Disaster Recovery for Linux
There is no bootable Linux system on HDD in a disaster situation; therefore it is always a good idea to backup the bootable Linux system on removable media for example on floppy disks. For example if the hard disk fails, or if an important file is accidentally deleted. No matter what the cause is some recovery procedures will be needed.
The first step to recover from a disaster is to make a custom boot disk. It is not sufficient to just copy the standard boot disk image from the Linux cd rom because it will not necessarily have all the Kernal support configured. First log into the root shell session by using the cd / command and inserting a floppy disk. Then examine the /etc/lilo.conf to find the Kernal identity and use the mkbootdisk command and device /dev/fd0 with the string, example 2.2.5-15, found in the /etc/lilo.conf.
