mongodb备份和还原

–备份单个表

mongodump-u superuser-p123456–port 27017 –authenticationDatabase admin -d myTest -c d -o /backup/mongodb/myTest_d_bak_201507021701.bak

–备份单个库

mongodump-u superuser-p123456–port 27017 –authenticationDatabase admin -d myTest -o /backup/mongodb/

–备份所有库

mongodump-u superuser-p123456–authenticationDatabase admin –port 27017 -o /root/bak

–备份所有库推荐使用添加–oplog参数的命令，这样的备份是基于某一时间点的快照，只能用于备份全部库时才可用，单库和单表不适用：

mongodump-h127.0.0.1–port 27017 –oplog -o /root/bak

–同时，恢复时也要加上–oplogReplay参数，具体命令如下(下面是恢复单库的命令)：

mongorestore-d swrd–oplogReplay /home/mongo/swrdbak/swrd/

–恢复单个库：

mongorestore-u superuser-p123456–port 27017 –authenticationDatabase admin -d myTest /backup/mongodb/

–恢复所有库：

mongorestore-u superuser-p123456–port 27017 –authenticationDatabase admin /root/bak

–恢复单表

mongorestore-u superuser-p123456–authenticationDatabase admin -d myTest -c d /backup/mongodb/myTest_d_bak_201507021701.bak/myTest/d.bson
