"MongoDB" Backup

Method One:

Use a file copy form to make a backup of the MongoDB data file.

[Mongo@localhost ~]$ cat mongo_back.sh #!/bin/sh
#su-mongo
Source/home/mongo/.bash_profile

#对数据库进行加锁, prevents data from being written, synchronizes data, and flushes dirty data to disk. To ensure that the files in the data directory are the most current data.

/opt/mongodb/mongodb-linux-x86_64-2.5.5/bin/mongo-start.sh <<eof

Db.fsynclock ()

Eof

#拷贝数据文件到备份目录中
#cp datafile to Backup/dir

Cp-r/opt/mongodb/db/mdsp/opt/backup/mdsp_bak


#解锁, the database is restored to a writable state
#unlock DB

/opt/mongodb/mongodb-linux-x86_64-2.5.5/bin/mongo-start.sh <<eof

Db.fsyncunlock ()

Eof

[Mongo@localhost ~]$

Method Two.

Use Mongodump to export data to a backup directory
