如果我们 zfs snap -r tank@20220129，所有子文件系统也会获得该快照。
如何将包含所有子文件系统的 tank 单个快照发送到新池（没有快照的历史基础）？
虽然 zfs send -R tank@20220129 将发送所有子 fs，但它也会发送所有快照。
（我们稍后可以删除所有这些快照，但这可能需要大量额外发送才能在完成后删除。）
似乎没有 zfs send -r 功能。

最后编辑：您说得对，您无法很好地处理递归（请注意克隆！！树中的每个克隆都需要单独制作）我理解断言，即在继承中复制的是函数，而不是继承的当前值，但我很难处理这是最理想的值的用例。我将提出功能请求。 当任何可修改属性从默认值改变时，所有子级都会自动更改为继承。我有一个加密根和 gen key ds，其中有许多非默认的活动子项。父母和孩子应该有一个属性，以便能够选择不获取或传递继承所有或一组属性。然后 zfs send -R -p 将以预期的方式运行。您的案例需要一个上游功能，通常只有单个快照想要递归发送，并且与从递归创建的快照中递归创建克隆相同是一个预期的选项，我很惊讶地发现它不存在。
我非常确定你可以做一个 zfs 克隆或类似下面的操作，而不是我原来的“如果快照出现，zfs 会将它们全部销毁；然后执行 zfs send | zfs recv 克隆，而不执行任何快照。”这是不优雅的、未经研究的和懒惰的，你无论如何都不需要克隆，只需像这样的一个 for 循环
for ds in $(zfs list -Ho name -r rpool); do \
zfs send ${ds}@20220129 | zfs recv -d newpool; done
但是克隆也可以工作，使用新的 zfs snap -r 和 zfs send -R 作为新克隆中的唯一一个快照。但是您无法递归克隆，因此无论如何都需要类似的 for 循环。或者，如果您不介意丢失所有 zfs-history，请将其 rsync 到一个干净的接收池并安装具有所需属性的数据集。
因此，我正在扩展我的解决方案，因为它并不那么容易或安全，而且我很快就会在一个实时但不是关键的系统上执行它。在我的例子中，我还将拆分我的镜像 vdev，并在 zfs recv 上进行一些池和 zfs 属性更改。
Zpool 和 zfs 递归操作可以改进，这一直是一个 bug bear。并且不清楚使用多个 zsys bootfs、zfs-mount-generator、zfs-zed.service 的最佳实践 (在 systemctl 暂停循环之后不会重新启动！)、持久数据集挂载，这些挂载不会反映启动时 zfs-list.cache/pool 的状态！Cananoical 似乎已经完成了对 root 和 zsys 可用性的 zfs 的推动。它并没有结束，只是因为它是一个 ubuntu 安装程序选项。

弄清楚如何将 void linux 和 zfsbootmenu 安装到这个 hacker 中，以及在新的 zfs 发送/接收递归之后所有 zsys 和 systemd zfs 自动挂载。拥有一致的继承和 zfs 接收所需的 -o 非常重要。
