But I never decided about which service to use (images saved in full not recompressed resolution, management, reliability, ...).

In 2006, my hard disk died and I lost a lot of data: lots of photos, essentially all my mails (I was using POP3 back then), and a lot more. Since then, I'm trying to make backups more or less regularly (more less than more ;) ) And you should make a backup of the photos, loosing them is really annoying, believe me! :) I had several crashes during my life, though for most I had backups or could somehow else rescue most of the things.

But actually most interesting stuff is now also on my web pages, in some SVN Repositories or on some server. The only thing lost would be private photos - bad enough, but I am too lazy. :-) How many total loss of data did you had in your life?
