    I really like ZFS snapshots with offsite pull-mode sync using Jim Salter's sanoid/syncoid [1]. ZFS is the base for all OS/filesystems on top of it. If you have a good system for organizing ZFS datasets, and separating ephemeral from persistent data (e.g. [2]), then this is 90% of the backup requirements already fullfilled.

      And FreeBSD comes with native ZFS. MORE, it snapshots your OS before updates/upgrades, so you never ever screw up any upgrade.

        It's not native ZFS. They threw the native port away and replaced it with ZoL.
