There are many ways to minimise loss of data:
 Periodically
backup your data onto some other media such as hard disk drive, CD/DVD disc,
ZIP disk, streamer tape, floppy disk and so on;
(Occasionally check backups to see if they can be restored.)- Backup
your system partition using a partition backup program (Such as:
Active Partition Recovery);
- Don't
save your data on the same partition where your operating system and programs
are installed - it will be much easier to restore/reinstall operating system
without touching your data;
- Use
NTFS/NTFS5 file system instead of FAT16/32 if your operating system is windows
NT4/XP/.NET;
- Use a
reliable RAID;
- Use an
antiviral protection;
- Use a
firewall to protect your data from unwanted access from the Internet or
network;
- Use
quality hardware: motherboard, memory, hard disk controller, hard disk cable,
hard disk drive, power supply. Do not over-clock the hardware;
- Never
switch off your computer with the operating system loaded by using the power
button or reset button;
- Don't
forget, you will not be able to read your data after you change your password
or reinstall/upgrade operating system.
Data Backup:
The primary rule is to backup your data. The more often you backup your data,
the smaller the chances you will lose your valuable data.
The following are examples of data backup techniques:
- Copy your
data to another partition of the same hard drive (less secure, because you can
lose both copies due to a of a hard drive crash);
- Copy your
data to another hard drive in the same computer (more secure, but you still can
lose both copies due to a of the computer crash);
- Copy your
data to another computer (secure enough, but there is still a possibility to
lose your data when both computers are in the same room);
- Copy your
data to removable media, such as removable hard drive, CD/DVD disc, ZIP
disk(s), streamer tape, floppy disk and so on. This media, once removed from
your computer, will give you the most security. (Check backups to ensure they
can be restored)
Data Encryption:
Data encryption is used only to protect the data from reading and copying
(stealing) but will not protect it from being lost.
