@Lemjukes @Sunny It’s a KVM that you access over IP. It’s physically plugged into a machine’s HDMI and USB ports so, unlike software solutions, it can be used to access the BIOS/UEFI and system functions prior to hitting the desktop (like login managers and recovery consoles), and allows you to boot other operating systems and the like. It can also act as a PXE host for loading disk images, issue Wake On LAN to its connected machine, and likely a bunch of other convenience functions.
@gedaliyah If you’re not married to managed cloud services, services like rsync.net or a Hetzner storage box work very well. They require more effort, but you have complete control and can do some fun things (like using rclone’s crypt module with them). Plus rsync.net is super useful if your sources use ZFS.
Of the cloud providers, Backblaze is the one that anecdotally seems most popular.
