They merged online backup, online storage and file sharing services into one product.

If you try this service you will notice that (contrary to most competitors):
- You can access your files in (true) real time with a web browser
- They really offer 250 GB (some competitors offer a fake unlimited web
space, they say “fair use”)
- You can share a file or many files with the 1-click-share functionality
- Some of your files will be uploaded very very fast (turboupload)
- The service and website are in 10 different languages

I’ve also found two useful guide to online backup on Wikipedia:

I’m surprised at this. I have loads of digitally stored photos. I bought an external 400 GB hard drive specifically for the job. I’ve only got maybe 200 GB of photos and video, but I thought I’d leave myself some more space. Now I’ve got a monstrous 750 GB internal on my computer, but the external serves as a great backup. I recently bought my first USB flash drive, and its 1GB capacity was surprisingly affordable. (￥2500, to be exact.) Given the lowering costs of digital storage media and the boost in the mega-pixel counts (which are incredibly overrated), I expect that next year the numbers would change significantly. You know? That’s my take anyway.
