If existing documents have the same value \fB_id\fP field in the target database and collection, \fBmongorestore\fP will \fInot\fP overwrite those documents. .sp Remember the following properties of \fBmongorestore\fP behavior: .INDENT 0.0 .IP \(bu 2 \fBmongorestore\fP recreates indexes recorded by \fBmongodump\fP\&. .IP \(bu 2 all operations are inserts, not updates. .IP \(bu 2 \fBmongorestore\fP does not wait for a response from a \fBmongod\fP to ensure that the MongoDB process has received or recorded the operation. .sp The \fBmongod\fP will record any errors to its log that occur during a restore operation, but \fBmongorestore\fP will not receive errors. .UNINDENT .sp The data format used by \fBmongodump\fP from version 2.2 or later is \fIincompatible\fP with earlier versions of \fBmongod\fP\&. Do not use recent versions of \fBmongodump\fP to back up older data stores. .sp New in version 3.0.0: \fBmongorestore\fP also accepts input via standard input. .SH REQUIRED ACCESS TO RESTORE USER DATA .sp Changed in version 2.6. .sp To restore users and \fIuser\-defined roles\fP on a given database, you must have access to the \fBadmin\fP database. MongoDB stores the user data and role definitions for all databases in the \fBadmin\fP database. .sp Specifically, to restore users to a given database, you must have the \fBinsert\fP \fIaction\fP on the \fBadmin\fP database\(aqs \fBadmin.system.users\fP collection. The \fBrestore\fP role provides this privilege. .sp To restore user\-defined roles to a database, you must have the \fBinsert\fP action on the \fBadmin\fP database\(aqs \fBadmin.system.roles\fP collection. The \fBrestore\fP role provides this privilege. .SH OPTIONS .INDENT 0.0 .TP .B mongorestore .UNINDENT .INDENT 0.0 .TP .B mongorestore .UNINDENT .INDENT 0.0 .TP .B \-\-help Returns information on the options and use of \fBmongorestore\fP\&. .UNINDENT .INDENT 0.0 .TP .B \-\-verbose, \-v Increases the amount of internal reporting returned on standard output or in log files.

By default, the \fBmongorestore\fP attempts to connect to a MongoDB instance running on the localhost on port number \fB27017\fP\&. .sp To connect to a replica set, specify the \fBreplSetName\fP and a seed list of set members, as in the following: .INDENT 7.0 .INDENT 3.5 .sp .nf .ft C /<:port>,<:port>,<...> .ft P .fi .UNINDENT .UNINDENT .sp You can always connect directly to a single MongoDB instance by specifying the host and port number directly. .sp Changed in version 3.0.0: If you use IPv6 and use the \fB
:\fP format, you must enclose the portion of an address and port combination in brackets (e.g. \fB[
]\fP). .UNINDENT .INDENT 0.0 .TP .B \-\-port \fIDefault\fP: 27017 .sp Specifies the TCP port on which the MongoDB instance listens for client connections. .UNINDENT .INDENT 0.0 .TP .B \-\-ipv6 Enables IPv6 support and allows the \fBmongorestore\fP to connect to the MongoDB instance using an IPv6 network. All MongoDB programs and processes disable IPv6 support by default. .UNINDENT .INDENT 0.0 .TP .B \-\-ssl New in version 2.6. .sp Enables connection to a \fBmongod\fP or \fBmongos\fP that has SSL support enabled. .sp The default distribution of MongoDB does not contain support for SSL. For more information on MongoDB and SSL, see http://docs.mongodb.org/manual/tutorial/configure\-ssl\&. .UNINDENT .INDENT 0.0 .TP .B \-\-sslCAFile New in version 2.6. .sp Specifies the \fB\&.pem\fP file that contains the root certificate chain from the Certificate Authority. Specify the file name of the \fB\&.pem\fP file using relative or absolute paths. .sp The default distribution of MongoDB does not contain support for SSL. For more information on MongoDB and SSL, see http://docs.mongodb.org/manual/tutorial/configure\-ssl\&. .sp \fBWARNING:\fP .INDENT 7.0 .INDENT 3.5 If the \fBmongo\fP shell or any other tool that connects to \fBmongos\fP or \fBmongod\fP is run without \fI\-\-sslCAFile\fP, it will not attempt to validate server certificates. This results in vulnerability to expired \fBmongod\fP and \fBmongos\fP certificates as well as to foreign processes posing as valid \fBmongod\fP or \fBmongos\fP instances. Ensure that you \fIalways\fP specify the CA file against which server certificates should be validated in cases