Backup-and-Restore-Using-SysRescueCD

Here is a simple script to backup a one-drive XS School Server. It assumes the standard layout of a /boot, /(root) and Library directories. This assumes an external USB drive mounted at /mnt/backup.

We will boot from SysRescCD 1.0.3 and run the backup from there.

The partimage program is able to create backups of each partition, which can be any of the following:

  • primary partition (/dev/sda1, sda2, sda3)
  • logical partition (/dev/sda5, sda6, sda7)
  • RAID partitions (/dev/md1, md2, md3)
  • LVM2 Logical Volumes (/dev/VolGroup00/LogVol00, etc.)
