Extremely frequent diff based backups? My personal preference is to rsync to a backup host in a daily cron. Hourly for important directories. That backup host then runs rsnapshot [1] locally and the snapshots are made read-only. Important files are then backed up off-site. rsnapshot is just a perl script that creates multiple diff snapshots and uses hardlinks to save space. It is available for most distros. I believe it is also in macports and homebrew for mac. [1] - https://wiki.archlinux.org/title/rsnapshot https://wiki.archlinux.org/title/rsnapshot