where intrusion is a possibility. .UNINDENT .UNINDENT .UNINDENT .INDENT 0.0 .TP .B \-\-sslPEMKeyFile New in version 2.6. .sp Specifies the \fB\&.pem\fP file that contains both the SSL certificate and key. Specify the file name of the \fB\&.pem\fP file using relative or absolute paths. .sp This option is required when using the \fI\-\-ssl\fP option to connect to a \fBmongod\fP or \fBmongos\fP that has \fBCAFile\fP enabled \fIwithout\fP \fBallowConnectionsWithoutCertificates\fP\&. .sp The default distribution of MongoDB does not contain support for SSL. For more information on MongoDB and SSL, see http://docs.mongodb.org/manual/tutorial/configure\-ssl\&. .UNINDENT .INDENT 0.0 .TP .B \-\-sslPEMKeyPassword New in version 2.6. .sp Specifies the password to de\-crypt the certificate\-key file (i.e. \fI\-\-sslPEMKeyFile\fP). Use the \fI\-\-sslPEMKeyPassword\fP option only if the certificate\-key file is encrypted. In all cases, the \fBmongorestore\fP will redact the password from all logging and reporting output. .sp If the private key in the PEM file is encrypted and you do not specify the \fI\-\-sslPEMKeyPassword\fP option, the \fBmongorestore\fP will prompt for a passphrase. See \fIssl\-certificate\-password\fP\&. .sp The default distribution of MongoDB does not contain support for SSL. For more information on MongoDB and SSL, see http://docs.mongodb.org/manual/tutorial/configure\-ssl\&. .UNINDENT .INDENT 0.0 .TP .B \-\-sslCRLFile New in version 2.6. .sp Specifies the \fB\&.pem\fP file that contains the Certificate Revocation List. Specify the file name of the \fB\&.pem\fP file using relative or absolute paths. .sp The default distribution of MongoDB does not contain support for SSL. For more information on MongoDB and SSL, see http://docs.mongodb.org/manual/tutorial/configure\-ssl\&. .UNINDENT .INDENT 0.0 .TP .B \-\-sslAllowInvalidCertificates New in version 2.6. .sp Bypasses the validation checks for server certificates and allows the use of invalid certificates. When using the \fBallowInvalidCertificates\fP setting, MongoDB logs as a warning the use of the invalid certificate. .sp The default distribution of MongoDB does not contain support for SSL. For more information on MongoDB and SSL, see http://docs.mongodb.org/manual/tutorial/configure\-ssl\&. .UNINDENT .INDENT 0.0 .TP .B \-\-sslAllowInvalidHostnames New in version 3.0. .sp Disables the validation of the hostnames in SSL certificates. Allows \fBmongorestore\fP to connect to MongoDB instances if the hostname their certificates do not match the specified hostname. .UNINDENT .INDENT 0.0 .TP .B \-\-sslFIPSMode New in version 2.6. .sp Directs the \fBmongorestore\fP to use the FIPS mode of the installed OpenSSL library. Your system must have a FIPS compliant OpenSSL library to use the \fI\-\-sslFIPSMode\fP option. .sp \fBNOTE:\fP .INDENT 7.0 .INDENT 3.5 FIPS Compatible SSL is available only in \fI\%MongoDB Enterprise\fP\&. See http://docs.mongodb.org/manual/tutorial/configure\-fips for more information. .UNINDENT .UNINDENT .UNINDENT .INDENT 0.0 .TP .B \-\-username , \-u Specifies a username with which to authenticate to a MongoDB database that uses authentication. Use in conjunction with the \fB\-\-password\fP and \fB\-\-authenticationDatabase\fP options. .UNINDENT .INDENT 0.0 .TP .B \-\-password , \-p Specifies a password with which to authenticate to a MongoDB database that uses authentication. Use in conjunction with the \fB\-\-username\fP and \fB\-\-authenticationDatabase\fP options. .sp If you do not specify an argument for \fI\-\-password\fP, \fBmongorestore\fP will prompt interactively for a password on the console. .UNINDENT .INDENT 0.0 .TP .B \-\-authenticationDatabase New in version 2.4. .sp Specifies the database that holds the user\(aqs credentials. .UNINDENT .INDENT 0.0 .TP .B \-\-authenticationMechanism \fIDefault\fP: MONGODB\-CR .sp New in version 2.4. .sp Changed in version 2.6: Added support for the \fBPLAIN\fP and \fBMONGODB\-X509\fP authentication mechanisms. .sp Specifies the authentication mechanism the \fBmongorestore\fP instance uses to authenticate to the \fBmongod\fP or \fBmongos\fP\&. .TS center; |l|l|. _ T{ Value T} T{ Description T} _ T{ MONGODB\-CR T} T{ MongoDB challenge/response authentication.

