TL;DR @ bottom

Over the last year I’ve dove head first into selfhosting various services and apps on an UNRAID server. It’s my first real experience with Linux short of fiddling with a dual boot of Pop!_OS. So that alone has already been quite the ride. Thankfully, UNRAID supports docker compose and has it’s own Community App store where there are very few extra steps to get an app to work short of installing dependencies (MariaDB, Postgres, Redis, etc).

I am trying to be militant in my backups of mostly important files. Critical documents and photos, that sort of thing. Right now I have two copies on the same Win10 PC (two different drives) that backup nightly to iDrive. I recently started testing Backblaze Personal as well from the same computer. What I want to do is get to a point where the other Win10 PCs, MacOS laptops, and my yet to be built Linux desktop are all backed up to the server locally, then shuttled off to something like B2 on a nightly basis. Seemingly there is absolutely no consensus on the best cross platform app to backup the various clients. I currently have Time Machine backing up the laptops to the server, but that’s it. Nothing else in the house is touching the server outside of Immich pulling photos from phones when we’re back on network.

I keep trying to wrap my head around the CLI only options like Restic, Borg, and Kopia but I can’t get to a point that I’m confident enough to ensure I’m backed up and safe as far as data integrity. So that led me to apps with GUIs. I’ve tried UrBackup, BackupPC, KopiaUI, and Duplicacy. That last one is the only one I can get to work reliably and that is backing up server data to B2 right now. I’m still in my trial period for it so nothing set in stone in that regard.

I did see Vorta for Borgbase, but it doesn’t have a Win10. UrBackup refuses to work with MacOS for whatever reason. KopiaUI can’t see directories on the server which I’m guessing is permissions issues and the client side won’t accept an http://ip:port address, instead requiring https and I’m not sure if that’s possible to get around. BackupPC I can’t get to connect to the clients and that project seems somewhat stale with no updates in the last few years.

I’m comfortable hunting for solutions but seemingly the various support forums have a lot of assumptions in regards to prior knowledge of these products and I’m just not connecting the dots.

TL;DR: I apologize that this is so lengthy, but I’m honestly just not sure what to do at this point. I need (in my mind) the following as a solution:

• Compatibility with Win10, MacOS, and Linux clients
• Can back up to a local repository on UNRAID
• Has a GUI (because I apparently am too stupid for CLI-only)
• Would be nice to also backup to remote buckets like B2 or others but I can leverage something like Rclone GUI for that

Anyone have any advice on either solutions or resources I can dig into to accomplish this?
