Disaster Recovery for Linux There is no boot able Linux system on HDD in a disaster situation; therefore it is always a good idea to backup the boot able 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 command and device /dev / fd 0 with the string, example 2. 2. 5-15, found in the /etc / lilo . conf.
The una me -a command can be used to display the Kernal version. After the successful completion of that step eject the disk and write protect it. Another way to recover from a disaster is to make a rescue disk. The rescue disk is taken from the image in the linux cd rom. It is not like the custom boot disk where an examination of the /etc / lilo . conf is done.
What makes the boot disk created for the system valuable is that it contains the special drivers, such as SCSI drivers, that may be required to boot the system. Another alternative to recover from a disaster is to create a Tom’s Root Boot Diskette. The distribution may be done on the internet: A complete Linux system on a single diskette. To create the diskette set the browser to web and download the latest version. To prepare the emergency boot disk, place the zipped tar file into a directory such as /us / local /s rc and follow the install procedures. The tar file is a versatile archiving utility that is not limited to strictly tape backup.
The Term Paper on Linux Operating Systems Proposal
To make our company great we should choose to incorporate Linux with all of our desktop and servers. For our desktop hosts I suggest that we should choose Ubuntu Linux. I believe that this Operating system is dependable and should last the test of time. Users whom are familiar with Windows should feel comfortable with Ubuntu and if the change seems too drastic for some users the option to go with ...
TAR files can be stored locally as files, and sent over networks as a method of back up. The package squeezes an amazing number of Linux utilities onto a single 1. 7 MB floppy by using high compression. Conclusion No matter what method used to back up the Linux system it is very important to take caution when dealing with Kernal con fig files.
Always use the man command before using a command so the right syntax and option are used so that an important file isn’t deleted. web.
