    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.

      I like to use ZFS snapshots of running systems and then create and upload the backup from them via the excellent Borgmatic. (I know you can't depend on snapshots for databases and similar, but it's worked until now™.)
