[MongoDB] 데이터 백업 및 복원

나는 아직도 단일구조로 mongoDB 를 사용하고 있는지라. 간단하게 백업 및 복원하는 방법만 알아본다.

 

mongodump 명령어

 

$>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
  --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         if dbpath specified, each db is in a separate
                           directory
  --journal                enable journaling
  -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)

 

db 중에 test 만 백업한다.

DATABASE: test   to     dump/test
        test.users to dump/test/users.bson
