``initial_replication`` option
|
|
------------------------------
|
|
|
|
The ``initial_replication`` option determines how many snapshots zrepl replicates if the filesystem has not been replicated before.
|
|
If ``most_recent`` (the default), the initial replication will only transfer the most recent snapshot, while ignoring previous snapshots.
|
|
If all snapshots should be replicated, specify ``all``.
|
|
Use ``fail`` to make replication of the filesystem fail in case there is no corresponding fileystem on the receiver.
|
|
|
|
For example, suppose there are snapshosts ``tank@1``, ``tank@2``, ``tank@3`` on a sender.
|
|
Then ``most_recent`` will replicate just ``@3``, but ``all`` will replicate ``@1``, ``@2``, and ``@3``.
|
|
|
|
If initial replication is interrupted, and there is at least one (maybe partial) snapshot on the receiver, zrepl will always resume in **incremental mode**.
|
|
And that is regardless of where the initial replication was interrupted.
|
|
|
|
For example, if ``initial_replication: all`` and the transfer of ``@1`` is interrupted, zrepl would retry/resume at ``@1``.
|
|
And even if the user changes the config to ``initial_replication: most_recent`` before resuming, **incremental mode** will still resume at ``@1``.