T} _ T{ GSSAPI T} T{ External authentication using Kerberos. This mechanism is available only in \fI\%MongoDB Enterprise\fP\&. T} _ .TE .UNINDENT .INDENT 0.0 .TP .B \-\-gssapiServiceName New in version 2.6. .sp Specify the name of the service using \fBGSSAPI/Kerberos\fP\&. Only required if the service does not use the default name of \fBmongodb\fP\&. .sp This option is available only in MongoDB Enterprise. .UNINDENT .INDENT 0.0 .TP .B \-\-gssapiHostName New in version 2.6. .sp Specify the hostname of a service using \fBGSSAPI/Kerberos\fP\&. \fIOnly\fP required if the hostname of a machine does not match the hostname resolved by DNS. .sp This option is available only in MongoDB Enterprise. .UNINDENT .INDENT 0.0 .TP .B \-\-db , \-d Specifies a database for \fBmongorestore\fP to restore data \fIinto\fP\&. If the database does not exist, \fBmongorestore\fP creates the database. If you do not specify a \fB\fP, \fBmongorestore\fP creates new databases that correspond to the databases where data originated and data may be overwritten. Use this option to restore data into a MongoDB instance that already has data. .sp \fI\%\-\-db\fP does \fInot\fP control which \fIBSON\fP files \fBmongorestore\fP restores. You must use the \fBmongorestore\fP \fI\%path option\fP to limit that restored data. .UNINDENT .INDENT 0.0 .TP .B \-\-collection , \-c Specifies a single collection for \fBmongorestore\fP to restore. If you do not specify \fI\%\-\-collection\fP, \fBmongorestore\fP takes the collection name from the input filename. If the input file has an extension, MongoDB omits the extension of the file from the collection name. .UNINDENT .INDENT 0.0 .TP .B \-\-objcheck Forces \fBmongorestore\fP to validate all requests from clients upon receipt to ensure that clients never insert invalid documents into the database. For objects with a high degree of sub\-document nesting, \fI\-\-objcheck\fP can have a small impact on performance. You can set \fI\%\-\-noobjcheck\fP to disable object checking at run\-time. .sp Changed in version 2.4: MongoDB enables \fI\-\-objcheck\fP by default, to prevent any client from inserting malformed or invalid BSON into a MongoDB database. .UNINDENT .INDENT 0.0 .TP .B \-\-noobjcheck New in version 2.4. .sp Disables the default document validation that MongoDB performs on all incoming BSON documents. .UNINDENT .INDENT 0.0 .TP .B \-\-drop Modifies the restoration procedure to drop every collection from the target database before restoring the collection from the dumped backup. .sp With \fI\%\-\-drop\fP specified, \fBmongorestore\fP removes all user credentials and replaces them with users defined in the dump file. Therefore, in systems with \fBauthorization\fP enabled, \fBmongorestore\fP must be able to authenticate to an existing user \fIand\fP to a user defined in the dump file. If \fBmongorestore\fP can\(aqt authenticate to a user defined in the dump file, the restoration process will fail, leaving an empty database. .UNINDENT .INDENT 0.0 .TP .B \-\-oplogReplay Replays the \fIoplog\fP after restoring the dump to ensure that the current state of the database reflects the point\-in\-time backup captured with the "\fImongodump \-\-oplog\fP" command. For an example of \fI\%\-\-oplogReplay\fP, see \fIbackup\-restore\-oplogreplay\fP\&. .UNINDENT .INDENT 0.0 .TP .B \-\-oplogLimit New in version 2.2. .sp Prevents \fBmongorestore\fP from applying \fIoplog\fP entries with timestamp newer than or equal to \fB\fP\&. Specify \fB\fP values in the form of \fB:\fP, where \fB\fP is the seconds since the UNIX epoch, and \fB\fP represents a counter of operations in the oplog that occurred in the specified second. .sp You must use \fI\%\-\-oplogLimit\fP in conjunction with the \fI\%\-\-oplogReplay\fP option. .UNINDENT .INDENT 0.0 .TP .B \-\-keepIndexVersion Prevents \fBmongorestore\fP from upgrading the index to the latest version during the restoration process. .UNINDENT .INDENT 0.0 .TP .B \-\-noIndexRestore New in version 2.2. .sp Prevents \fBmongorestore\fP from restoring and building indexes as specified in the corresponding \fBmongodump\fP output. .UNINDENT .INDENT 0.0 .TP .B \-\-noOptionsRestore New in version 2.2. .sp Prevents \fBmongorestore\fP from setting the collection options, such as those specified by the \fBcollMod\fP \fIdatabase command\fP, on restored collections. .UNINDENT .INDENT 0.0 .TP .B \-\-restoreDbUsersAndRoles Restore user and role definitions for the given database. See http://docs.mongodb.org/manual/reference/system\-roles\-collection and http://docs.mongodb.org/manual/reference/system\-users\-collection for more information. .UNINDENT .INDENT 0.0 .TP .B \-\-w New in version 2.2. .sp Specifies the \fIwrite concern\fP for each write operation that \fBmongorestore\fP writes to the target database. By default, \fBmongorestore\fP does not wait for a response for \fIwrite acknowledgment\fP\&. .UNINDENT .INDENT 0.0 .TP .B \-\-writeConcern \fIDefault\fP: majority .sp Specifies the \fIwrite concern\fP for each write operation that \fBmongorestore\fP writes to the target database. .sp Specify the write concern as a document with \fIw options\fP\&. .UNINDENT .INDENT 0.0 .TP .B \-\-maintainInsertionOrder \fIDefault\fP: False .sp If specified, \fBmongorestore\fP inserts the documents in the order of their appearance in the input source, otherwise \fBmongorestore\fP may perform the insertions in an arbitrary order. .UNINDENT .INDENT 0.0 .TP .B \-\-numParallelCollections int, \-j int \fIDefault\fP: 4 .sp Number of collections \fBmongorestore\fP should restore in parallel. .UNINDENT .INDENT 0.0 .TP .B The final argument of the \fBmongorestore\fP command is a directory path. This argument specifies the location of the database dump from which to restore. .UNINDENT .INDENT 0.0 .TP .B \-\-dir string Specifies the dump directory. .UNINDENT .SH USE .sp See http://docs.mongodb.org/manual/tutorial/backup\-with\-mongodump for a larger overview of \fBmongorestore\fP usage. Also see the \fBmongodump\fP document for an overview of the \fBmongodump\fP, which provides the related inverse functionality. .sp Consider the following example: .INDENT 0.0 .INDENT 3.5 .sp .nf .ft C mongorestore \-\-collection people \-\-db accounts dump/accounts/people.bson .ft P .fi .UNINDENT .UNINDENT .sp Here, \fBmongorestore\fP reads the database dump in the \fBdump/\fP sub\-directory of the current directory, and restores \fIonly\fP the documents in the collection named \fBpeople\fP from the database named \fBaccounts\fP\&. \fBmongorestore\fP restores data to the instance running on the localhost interface on port \fB27017\fP\&. .sp In the final example, \fBmongorestore\fP restores a database dump located at \fB/opt/backup/mongodump\-2011\-10\-24\fP, to a database running on port \fB37017\fP on the host \fBmongodb1.example.net\fP\&. The \fBmongorestore\fP command authenticates to the MongoDB instance using the username \fBuser\fP and the password \fBpass\fP, as follows: .INDENT 0.0 .INDENT 3.5 .sp .nf .ft C mongorestore \-\-host mongodb1.example.net \-\-port 37017 \-\-username user \-\-password pass /opt/backup/mongodump\-2011\-10\-24 .ft P .fi .UNINDENT .UNINDENT .sp You can also \fIpipe\fP data directly into to \fBmongorestore\fP through standard input, as in the following example: .INDENT 0.0 .INDENT 3.5 .sp .nf .ft C zcat /opt/backup/mongodump\-2014\-12\-03/accounts.people.bson.gz | mongorestore \-\-collection people \-\-db accounts .ft P .fi .UNINDENT .UNINDENT .SH AUTHOR MongoDB Documentation Project .SH COPYRIGHT 2011-2015 .\" Generated by docutils manpage writer. .
