Is there any good online backup company supporting redhat?

Hi, guys.

I'm using redhat for a year, and recently realizing how important it
is to backup my data.
I have an another hard drive for backup using Grsync.

But still want to use online backup, because some times I want to work
at home, which is windows machine.
I guess most online backup sites provide free 2GB. I think it's enough
for me.

So, I'm looking for free onlinebackup supporting redhat.

I tried to install dropbox, but it required nautilus-extension, which
I couldn't fine a way out.
thanks guys.

p.s. I wish redhat release version 6 soon.
