Its not a replacement for a physically seperate backup, so putting stuff in the cloud is good (though I'm sure it will get expensive, depending on how much you store).

I use SnapRAID for replication personally, because I like the flexibility it gives in terms of drives that make up the array, I like that it does not work the drives too hard, I like that I can drop drives in over time (to try and lessen coinciding failures) and I like that it works on top of a normal file/folder hierarchy on normal partitions (so I can access the files without SnapRAID should I need to). The cost is that I can lose up to the last day's worth of files (because the parity file is only updated nightly).
