Editing Backing-up your home directory
== Zero level backup == You should periodically (once a month ?) make a full backup of your area (what is called a zero-level backup). This is easy : <code> rm ~/.tar tar -g ~/.tar -zcvf /tmp/myarea_Date.tar.gz /home/myself cd /tmp ls -alFh myarea_Date.tar.gz WriteCD myarea_Date.tar.gz mount /mnt/cdrom/ diff /mnt/cdrom/myarea_Date.tar.gz ./myarea_Date.tar.gz [if diff fails, your backup failed] umount /mnt/cdrom/ rm myarea_Date.tar.gz </code> where 'myself' is your user name, 'Date' is the date (in the form 05Jun2005), and the /ls/ command is used to allow you to confirm that your tar file is less than 700 MB. == Incremental backups == At the end of each working day, do an incremental backup : <code> tar -g ~/.tar -zcvf /tmp/Incremental_Date.tar.gz /home/myself cd /tmp ls -alFh Incremental_Date.tar.gz WriteCD Incremental_Date.tar.gz mount /mnt/cdrom/ diff /mnt/cdrom/Incremental_Date.tar.gz ./Incremental_Date.tar.gz umount /mnt/cdrom/ rm Incremental_Date.tar.gz </code> Depending on how active (disk-wise) you've been, the incremental backups should be fairly small files (and you can fit plenty of them in one CD).
