Distributed Internet Backup System

Posted by CmdrTaco on from the here-have-my-drive dept.

deadfx writes "Since disk drives are cheap, backup should be cheap too. Of course it does not help to mirror your data by adding more disks to your own computer because a fire, flood, power surge, etc. could still wipe out your local data center. Instead, you should give your files to peers (and in return store their files) so that if a catastrophe strikes your area, you can recover data from surviving peers. The Distributed Internet Backup System (DIBS) is designed to implement this vision."

  1. Use the Preview Button by Acidic_Diarrhea · · Score: 0, Flamebait
    "DCMA Me"? Should have used the preview button! Now I'll be forced to taunt you.
    Let's see, DCMA could mean...
    1. Dot-Com Managers Attack (me)
    2. Donkeys Can Marry Anyone
    3. Disney Cuts My Ass
    4. Dork Courier Management Act [surprisingly, that could actually be on-topic since couriers are now being overpaid to take tape backups to offsites]
    5. Don't Comment, Mod Away
    I'm not feeling very witty this morning.

    By the way, I'm not going to use the preview button before posting this so if my list is f'ed up, it's your fault for promoting the non-use of the preview button.

  2. Passwordless key? BAD! by runswithd6s · · Score: 0, Flamebait
    The first problem I see with this is that there is no reason to use a passwordless key. The only reason you would want to do so is to actually sign the data file. Signatures should NOT be done automatically, since they mean nothing. If you really want to sign the data file w/an automated signature, create a key just for signing, but use your 2048 bit key for encryption. Remember, you don't need a password to encrypt data.

    Now, I haven't looked at the code yet, but I'm assuming that the python script is simply a wrapper around an HTTP server, a MD5 or SHA1 hashing algorithm (for the filename), tar, bzip2, and some meta database to keep an index of files backed up.

    That being said, it's not a bad concept. If you have a trusted friend that will allow you to back up files on his machine, this wrapper should operate nicely. Otherwise, you can always do it by hand.

  3. Redundant.... by EmagGeek · · Score: 0, Flamebait

    I'm sure this has been said, but I didn't feel like reading through all the posts to make sure..

    but, this is simply the next iteration of p2p filesharing. The encryption is there to try to keep RIAA/MPAA off their backs, but I'll bet that this will be bastardized into a secure encrypted p2p network where snooping eyes will not be able to gather proof-of-crime...
