Protection of data whatewer you do is a difficult task.
If you don't create anything it remain simple, just keep the install CD
of the software you use and voila. If you create only excell and word
documents you need only a 3 1/4 disk to save them
But if you create prog, image, sound all things that take place and that you
can't recover because they exist only on your HD and take a huge place
it become a pain.
Professionnaly on the AS400 I worded during 10 years we simply made
a save on magnetic tape of all the working "folder" each night.. (one daily backup taking about 2 hours)
and the whole machine each month.
We had also a big "anti fire safe" storage for all those magnetic tape that we keep 10 years...
Not really practicall for a home user but the only reliable solution to keep safe backup.
The main problem of ghost HD (RAID1/5) is that they don't keep a trace of old
version of files... if you mess a file on the main disk it will be also messed on the ghost.
Say you have a project with a nice paint you worked 2 month on it... make an error
with brush that repaint all in black, save and voila. not trace of your two month work.
(of course no creators keep only one file, usually they save with incremental name
but the problem of that you fill your HD after some month only)
All other solution (tape, CD-R, DVD-R) take time and are boring, as they are boring
we tend to not make them often, you end usually with a backup two month old when
your HD fail... Not to speak about DVD/CD that you can't read anymore.
A second disk with manual copy ? mhhh yes but depend how you organise that it
become a pain after a while, and it take time and require manual intervention...
what if you forget a crucial file ? Also same problem as before...
In fact unless they find a new storage media with no mechanic that can save several
GB (or TB) on a very small box and that can transfert those TB instantly there is no
really practicall, fast and full safe solution yet for home user....
It would be soo cool: you insert the lilte box in a slot, you press a button, your whole
computer saved 2 seconds later... say 30 small box one for each day of the month....
too cool
