as i know, it should be a real SCSI recorder although there are tricks to make ATAPIs look like SCSI.

Software requirements (available on all Linux systems, i guess):

/bin/sh
compatible to GNU Bourne-Again SHell (bash).
including usual programs like: cat, date, du, echo, ls, ...
see hints for working around shell compatibility problems
afio
archiver program (for system backups)
bc
calculator language (only if you employ the locking protocol)

GPL software included (does not interfere with existing software) :
static compiled. Opportunity to download cdrecord-1.6.tar.gz below

cdrecord
transfers data to CD
mkisofs
generates ISO9660 file systems which are accessible with nearly any modern system

This program system has been tested on Intel/AMD Linux systems only.
Ports to other usable systems are appreciated.


Special features:

Commands:

The idea is to use afio archives for the system directories and those where symbolic links are important. All normal user data should be backuped as ISO9660 for fast and easy access.

scdbackup_sys
backup of system directories as afio archives. (not mountable)
Example:
scdbackup_sys
scdbackup_home
backup of the user's $HOME directory. ISO9660. (mountable)
Example:
scdbackup_home
See a sample run.
scdbackup
command for defining own backup collections and for spontaneous data copies. ISO9660. (mountable)
Example:
scdbackup /home /home2=/usr/home -not /home/guest
Backup /home and /usr/home . But use /home2 on CD as name for /usr/home and omit subdir /home/guest
scdbackup_afio
like scdbackup but using afio archives rather than ISO9660 file systems. (not mountable)
Each of the commands examines the backup data, plans their distribution over the CDs and then prompts the user to insert CDs until all are done.
