According to my Backblaze reports, I have 261 GB of raw files stored online. This is essentially my 2010 wedding work plus my family photos, etc.
These 260 G of photos are also stored locally on my file server. That gives each Raw file a minimum of 3 copies.
When I get the go ahead (ie. the person who contracts me ships the last album), I'll archive 2010 to an external drive, keep the best shots for my portfolio directory, and make space on my working drive for 2011.
Besides Backblaze, my personal photos are all uploaded as full size jpegs to Flickr, Backblaze, an external drive called "media" that comes between work and home. Seems robust enough.
