I am on windows and I am working in the creative industry so versioning systems are mostly out of the question because of file sizes and blob fileformats. My workstations are running bvckup2 and replicate everything to a local unRAID NAS. bvckup is configured to give me the last version of a file for 1 week. The unRAID NAS backups automatically to backblaze and every 3 months I replicate a dump of the data to my parents house via syncthing. I also use Macrium Reflect to keep cloned images of the boot drive. There is always one image after the initial setup and incremental backups every 2 weeks.
