Full description
Sanoid is a policy-driven snapshot management tool for ZFS filesystems.
When combined with the Linux KVM hypervisor, you can use it to make your
systems functionally immortal.
More prosaically, you can use Sanoid to create, automatically thin, and
monitor snapshots and pool health from a single eminently human-readable
TOML config file at /etc/sanoid/sanoid.conf.
(Sanoid also requires a "defaults" file located at
/etc/sanoid/sanoid.defaults.conf, which is not user-editable.)
