Absolute best backup software for Linux/KVM? (alien.top)

Hi all,

I recently have spun up my home server once again and plan on using it for critical data, such as all of my photos and such. With that being the case, I absolutely must have rock solid backups - I plan on backing up to both a local drive and offsite (ideally to a self-hosted repo on another server at my brother's house, on his server, though I will use the public cloud e.g. Wasabi, B2, or Borgbase if it comes to that).

That being said, I would also prefer the following features if possible:

Bootable restore media with a graphical (or at least TUI) interface (this is the closest to a "must" as possible - I REALLY do not want to use the CLI when I'm stressed and trying to get my system running)
Ability to restore individual files or VMs with a web GUI (or TUI) interface within the OS
KVM/qemu support (host is CentOS Stream 9) for backing up and restoring entire VMs + configs with ease
Automated restore testing similar to Veeam's SureBackup, maybe utilizing KVM?
Web GUI for management/setup (or at least TUI)
Generic S3/Borg repo support

I'm willing to pay, and potentially hundreds of dollars (one time) or maybe a small monthly subscription (~$20/mo or equivalent annually max) at that, for a license for something that meets most of those ideals.

Thanks!

Proxmox with Proxmox Backup Server will do most of that if you were willing to move of CentOS Stream and onto Proxmox.

This is so close! The only huge (and probably deal-breaking) bummer is that it doesn't support S3 or Borg repos.

So far, my research has led me to believe Veeam Agent for Linux is probably the best. It doesn't have support for VMs directly, but I can just back up the critical folders on the hypervisor and that's more or less the same thing.
