Hm interesting name, I spent a few seconds on the site to figure out origin but no luck. "Kopia" means "copy" in Swedish and probably more Nordic languages, too. Very hard to pronounce in English so it would be interesting to hear it said.
My first impression was that it could have also been spanish "Copia" (copy), but built for KDE (thus following the naming trend of those apps)
Kopia: Fast and secure open-source backup software

#72I see no mention of any of that anywhere obvious. Do you get to just make up core properties of your software because it feels good?
Re: Kopia: Fast and secure open-source backup software
#73Can someone please help decide what is the "best" backup software? - Restic ( https://restic.net/ ) - Borg backup ( https://www.borgbackup.org/ ) - Duplicati ( https://www.duplicati.com/ ) - Kopia ( https://kopia.io/ ) - Duplicay ( https://duplicacy.com/ ) - Duplicity ( https://duplicity.us/ )
Bupstash ( https://bupstash.io/ ) beats Borg and Kopia in my tests (see https://masysma.net/37/backup_tests_borg_bupstash_kopia.xhtm... ). It is a modern take very close to what Borg offers regarding the feature set but has a significantly better performance (in terms of resource use for running tasks, the backups were slightly larger than Borg's in my tests).
It might be worth adding an asterisk there.

#74Compared to Veeam how is it?
Very different products and can't compare them. Veeam is enterprise-grade and used for a larger variety of mission-critical workloads. Kopia is meant for end-user backups (though folks use it for a bunch of other things too). Note that Veeam contributes to Kopia - https://www.veeam.com/sys451

Re: Kopia: Fast and secure open-source backup software
#75Too bad no one besides kopia does ecc, which is the reason I switched, but when I checked out why restic didn't do it, it was because they saw what other people did and apparently it's way too easy to make a bad implementation.
Re: Kopia: Fast and secure open-source backup software
#76We are trying to use it for large backups of a production item, and it has not been a complete smooth ride all along. We have many files (millions) and lots of churn over ~80Tb total. Kopia has exhibited some issues: - takes about 120GB (!) of ram to perform regular maintenance & takes about 5hrs to do so. There are ideas floating around to cherry pick the large inefficiencies in the GC code but it’s yet to be worked…
“ZFS on Azure via S3” is missing just an Apple technology to win the “mixing vendors randomly” bingo.

#78Re: Kopia: Fast and secure open-source backup software
#79Any comparisons to Restic? Looks like basically the same thing but with a GUI available. Edit: Found this very ad-hoc "benchmark" from over a year ago claiming that Kopia managed significantly better deduplication than Restic after several backups (what took Restic 2.2GB, Kopia did in https://github.com/kopia/kopia/issues/1809#issuecomment-1067... Edit Edit: Never mind, this benchmark was from before Restic supported…

Which is my current short-list for cross platform backup...
Re: Kopia: Fast and secure open-source backup software
#80I use Restic for personal backups and at work, but I thought I'd try Kopia to see if it'd be a good fit for my less techie relatives. This was about a year ago. The UI didn't seem like a good fit for those who are less technical. I don't remember the specifics. Does anyone have recommendations for backup services for the average user?
