This commit
- adds a configuration in which no step holds, replication cursors, etc. are created
- removes the send.step_holds.disable_incremental setting
- creates a new config option `replication` for active-side jobs
- adds the replication.protection.{initial,incremental} settings, each
of which can have values
- `guarantee_resumability`
- `guarantee_incremental`
- `guarantee_nothing`
(refer to docs/configuration/replication.rst for semantics)
The `replication` config from an active side is sent to both endpoint.Sender and endpoint.Receiver
for each replication step. Sender and Receiver then act accordingly.
For `guarantee_incremental`, we add the new `tentative-replication-cursor` abstraction.
The necessity for that abstraction is outlined in https://github.com/zrepl/zrepl/issues/340.

Send & Recv Options
|
|
===================

Send Options

::
|
|
|
|
jobs:
|
|
- type: push
|
|
filesystems: ...
|
|
send:
|
|
encrypted: true
|
|
...
|
|
|
|
:ref:`Source<job-source>` and :ref:`push<job-push>` jobs have an optional ``send`` configuration section.
|
|
|
|
``encryption`` option
|
|
---------------------
|
|
|
|
The ``encryption`` variable controls whether the matched filesystems are sent as `OpenZFS native encryption <http://open-zfs.org/wiki/ZFS-Native_Encryption>`_ raw sends.
|
|
More specifically, if ``encryption=true``, zrepl
|
|
|
|
* checks for any of the filesystems matched by ``filesystems`` whether the ZFS ``encryption`` property indicates that the filesystem is actually encrypted with ZFS native encryption and
|
|
* invokes the ``zfs send`` subcommand with the ``-w`` option (raw sends) and
|
|
* expects the receiving side to support OpenZFS native encryption (recv will fail otherwise)
|
|
|
|
Filesystems matched by ``filesystems`` that are not encrypted are not sent and will cause error log messages.
|
|
|
|
If ``encryption=false``, zrepl expects that filesystems matching ``filesystems`` are not encrypted or have loaded encryption keys.

|
|
|
|
:ref:`Sink<job-sink>` and :ref:`pull<job-pull>` jobs have an optional ``recv`` configuration section.
|
|
However, there are currently no variables to configure there.
