1. 备份
MongoDB提供了备份工具，mongodump.exe，在bin目录下，其用法如下：
mongodump.exe -h localhost -d database_name -o d:\mongodump
-h：MongDB所在服务器地址，例如：127.0.0.1，当然也可以指定端口号：127.0.0.1:27017
-d：需要备份的数据库实例，例如：database_name
-o：备份的数据存放位置，例如：d:\mongodump，当然该目录需要提前建立，在备份完成后，
系统自动在dump目录下建立一个database_name目录，这个目录里面存放该数据库实例的备份数据。
mongodump说明:
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)
--quiet silence all non error diagnostic
messages
--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
--gssapiServiceName arg (=mongodb) Service name to use when authenticating
using GSSAPI/Kerberos
--gssapiHostName arg Remote host name to use for purpose of
GSSAPI/Kerberos authentication
--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 directory
(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)
--dumpDbUsersAndRoles Dump user and role definitions for the
given database
2. 恢复
mongorestore.exe -h localhost -d database_name –directoryperdb d:\mongodump\database_name
-h：MongoDB所在服务器地址
-d：需要恢复的数据库实例，例如：database_name，当然这个名称也可以和备份时候的不一样，比如test2
–directoryperdb：备份数据所在位置，例如：d:\mongodump\database_name
–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，备份后添加修改的数据都会被删除，慎用.

Import BSON files into MongoDB.

GSSAPI/Kerberos authentication
--dbpath arg directly access mongod database files
in the given path, instead of

be used if a mongod is currently
accessing the same path
--directoryperdb each db is in a separate directory
(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)
--objcheck validate object before inserting
(default)
--noobjcheck don't validate object before inserting
--filter arg filter to apply before inserting
--drop drop each collection before import
--oplogReplay replay oplog for point-in-time restore
--oplogLimit arg include oplog entries before the
provided Timestamp (seconds[:ordinal])
during the oplog replay; the ordinal
value is optional
--keepIndexVersion don't upgrade indexes to newest version
--noOptionsRestore don't restore collection options
--noIndexRestore don't restore indexes
--restoreDbUsersAndRoles Restore user and role definitions for
the given database
--w arg (=0) minimum number of replicas per write
3. 单collection备份
mongoexport -h dbhost -d dbname -c collectionname -f collectionKey -o dbdirectory
-h: MongoDB所在服务器地址
-d: 需要恢复的数据库实例
-c: 需要恢复的集合
-f: 需要导出的字段(省略为所有字段)
-o: 表示导出的文件名
