Thanks for your informations and sorry to post off topic

I usually backup data on multiples copies of DVD-Rs. This time I got wrong and
bought some DVD-RWs because they were cheaper. Can I rely on DVD-RWs or should
I backup on DVD-Rs as usual ?

there was a link at slashdot recently, covering exactly that:

http://rss.slashdot.org/~r/Slashdot/slashdot/~3/59924512/article.pl

the summary was that RW's and -R are much less reliable than +R, but there 

are also details about various chemicals used.

I never rely on DVD-Rs because its so dependent on the brand combination 

between burner and DVD-R. If I verify a DVD I get about 5% failures !!!! 

(Which doesn't mean its entirely impossible to read it) But its 

The cheapest solution (cost per GB) anyway is to use external harddrives 

for BU. If you only switch them on for the backup, and recopy them if 

the technology changes it seems more safe. If your really anxcious, use 

a raid system, and if you're paranoic, keep another copy at a different

magnitudes worse than CD-R.

Well, I currently use CDs and DVDs, usually in 2 or 3 copies each (a kind of

I didn't know the external disks were the cheapest solution. I was only thinking

that if the external disk breaks for some reason, you loose everything ...

Well, I currently use CDs and DVDs, usually in 2 or 3 copies each (a kind of
