The personal version (which I use) is a true peer to peer application but it also offers other options. You can backup to an external drive, to a friend (peer), or to a cloud service (pay-for) through Crashplan. It seems to have the best of all worlds.

Schafer Thu, 15 Jul 2010 17:01:11 +0000 http://tech.philipsellers.com/?p=238#comment-1056 I realize this is an old post, but it comes up high in a search for "p2p backup". Unfortunately, after spending about 15 minutes on the CrashPlan site, I'm just having trouble seeing this as anything other than a glossy version of BackupExec, and I've been in this industry long enough (over two decades) that I was using BE when it was owned by Seagate, before Veritas or Symantec. CrashPlan--according to their own description--uses one "server" repository for multiple "client" sources; I would expect peer to peer to be headless, i.e., if there is a server, it's a tracker only, and the peers are all (in the client/server interpretation of p2p) clients AND servers. In fact, the diagram at the top of this page: http://b3.crashplan.com/business/how.html shows a typical client-server architecture (p2p would have lines between every device, not everyone to a server). In any case, perhaps they've simply shifted software models. Cucku appears to be closer to the model (multiple partners, and it's doubly implied in being able to set up one-way partnerships), but unfortunately, multiple partners are serialized...so it's close, but not quite there yet. In any case, you still gave me a place to start--as well as highlighting standard options I can still consider--so thank you for the writeup.

In Europe some countries upstream is tiny so trying to upload 100GB would just take so long I agree with you Philip upstream bandwidth is a big issue for lots of people.

I ended up using TrueSafe, I can back up offsite to my friend's pc. I had the same experience with Mozy. I ended up using TrueSafe, I can back up offsite to my friend’s pc.
