mongoexport -d my_mongodb -c choice -o choice.dat
參数说明:
-d 指明使用的库, 本例中为” my_mongodb”
-c 指明要导出的表, 本例中为”choice ”
-o 指明要导出的文件名称, 本例中为”choice .dat”
-h server地址
2.导入数据
mongoimport -d my_mongodb -c choice choice .dat
參数说明:
-d 指明使用的库, 本例中为” my_mongodb”
-c 指明要导入的表, 本例中为”choice ”
3.整库备份：
mongodump -h dbhost -d dbname -o dbdirectory
-h：MongDB所在server地址，比如：127.0.0.1，也能够指定port号：127.0.0.1:27017
-d：须要备份的数据库实例，比如：test
-o：备份的数据存放位置，比如：c:\data\dump。当然该文件夹须要提前建立，在备份完毕后，系统自己主动在dump文件夹下建立一个test文件夹，这个文件夹里面存放该数据库实例的备份数据。
查看具体帮助信息例如以下
D:\tool\mongodb\bin>mongodump --help
Export MongoDB data to BSON files.
options:
--help produce help message
-v [ --verbose ] be more verbose (include multiple times
for more verbosity e.g. -vvvvv)
--version print the program's version and exit
-h [ --host ] arg mongo host to connect to ( <set
name>/s1,s2 for sets)
--port arg server port. Can also use --host
hostname:port
--ipv6 enable IPv6 support (disabled by
default)
-u [ --username ] arg username
-p [ --password ] arg password
--authenticationDatabase arg user source (defaults to dbname)
--authenticationMechanism arg (=MONGODB-CR)
authentication mechanism
--dbpath arg directly access mongod database files
in the given path, instead of
connecting to a mongod server - needs
to lock the data directory, so cannot
be used if a mongod is currently
accessing the same path
--directoryperdb each db is in a separate directly
(relevant only if dbpath specified)
--journal enable journaling (relevant only if
dbpath specified)
-d [ --db ] arg database to use
-c [ --collection ] arg collection to use (some commands)
-o [ --out ] arg (=dump) output directory or "-" for stdout
-q [ --query ] arg json query
--oplog Use oplog for point-in-time
snapshotting
--repair try to recover a crashed database
--forceTableScan force a table scan (do not use
$snapshot)
4.整库恢复：
mongorestore -h dbhost -d dbname –directoryperdb dbdirectory
-h：MongoDB所在server地址
-d：须要恢复的数据库实例，比如：test，这个名称也能够和备份时候的不一样，比方test2
–directoryperdb：备份数据所在位置，比如：c:\data\dump\test。这里为什么要多加一个test。而不是备份时候的dump
–drop：恢复的时候，先删除当前数据。然后恢复备份的数据。就是说，恢复后。备份后加入改动的数据都会被删除
