corso VS kopia

Thank you for the Corso shoutout, u/funkyferdy!

I’m not seeing Corso mentioned, it’s newer and is the only open source tool for backups. Here’s Kias from Fonicom writing about his experience.

Definitely want to consider Corso if pricing is a big concern. Corso is free and open source, you provide your own S3-compliant storage. With only storage to pay for, you can be competitive with how you're offering it your clients. Here's a blog post by MSP Fonicom using Corso to great effect.

Corso, open source tool for de-duplicated and incremental backups. Lets you restore individual records from from the CLI.

The issue is you want to do backups that don't violate GDPR by where they're stored? Would a tool like Corso, which backs up to an S3 bucket you set up, cover that use case?

If you're trying to set up a cheap and effective backup tool for their Microsoft 365, consider spending some cycles on Corso, which let's an admin back up Exchange, SharePoint, and OneDrive data with a free and open source tool. You just pay the cost of your own S3 storage, and if you're really brave you can run S3 storage locally with MinIO

There's a free solution, Corso where you only pay for S3 object storage. Here's how to use Corso CLI to back up every single email: https://youtu.be/R1AOc2xz2Rg

Well, if you want cheap, nothing beats free and open-source Corso. 😀

Yuuuuuup. There's not much MS will do to support you here. It's these admin-related data losses that are one more reason to use a backup tool like Corso or Datto

I think Kopia would be great for your use case

https://kopia.io/

It has a great system to snapshot files but only store data if it's changed. I use it in an environment where I can't use something like zfs to snapshot data because I don't have the ability to make decisions about what filesystem we're using. It's been amazing, love it so much!

Thanks for the tip on Kopia. Setting it up now, looks perfect.

I've been happy with: https://kopia.io/

Fairly easy to configure, does snapshots to S3 and has a icon in my tray I can watch :)

Btw, kopia is one fine backup tool. Apparently borgbackup is good too.

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).

I think Kopia [1] is on its way to be that. I am sticking to Restic for now but it seems like the strongest contender.

I used their trial for a bit to test it out with Vorta [1] in a container. Vorta (and Borg) seemed to work fine, until I wanted to restore an archive and I noticed that my recent snapshots were completely empty. Probably because of a misconfiguration on my end though. But it made me look elsewhere. For me backups should be a fire, test and forget solution.

Recently I made the switch to Kopia [2] which seems to have feature parity with Borg (and Restic [3]). It also has a web UI which is way easier to work with than Vorta. And I can easily view, extract and restore individual files or folders from there. This gave me way more confidence about this solution. The only thing I really miss is that I cannot chose different targets for different paths. For instance, with Borg I was able to backup a partial of my Docker appdata to an external source. And I haven't found a way to do this with Kopia. Besides that I'm pretty happy with this solution and I would recommend it.

There's a few. Off the top of my head
