    Chapter 21. Backup - an introduction

    Real men don't make backups - but they cry a lot. Which is what a woman editor once said to me.

    Yes, it is absolutely necessary to regularly make security copies. And if things are just organized a little, then everyone, independent of gender, can do it.

    Use several hard disks

    You need to have several hard disks available to make backups.

    You can use Zip drives, magnet tape units or CD/DVD burners to make security copies but the absolutely easiest way of doing it is to have several hard disks. You need precisely three hard disks with these and the right scripts, you can make a nearly 100 % safe system of backups.

    Fortunately hard disks are so cheap these days that it shouldn't be a problem having access to several hard disks. In my system, the first two hard disks are installed in the computer, where they perform as the C and the D drive respectively. The third disk stands on the desk in an external box, which can be switched on, when making backup.

    Figure 112. The external hard disk is connected to the computer with a USB cable. It is ideal for backup.

    The following description is the form for security copying, which I have used for many years. It is effective and easy to use only requires an organized system of folders with data, you know where to find, plus the afore-said three hard disks.

    Copying in two steps

    The absolutely most important thing when making backup is that you have a clearly defined folder system. You have to distinguish rigorously between temporary data and the type of data to be backed up. The last category includes text documents, photos, e-mails and much, much, much more. All of it has to be, without exception, placed in a predetermined folder structure, which is located in the folder D:\Texts.

    I have, however, two document folders on the D drive. The e-mail program uses the folder Mail for mail files. The files in this folder are copied as the first step into the folder Texts. This is an extra little security measure, which I am very pleased with.

    So the folder D:\Texts\Mail is, in fact, a security copy of the mail folder D:\Mail.

    The next step in the backup process is that all the contents from the folder D:\Texts are security copied in the folder C:\Textback. The C drive always contains, you see, backup of all user data:

    Figure 113.Daily backup.

    The advantage of making backups from the D drive to the C drive is that the two drives are on their own hard disk. This means that if one of the disks breaks down (and this happens more often than most people think), then there is always a copy of all the data. This form of copying ought to be done daily.

    But as both of the hard disks are installed in the same computer, there is a risk of the contents of them both being deleted if there is a virus attack. We have experienced this ourselves. This is why it is necessary for your security system to also have an external hard disk box, which is normally not connected to the computer. It is then protected from virus or other software-like attacks.
