# jimsalterjrs/sanoid

These are policy-driven snapshot management and replication tools which use OpenZFS for underlying next-gen storage. (Btrfs support plans are shelved unless and until btrfs becomes reliable.)

## What it is
Sanoid is a policy-driven snapshot management and replication tool for OpenZFS filesystems, configured via a human-readable TOML file and run from cron. It automatically takes, thins, and monitors ZFS snapshots, and its companion syncoid handles replication between pools and hosts.

## Use cases
- automatically take and prune hourly, daily, weekly, and monthly ZFS snapshots
- replicate ZFS datasets to a backup server over SSH
- roll back a system to a pre-infection snapshot after cryptomalware
- monitor ZFS pool health and snapshot aging from cron
- define per-dataset snapshot retention policies in a single config file

## When to avoid
- your filesystem is not ZFS (Btrfs support is shelved)
- you need cross-filesystem backup to non-ZFS targets or cloud object storage
- you want a GUI-driven backup solution
