alxbrun Posted February 28, 2015 Report Share Posted February 28, 2015 Many of us are using Sync as a Dropbox replacement. The problem is that without an external peer (= physically external to my home that can be burglarized, burned, etc.), there is no true backup. I'm considered renting a box on OVH/AWS/Digital Ocean etc. but that's super expensive. One solution is peer to peer backup: I send you an key (with encrypted permission only, of course), you send me yours, and we both serve as the other remote backup. The problem now is that I have to find a "peer" to do that. Ideally I want to roughly match the data size and the bandwidth as well ("live" folder as opposed to long term archive that rarely changes). Has anybody heard about such a community? Maybe based around a simple website that would match peers. If not, what features do you think would important? Is there any major issue I forgot? Thanks,A.

alxbrun Posted February 28, 2015 Author Report Share Posted February 28, 2015 Have a look at this thread. Thanks for the link! The suggested solutions in that thread are:- http://maidsafe.net/- http://storj.io/- http://www.symform.comAll of these are full solutions/products by themselves, they try to solve much more than what I have in mind. More problematically, they don't use BitTorrent Sync or at least don't integrate nicely with it. I don't want a something that replaces BTSync, I want something that synchronizes some of my BTSync folders externally. Basically it would work this way:- I need to backup a total of 50G for instance- The service finds a peer with the same need- We exchange keys (with encrypted permissions only) and sync each others data The key value is not the always-on aspect, it's the secure backup.

blogisch Posted March 1, 2015 Report Share Posted March 1, 2015 If your main purpose here is backup, I wouldn't go with BTSync. Although I'm a fan. Syncing is not the same as making a backup. I use Crashplan for peer-backup.The personal edition is a real backup solution, scans for new files, encrypts them and uploads them to your friends.Without CrashPlan Cloud storage. I see my friends backup as one big encrypted file. So basically we provide eacht other storage, outside our homes. Quote Link to comment Share on other sites More sharing options...

Here here! I see my friends backup as one big encrypted file. So basically we provide eacht other storage, outside our homes. And you can set a storage quota for each peer.

alxbrun Posted March 2, 2015 Author Report Share Posted March 2, 2015 CrashPlan looks neat, but still:You have to "manually" find peers among your friends;and worse, you have to install and trust commercial software (my main concern being that CrashPlan itself be hacked and backdoored by a third-party). Such a risk a much, much lower with BitTorrent.I know that BTSync is sync, not backup, but still I think we could build a neat P2P backup service on top of it.

blogisch Posted March 2, 2015 Report Share Posted March 2, 2015 On top of it? Yes, that would be great!!! Idea?On top of the BT Sync API with another client, not just for folder/key pairs and monitoring folders (new and changed files), but also:- Keeping older versions.- Keeping deleted files.- Going back to a 'snaphot' a month ago, a year ago etc. As for the 'community' part: It would require a system to automaticaly detect the storage I need and the storage I host for others.If I needed a backup for 5 GB, with a 4 times replication, I could offer 20 GB myself. And on top of that: reporting about the 'health' status for my backups. When 4 strangers (hosting my backup) go down at the same time, I can't recover something. etc. Something like this would be neat I think. A more generic approach (not operational though) is The Ethereum project.https://www.ethereum.org/ I uses blockchain technology to exchange value. In this context the value would be 'storage'. Same as http://storj.io/ you already mentioned. Quote Link to comment Share on other sites More sharing options...
