.SH SYNOPSIS
.sp
The \fBmongorestore\fP program writes data from a binary database
dump created by \fBmongodump\fP to a MongoDB
instance. \fBmongorestore\fP can create a new database or add
data to an existing database.
.sp
\fBmongorestore\fP can write data to either \fImongod\fP or \fBmongos\fP
instances, in addition to writing directly to MongoDB data files
without an active \fBmongod\fP\&.
.SH BEHAVIOR
.sp
If you restore to an existing database, \fBmongorestore\fP will
only insert into the existing database, and does not perform updates
of any kind. 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.

\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.

not match the hostname resolved by DNS.
.sp
This option is available only in MongoDB Enterprise.
.UNINDENT
.INDENT 0.0
.TP
.B \-\-db <database>, \-d <database>
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<db>\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 <collection>, \-c <collection>
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

.B \-\-oplogLimit <timestamp>
New in version 2.2.

.sp
Prevents \fBmongorestore\fP from applying \fIoplog\fP entries
with timestamp newer than or equal to \fB<timestamp>\fP\&. Specify
\fB<timestamp>\fP values in the form of \fB<time_t>:<ordinal>\fP, where
\fB<time_t>\fP is the seconds since the UNIX epoch, and \fB<ordinal>\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.

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

.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
