Can you please share your backup strategies for linux? I'm curious to know what tools you use and why?How do you automate/schedule backups? Which files/folders you back up? What is your prefered hardware/cloud storage and how do you manage storage space?
Nightly rsync to two NAS boxes in the house (TrueNAS Scale and a Synology). Docs go in NextCloud, hosted on a VM in my basement, which is also backed up to the Synology by Proxmox. Also backing up my main machine (Pop!_OS) and my wife’s laptop (ThinkPad E595, also Pop!_OS) using Spideroak One.
