I 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?

I used to use Restic many years ago, when it wasn't clear what the future direction of Borg (a.k.a Attic) would be since development had mostly stalled. At the time it was missing some features and Borg managed to fix its issues quickly enough that I ended up using that. These days, from the minimal time I've spent looking at this, it seems that Borg and Restic offer basically the same feature set with similar perfor…

Borg2 will soon be released. It will indeed be a breaking change.

Borg 2 has been in development for nearly a year and a half [1] and may probably be released early next year, i.e., early 2024 (just a guess, seeing that even RC1 is not yet released and seems to have a lot of work to be done). Does anyone know how Borg 1.x and 2 would compare to Kopia? [1]: https://github.com/borgbackup/borg/issues/6602

Borg 2 is usable in my experience. It’s a breaking change. So tgr developer seems to be mulling over whether to release what is available or add in more breaking changes at this point.

Used it for a while, recently tried to restore some things and it failed, taking a really long time to restore some snapshots compared to other things I've tried. Switched to restic instead. Really like what kopia is but I'll wait a few more years before considering it for something, but right now I'm happy with restic. Too bad no one besides kopia does ecc, which is the reason I switched, but when I checked out why…

This has been my experience too with Kopia. I tried to restore a ~200 GB file (stored remotely on a Hetzner Storage Box), and it failed (or at least did not finish after being left for ~20 hours; there was also no progress indicator or status I could find in the UI). I also tried to restore a folder with about ~32 GB of data in it, and that also failed (the UI did report an error, but I don't recall it being useful).…

Out of curiosity, how recently was this?

Kopia is great, though it's worth noting for folks on Linux: non-UTF-8 paths aren't stored correctly [1] and xattrs aren't stored [2]. While most folks probably won't care about the former, the latter can could cause issues (eg. losing SELinux labels makes it difficult to restore a backup of the root filesystem on distros that use SELinux). [1] https://github.com/kopia/kopia/issues/1764 [2] https://github.com/kopia/k…

MacOS X makes heavy use of xattrs, too. > Yes, there's a whole bunch of things currently not captured at the filesystem level, including setuid/gid, hardlinks, mount points, sockets, xattr, ACLs, etc. That was three years ago and it sounds like things are only slightly better. These people are incompetent at making backup software.

I'm unsure if saying they're incompetent is the right thing. They just have a different priorities than you do.

Object lock support on S3-compatible storage does it for me. That was my only concern with restic, in the event of ransomware and compromised bucket credentials. https://kopia.io/docs/advanced/ransomware-protection/

Can 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/ )

My only complaint with Restic is that filesystem scans take too much time. I'm gonna switch over to ZFS probably though.

Do yourself a favor and use zfs as your primary backup, even though it means you'll have to replace your filesystem, it's just that good. Faster than any other backup software (because it knows what's changed from the last snapshot being the filesystem itself but external backup tools always have to scan the entire directories to know what's changed), battle tested reliability with added benefit like transparent comp…

This was a month ago. Appears it was v0.13.0.

Just for fun, since I still had it installed and haven't gotten around to cleaning up the remote data, I updated to latest (v0.14.1) and tried the restore tasks again.

Both the single file restore and the folder restore worked, though the single file restore still didn't have any progress indicator I could see.

Looking through the changelog, nothing really stood out to me as something which would have fixed this. Not really sure what went wrong the first time around, perhaps it was network issues with Hetzner?
