Easy, Reliable Distributed Storage and Backup?
RichiH writes "Most of you are the free IT staff of friends and family, just as I am. One of my largest headaches is backing up their data. What I am looking for allows for off-site storage on multiple server machines running Linux, has Linux & Windows clients that Just Work and require zero everyday effort (although a large-ish effort to set them up is just fine), allows for granular access control, is versioned and will, ideally, allow me to grab data automagically (think photo pool for your family where your mother, sister, etc., share each other's photos). This is something I've been trying to find for years, but I've never seen anything even closely resembling what I want. With the Wall Street Journal handing out its Technology Innovation Award to Cleversafe recently, I was once again reminded of this particular itch which needs scratching. Before I deploy it, I want to ask the Slashdot community for its opinion on that piece of software, and on potential alternatives. How do you solve this problem?"
If you try to roll backup and distributed file-storage into the same application, you're not going to get anything useful. Aunt Sally is going to want every single file including her OS and her tax returns backed up, in case her hard drive dies, but only wants the photos -- and only some of the photos, actually -- to be visible to Grandma Suzie. If Suzie can see every file on Sally's computer, and the entire history of each file, she's not going to be able to browse the photos in a way that's at all intuitive.
And worse yet, if Sally wants to send out links to her photos to fifteen of her friends by e-mail, she needs some sort of interface to mark parts of her backup as world-readable but the rest (like her passwords and e-mail) not. If the network backup program even lets you do this, it won't give Sally a UI that she'll be able to figure out.
You can certainly get network backup services: Mozy was mentioned in an earlier comment.
If you rethink your requirements in terms of your goals, you'll probably find that both rolled into one isn't what you want, and not just because a product doesn't exist at the moment that does that — a product that does that can't possibly have a good UI. If they shouldn't notice or care about how backups are being made, how are they going to figure out how to share photos with each other?
