How does this compare to Duplicacy in terms of throughput?

#13Any discussion about backup should always include a shout out to one of the most beautiful versions of this: bvckup2
About 10 years ago the founder just decided to start writing the most streamlined, beautiful pieces of software he could - obsession around NTFS nuances to improve performance and reduce overhead to an unbelievable degree.
10 years later, it's still him (and maybe a few other folks) and the software is unbelievably polished.
Re: Kopia – Fast and Secure Open-Source Backup
#14I have been using Kopia for some time now after switching from Duplicity. Very happy with Kopia. You can just point Kopia at a GCS or S3 bucket and shove files there. Easy to restore files. You can list snapshots and files and do partial restores fairly easily. Old data gets expired on a timeline that you dictate.
Duplicity was a pain by comparison. I think Duplicity has a number of design flaws that become evident once you use it for a while.

#15I love the new tendency to use Polish (and other languages') names for programs!
The other day I heard someone use the word "żuk" referring to a bug, and I think it fits amazingly well.
Re: Kopia – Fast and Secure Open-Source Backup
#16I wonder how it compares to restic or borg. Besides the gui anyway…
Restic doesn't support compressing backups, and kopia does. Otherwise, the architectures appear to be very similar.
How much space do you typically save by compressing these days? Given that even smallish things like documents are already compressed archives, pictures/audio/movies of course already have heavy purpose-specific compression.
The main things I can still think of that are sparse on purpose are database files and disk images (not very mainstream, but also not uncommon). So like, a few gigabytes per terabyte (a few promille) unless you're really heavy on either databases or virtual machines?
I can see why one would like to enable it, but deduplication (which breaks if you naively implement compression, iirc that's why restic hasn't yet implemented it) is much more worth it because it enables incremental backups and you don't, for example, have to worry about making a copy of another system that has many of the same files (think game files or system files).

#17Another one? Ten years ago I had trouble finding anything, then over time I learned of duplicity (2002?!¹), bup (2010), restic (2015), borg (2010)... all basically solving the same problem of encrypted incremental backups.
The landing page doesn't mention why they made yet another solution. In the comments someone also mentions bvckup2. Is there an overview somewhere of all the different solutions? Any selling points here?
¹ That's way older than I expected, but it's also the first one I found and I stopped using it because it took many gigabytes on my then-250GB SSD for a local cache just to be able to do incremental backups. Maybe that's why I had the feeling I couldn't find anything good at the time.

It has a gui and works on Linux/Windows/MacOS. Also has both deduplication and compression.

I assume compression works well for source code and other developer artifacts. Obviously you have to do dedupe, then compression, then encryption.
