無法使用 rsync 將目錄從遠端主機拉到本地

我的問題只是我試圖解決的一個更大問題的一小部分。

該問題始於rsync非常複雜且由 ansible 建構且不起作用的命令……此處報告：

我希望從一個簡單的 rsync 命令開始，將文件夾從遠端主機複製到本地。

它複製的是遠端是一個文件，但如果遠端是一個目錄則失敗。

Rsync 為文件工作：

但是，當我提供目錄而不是文件時，它不起作用。

請建議。

根據rsync --help：

–recursive, -r 遞歸到目錄

因此，當您要複製目錄時，您必須添加-ror--recursive選項rysnc:

/bin/rsync -rv myremoteuser@myremotehost:/tmp/Deployments/ /web/playbooks/automation/getfiles/tmpfiles/4/E5EA787E/myremotehost/

使用rsync -a代替普通的rsync.

如果沒有-a( --archive) 標誌，您既不會遞歸複製，也不會獲得文件元數據。至少，需要使用 ( ) 複製的文件修改時間 ( )mtime才能-t有選擇地跳過它認為已複製的文件。如果確定文件的大小和最後修改時間在源和目標上相同，則它更願意避免執行校驗和，但顯然如果沒有將文件修改時間複製到目標，這些將不匹配並且無法優化其傳輸算法。--times``rsync``rsync``rsync
