Passwords and back up

The first elementary safety measures of the data are:

Password protection of the machine which lodges them . If several users use the same machine, it will be judicious to create several different accounts. If possible, it is necessary to use the passwords BIOS of the machines, which present a higher degree of safety than the traditional passwords (those of Windows are easily contournables in general). Once again: no password is inviolable. But to put some is already a first barrier.

Not to use the passwords of the applications to protect from the data, the systems are often not very reliable and it is not wise to be really believed in the shelter without being it. For really protecting from the data they should be quantified. Or one leaves them in light.

To carry out safeguards regularly. The support could be diskettes (attention however with their deterioration), CD-ROMS or possibly a removable hard disk. A detailed attention must be paid to the protection of the safeguards themselves: no interest indeed to make safe its machine and its data well if safeguards "in light" are a little everywhere. Lastly, in the majority of the cases it is judicious to create two partitions on its hard disk: one (C: \ for example) which will contain the operating system (OS), and the other (D: \ for example, "/home" under Linux) which will contain its personal data. The interest of such a partition is that in the event of serious problem on the operating system, the data are less likely to undergo the consequences of them. If there is the possibility of having two physically distinct hard disks, it is still better.
