Hope you be Happy with the cloud. One Nas Box at Home Two drives. Keep one at a friends house the other in the Nas..
Looking for a provider too.I have two drives in my main PC, Data and Backup.
Backup then gets copied to a HP Gen8 server
The problem is I do it manually.
Next stage is to copy it to the cloud but I haven't decided on a provider yet.
How will you keep your photo's in sync with amazon? Can you create a desktop folder or something? I use robomirror so just wondering how I would map it to amazon
