Duplicacy: cross-platform cloud backup tool based on lock-free deduplication
- de_dave 11y agoDuring beta testing only binaries are available. Why?! Surely this is the optimum time to provide source code, given the amount of trust one has to place in these things to not lose/misplace your data.
- acrosync 11y agoWe're going to make this free for personal uses but not sure at this time what licensing model we should adopt.
- ssatta 11y agoAs long as 'free for personal use' means 'closed source' then at least I would have a hard time trusting a tool backing up personal files into public cloud storage without transparency about how the crypto is implemented. I suspect that may also be the case for much of your 'personal use' target audience.
- acrosync 11y agoSince most HN commenters are concerned about the source code availability, we'll definitely reconsider the licensing model.
- lewisl9029 11y agoPlease do! The product & tech looks very promising. I'd hate to have to cross it off my shortlist due to trust issues.
- ssatta 11y agoIndeed please do! You're definitely scratching a very real itch here.
- gaboose 11y agoA thought: Do you think people would pay collectively (given the chance) like a fundraiser to publish the source, when a certain limit is reached? Maybe even pay the developer's bills that way? I wonder..
- Titanous 11y agoEspecially when crypto is involved. Given the large number of completely broken cryptosystems, making this open source will give it a fighting chance to not be entirely broken.
- eis 11y agoAnything that handles critical data and sends it encrypted to third parties needs to be open source in this day and age or wont be used by people who take their data serious. Actually it doesn't even need to be sent to third parties to hit the open source requirement. Having crypto involved like you said is reason enough.
- olalonde 11y agoWish I had seen this a few days earlier before throwing together my own AWS backup scripts (https://github.com/olalonde/offsite-aws-backup https://github.com/olalonde/offsite-aws-backup). Does this also support database backups?
- acrosync 11y agoIt should. The variable-size chunking algorithm works well with database files.
- BetaCygni 11y agoAttic + s3cmd sync works fine for me. At least, well enough that I won't be using a closed-source solution. If this is released as open source, great!
- eis 11y agoUnfortunately Attic seems to be abandoned (last commit 10 months ago). But there is a fork called Borg Backup that is actively maintained.
- mahyarm 11y agoWith s3cmd, don't you have to have a local copy of the backup somewhere although? So you have the content and the backup at the same spot, you can't directly backup to a remote server that way.
- BetaCygni 11y agoYes, you need to have a local backup. I actually prefer that, it's another backup location for when files are accidentally (or deliberately) deleted or damaged.
- Gazooo 11y agoHow is this different than http://duplicity.nongnu.org/ http://duplicity.nongnu.org/ ??
- acrosync 11y agoThere is a section comparing Duplicacy with others: https://github.com/gilbertchen/duplicacy-beta#comparison-with-other-backup-tools https://github.com/gilbertchen/duplicacy-beta#comparison-wit...

- harwoodr 11y agoWell, since it isn't open source - how does it compare with crashplan (another closed source, data deduplicating, free for personal use, cross platform backup solution...)
- acrosync 11y agoCrashplan doesn't support cloud storages other than their own. Neither does it support cross-client deduplication (https://www.facebook.com/CrashPlan/posts/10151056594185124 https://www.facebook.com/CrashPlan/posts/10151056594185124).
- kirushik 11y agoBTW, why does your comparison table says "Full Snapshot: No" for duplicity? One can definitely use `duplicity full` to explicitly ask for a full backup.
- acrosync 11y agoBy "full snapshot" I meant an incremental backup that still appears to be a full one. A full backup in duplicity is not an incremental backup so it is not qualified as a full "snapshot".

- aorth 11y agoI've been using Tarsnap for personal, encrypted, deduplicated backups for a few years. It's not shiny, but it works fantastically. https://www.tarsnap.com/ https://www.tarsnap.com/
- eis 11y agoI wish there was a version that one can run on their own servers.
- dexterdog 11y agoBut it is obscenely expensive. 1TB would cost you $256/month plus $256 to to your initial backup and another $256 if you ever need to restore.
- simonebrunozzi 11y agoI'm a big fan of Tarsnap and, of course, of Colin Percival.

- linuxready 11y agoVery interesting. Is it using VSS to backup on Windows ? Otherwise I don't see how it can really achieve a complete correct backup on Windows. The best cross-platform backup tool I have found is Burp. However it doesn't backup to cloud.
- acrosync 11y agoYes, there is a -vss option for the backup command.
