    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.

      Using this in production for 5 years now. We have a replicated MongoDB and one replica lives on a ZFS doing snapshot backups via syncoid. Love it.
