Prerequisites
Programs and System
We use system with SuSE 10.1 and the K3B disk burning progam. The reasons are:
- You can easy write scripts for k3b
- SuSE is a well known and easy to configure distribution
For pack the date we use tar and gzip.
Backup media
Backup media are dvd RAM, because they are the only media with assure long time support for your data AND assure that the data is written correctly to the medium. Normal dvd media types don't assure that.
The media MUST be formatted as an inkremental media. Otherwise it is not possible to burn multisession dvds!
To do
Do a real incremental backup of your data within the tar files.
Make an archive directory
To save any data you shoulf have a directory appart from your common dokuments. This directory will be burned to the disk entirely. The K3B program than assures that any new data is not burned twice to the disk.
K3b script
#!/bin/bash
