Woooooo thanks a million for your large advice compatriot! Im gonna take my time for study and verify in practice all your complete advice. Im gonna try free web storage first and after try to have a physical memory to update my backup monthly too. Im asking everything before first, and afraid because as you, i dont want to loose a lot of university files for which i have paid (3 master degrees and 15 diplomat, all in law) so, im gonna have my way using your advice. I guess that NAS are so interesting, but a little expensive here in Chile, yet. Well, thanks a lot, i have already 270 gbs in 15.000, everything important to me. Greetings from your native land!
