Selfhosted

I'm a big fan of duplicati. You can install it on Linux, windows, (not sure about mac) and use it to send backups anywhere. Backup to your nas, to s3, smb share, whatever.

Sorry, this question might just reveal my ignorance, but what is the advantage of using all these programs over just using rsync? Yes, I am old and simple, but I'd love to know.

I use Syncthing on all my endpoints Windows and Linux (can't speak for Mac) to sync to my TrueNAS server. It has a built in tool to just back up to backblaze on a certain schedule.

I know you can use Syncthing with unraid in Docker. I have it set up so sync all endpoints to my server and then the server pushes the latest changes back to all the endpoints. This is overly redundant and you don't have to do it that way but all endpoints and my server would have to die at the same time before I lost any data. It's sort of a backup scheme in and on itself.

I don't do it to backblaze anymore, but the easiest way to back up is usually the simplest, and in my case that was rclone.

RClone supports so so many backends, and one of them is backblaze.

Set up rclone on unraid (either install it as a plugin or install it directly to the box in the shell), set up backblaze as the remote, and then set up a job to run it (again if you like UI try UserScripts, or if you want to do this bare metal than just add it to crontab)

I have my rclone split up into multiple shares personally because I like the granularity, then I run each one every night. I have a few protections turned on too so it can detect if too much has changed (like a ransomware attack) to kill the job and not run, sending me an error instead.

Bonus points, you can use a -crypt style thing on top of it if you'd like to encrypt your data uploaded to backblaze as well.

For workstation to unraid you have choices on how to set unraid as your backend

• SSH, easiest, probably most secure
• Local, meaning you've mounted your unraid as a local mount point/drive in Windows and just want to copy, it'll use the mount as the connection
• (S)FTP, would be more involved but just another option
• I'm sure there's a few more, I use SSH and/or local for workstation to unraid.

Or you can use whatever your OS bundles too, if you can mount a share in your OS (Idk what OS you can't do that) then you could use the built in backup utility). Play around, see what works best for you.

+1 to rclone

I use nextcloud to sync files from PC/phone to server and then Kopia CLI for daily backup to backblaze (also 2nd local backup). I start kopia web server for easier restore, but luckily I never had to do a real restore, only testing backups
