Service for backup decent amounts of data (about 400GB)?

Thank you all, found the solution which was right under the nose, but I didn't notice)
I did have a dedicated server. But there is a small screw, 250Gb, and about 100 is employed. Asked right now in techsupport, they can add another screw on 500GB for 300 rubles per month.

The computer does not take, but take from it hard. That problem will be solved.

Take the easiest dedicated server/vds with a large screw and recaptaci on it

More radical and reliable solution —
To put a home server where you can install and not a single winch.
The price for the hardware — the minimum system unit of 250-300 bucks + Vinci for 50 bucks apiece.
Of course if you have the opportunity and desire to it and throw it :)
This is good because no HCPs or other external storage (like Amazon) the rent you don't pay, but for home Internet, what the price is stable and does not depend on the number of gigabytes of backups.

hetzner server rent. If a month finish in 59 euros will cost 2 hard 750 in RAID1.

$ 100 per year for 400GB, but it does not have explicit sharing. This is the place for Picasa, mail and docs
