We just released the source code less than 2 months ago. The difference in contributor counts may not be this big in one or two years from now.

Thanks for your feedback. The reason I don't like open-source licenses is that I don't want for-profit companies to use my software without paying. The ideal license would be the one that requires them to pay while being appealin

Free or not free aside, my question is, does it matter to personal users between this free-for-personal-use license and any of those more permissive licenses like MIT, BSD, or GPL?

I noticed that, but didn't know if Borg has another meaning. I can understand why they forked the project, but in my opinion a name that makes the origin more obvious would have been better.

Author here. The experiments actually ran BorgBackup 1.1.0b6 as you can see from the Setup section. We liked to call it Attic out of the respect to the original Attic author.

We use a pack-and-split approach -- files are packed first (as if it is building a big tar file first, although this is only conceptual) and then split into chunks using a variable-sized chunking algorithm. You can customize the chunk size

The name and the license are two separate issues. I agree the name is confusing, however this is not intentional. As I explained in the other comment, I chose duplicacy because the domain name was available and this is a very good name for

Naming chunks by their hashes is not a new idea, but this technique along does not give you a practical backup tool. The deletion of unreferenced chunks becomes a hard problem, and the center piece of lock-free deduplication is the two-ste

I might be wrong but I want to hear more from you if you're a Borg developer. My understanding is that you may be able to have multiple clients uploading chunks at the same time, but you won't be able to exploit cross-client dedu

I think Amazon only blocked rclone's application key for Amazon Drive. There is no way for Amazon to prevent a third-party application from accessing S3, since users provide their own S3 credentials and Amazon doesn't know who is

I didn't want to sound like duplicity intentionally, but duplicacy.com was still available at that time and I thought it was a perfect name for a backup tool...

Duplicacy doesn't use the filesystem events APIs. Instead, it checks the timestamps and sizes to identify modified files and only back up these files by defaults. The main use case supported by Duplicacy but not any others including D

By "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".

Yes, there is a -vss option for the backup command.

Crashplan doesn't support cloud storages other than their own. Neither does it support cross-client deduplication ( https://www.facebook.com/CrashPlan/posts/10151056594185124 ).

Since most HN commenters are concerned about the source code availability, we'll definitely reconsider the licensing model.

by acrosync 10y ago
Our original goal was to make this tool completely free to personal users but charge for commercial uses. However, after some research we found that no such open source licenses exist, so we're currently considering alternatives.
