Your data is the treasure of your effort and can be lost in an instant and in the simplest way: made a wrong click, or a virus/malware program with a system of faulty installation, or anything else.

If we are ordered to generate our data and we are in a directory tree in a logical manner, as in the example on the right, this is going to ease back later, we must also bear in mind that whatever the storage use: Hard Drive Backup tapes, floppy disks, CD-ROM, removable, … etc, which can fail and therefore it is ideal to use at least two alternatively use, or once again a the other. For example, we have a CD-RW for weeks and another pair for the odd.

There are many methods, but the last thing I will comment on is the best and the fact that I use:

Diskettes.
Dedicated partition.
Another computer.
Tape drive.
Removable classical systems.
Rewrite CD-RWs.
Burning CD-Rs.

1. Diskettes

Is the most traditionally used because it requires no additional hardware, but now has two serious drawbacks:

Unreliable
Floppies can be easily damaged.

Capacity
Capacity for the ridiculous file sizes of today: if you are dedicated to video editing, audio (including MPEG-3), photography, multimedia programming, or even something as simple as taking a backup of messages or mail, this option is probably not for you. Even if you do not do a lot of video editing, audio, etc, you may still run into the problem of needing too many floppies.

2. Dedicated partition / Hard Drive

This option is highly recommended since it is easily and cheaply storing the data in another physical location.

One problem with this is that a virus may be able to infect both of your hard disks if you are not careful. This is one reason why it is recommended to use multiple backup methods.

3. Another computer

In this case we have another team if we can make use of parallel or serial cables cross or network cards. You can even take pictures of hard drive / partitions using programs like Nero, or even Ghost linux commands like cat or dd (the latter is somewhat more complicated).

You can also connect to your friend who has a CD writer.

4. Removable systems

Here I include a removable hard disks, ZIP drives, Jazz, MO, SuperDisk, etc. allowing to use a few high capacity disks.

It is a good and fast back-up system but for the most hits is the cost of disks. If you compare costs per MB, you can back up between 20 and 100 times more data with a CD-R!

Another important point is that to transport information to another computer you will also need to have the same type of device on the 2nd computer. This be expensive in certain cases.

Another great solution in this category is USB flash drives. They are cheap and most computers have USB drives these days. If your computer does not have a USB drive, this is not a possible solution for you.

5. Tape drives

These were widely used in business especially in the past and are now in the catacombs of systems back-up. They are maddeningly slow system due to sequential access to information, instead of using random other devices.

6. CD-R

This is a simple and inexpensive way to make computer backups for a cheap price.

The biggest drawback is that when you make a copy of something you can not change and was therefore not appropriate for things that are updated a lot, eg the messages from your mail account.

Also costs to fill a CD-R complete data unless special cases such as video editing.

7. CD-R/CD-RW ReWriter

This is the ideal medium because it has the advantages of the CD-R without its only drawback, since you can also use CD-RW discs, which can be changed like a floppy disk. Disks are 3 or 4 times more expensive but if they are data is updated often you will need to use CD-RW as appossed to using a large number of CD-R disks.
