I have seen many services which offer vast range of online Data backup, cloud storage, autosync. Dropbox, sugarsync, Box, Livedrive, Skydrive are to name few. I have also seen some personal cloud creating programs like Cloud Foundry, Eucalyptus, OpenStack etc.

So I (as well as many others on mobileread) have at least 3 options now to access my huge book library on-the-go:

1. Make account for one of these services. (Like dropbox upgrade)

But I am afraid because:

I've seen lots of cloud-storage companies come and go, so there's always a risk that <specific cloud service> will up and vanish.

2. I can start my own personal cloud and keep the server running 24/7. (Efficient Example)

But what if my home network gets offline?

3. I can carry an extra storage drive (Like this) in my bag and access content on mobile/iPad over wifi.

But you won't carry your bag everywhere, will you?

What do you prefer? What are other alternatives? What are your genius ideas?
