MongoDB之備份與恢復
MongoDB資料備份
在Mongodb中我們使用mongodump命令來備份MongoDB資料。該命令可以匯出所有資料到指定目錄中。
mongodump命令可以透過引數指定匯出的資料量級轉存的伺服器。
語法
mongodump命令指令碼語法如下：
>mongodump -h dbhost -d dbname -o dbdirectory
● -h：
MongDB所在伺服器地址，例如：127.0.0.1，當然也可以指定埠號：127.0.0.1:27017
● -d：
需要備份的資料庫例項，例如：test
● -o：
備份的資料存放位置，例如：c:\data\dump，當然該目錄需要提前建立，在備份完成後，系統自動在dump目錄下建立一個test目錄，這個目錄裡面存放該資料庫例項的備份資料。
備份整個資料庫

MongoDB資料恢復
mongodb使用 mongorestore 命令來恢復備份的資料。
語法
mongorestore命令指令碼語法如下：
>mongorestore -h <hostname><:port> -d dbname <path>
● --host <:port>, -h <:port>：
MongoDB所在伺服器地址，預設為： localhost:27017
● --db , -d ：
需要恢復的資料庫例項，例如：test，當然這個名稱也可以和備份時候的不一樣，比如test2
● --drop：
恢復的時候，先刪除當前資料，然後恢復備份的資料。就是說，恢復後，備份後新增修改的資料都會被刪除，慎用哦！
● <path>：
mongorestore 最後的一個引數，設定備份資料所在位置，例如：c:\data\dump\test。
你不能同時指定 <path> 和 --dir 選項，--dir也可以設定備份目錄。
● --dir：
指定備份的目錄
