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?
For system files/configuration on my machines, timeshift set to run once a week.
For family photos and shared files, I built a pair of SFTP servers made from old HP thin-client PCs at two different geographic locations which automatically sync to each other once a day via cron job using vsftpd and lftp. Each one has both an NVMe and SATA SSD which run in a software RAID 1 configuration.
For any other files, a second local server also using vsftpd and two SSDs in USB enclosures. I manually back them up using rsync on an irregular basis.
