如果我們 zfs snapshot -r Tank@20220129，所有子檔案系統也會獲得該快照。
如何將帶有所有子檔案系統的坦克的單一快照發送到新池（沒有快照的歷史基礎）？
雖然 zfs send -R Tank@20220129 將發送所有子檔案系統，但它也會發送所有快照。
（我們稍後可以刪除所有這些快照，但這可能需要大量的額外發送，只是為了在完成後刪除。）
似乎沒有 zfs send -r 功能。

最後編輯：你是對的，你不能很好地處理遞歸（不是克隆！樹中的每個樹都需要單獨製作）我理解這樣的斷言，即正在復制函數的繼承而不是繼承的當前值，但我很掙扎在用例中這是最期望的值。我將提出一個功能請求。 當任何可修改屬性從預設值變更時，所有子屬性都會自動變更為繼承。我有一個加密根和產生金鑰 ds，其中許多非預設值都屬於活動子項。父母和孩子應該擁有一項財產，以便能夠選擇不繼承或繼承全部或一組財產。然後 zfs send -R -p 將以預期的方式起作用。您的案例需要上游功能，通常只有單個快照需要遞歸發送，並且從遞歸創建的快照遞歸創建克隆是一個預期的選項，我很驚訝地發現它不存在。
我很確定您可以執行 zfs 克隆或類似的操作，而不是我原來的“如果遇到快照，zfs 會將它們全部銷毀；然後執行您的 zfs send | zfs receive 克隆，無需任何快照。”這是不雅的、未經研究的和懶惰的，你不需要克隆，只是像這樣的 for 循環
for ds in $(zfs list -Ho name -r rpool); do \
zfs send ${ds}@20220129 | zfs recv -d newpool; done
但克隆也可以工作，新的 zfs snap -r 和 zfs send -R 僅作為新克隆中的一個快照。但你不能遞歸克隆，所以無論如何都需要一個類似的 for 迴圈。或者，如果您不介意丟失所有 zfs 歷史記錄，則將其 rsync 到一個乾淨的接收池並安裝具有所需屬性的資料集。
所以我正在擴展我的解決方案，因為它不那麼簡單或安全，而且我很快就會在實時但不是關鍵的系統上進行它。就我而言，我還將拆分鏡像 vdev，並在 zfs recv 上進行一些池和 zfs 屬性變更。
Zpool 和 zfs 遞歸操作可以改進一直是個錯誤。且不清楚多個 zsys bootfs、zfs-mount-generator、zfs-zed.service 的最佳實務（在 systemctl 掛起週期後不會重新啟動！），持久性資料集掛載不會反映啟動時 zfs-list.cache/pool 的狀態！ Cananoical 似乎已經完成了對 zfs root 和 zsys 可用性的推動。這並不僅僅因為它是一個 ubuntu 安裝程式選項就結束了。

弄清楚如何將 void linux 和 zfsbootmenu 安裝到這個 hackery 中，以及在新的 zfs 發送/接收遞歸之後自動掛載所有 zsys 和 systemd zfs。具有一致的繼承和 -o 期望對 zfs 接收非常重要。
