Currently zrepl is way above my pay-grade...

but if anybody else wants to read about this (the tagline "helps you configures zfs backups" – wasn't helpful to me) technology, here is the zrepl quickstart guide:

From zrepl guide, example use-cases:

•) Continuous Backup of a Server

•) Local Snapshots + Offline Backup to an External Disk

•) Fan-out replication

Just use an LLM, describe what you need and you get a commented config that does what you need.

I use it for:

- job 1: every 15 minute autosnapshot and cleanup

- job 2: push encrypted snapshots to an external harddrive via cronjob and signal

- job3 (another server): pull snapshots from the main server via ssh for ransomware resistant backups (mainserver cannot access backupserver at all)
