Mongodump is an easy MongoDB backup software that generates high-quality BSON recordsdata contained in the MongoDB database. It’s a good backup choice for small MongoDB cases attributable to its ease of use and portability. This software affords instructions for backing up information on the question, assortment, or database stage. Moreover, MongoDB has a complimentary software referred to as mongorestore, which lets you restore information from distributed backups to a brand new or present MongoDB database.
So, now let’s comply with the steps to backup and restore information utilizing the Mongodump database command.
- Create Direct Backups
To run mongodump, use the syntax offered within the system command line as proven under:
mongodump <choices> <connection-string>
This construction additionally lets you connect with a Mongo database utilizing the -uri command adopted by a formatted string or flag, comparable to -user, -db, or -password. Nevertheless, you can’t use a number of flags in a single command.
You should use the default settings to create a Mongo Backup with the Mongodump command:
Mongodump
This may assume that the database is on port 27017 and situated on localhost (127.0.0.1), with none authentication. A dump folder shall be created within the present listing in the course of the backup process.
- Backup a Distant MongoDB Occasion
The –uri connection string lets you specify a number and a port.
Use the uri choice to attach:
mongodump --uri="mongodb://<host URL/IP>:<Port>" [additional options]
Join with the host choice: mongodump --host="<host URL/IP>:<Port>" [additional options]
Join with the host and port choices: mongodump --host="<host URL/IP>" --port=<Port> [additional options]
The under code reveals how you can create a backup of the distant MongoDB occasion:
mongodump --host="10.10.10.59" --port=27017
- Backup a Safe MongoDB Occasion
To make sure safe information backups, MongoDB’s Mongodump command allows the implementation of entry management mechanisms. To do that, it is advisable to present a Username, Password, and specify Authentication choices utilizing the next syntax:
mongodump --authenticationDatabase=<Database> -u=<Username> -p=<Password> [additional options]
For instance, you need to use the next command to hook up with a distant MongoDB occasion with a username and password:
mongodump --host=10.10.10.59 --port=27017 --authenticationDatabase="admin" -u="barryadmin" -p="testpassword"
- Choose the Databases & Collections
By utilizing the -db and -collection choices, you may specify which databases and collections must be backed up. The -db choice may be carried out independently, however you need to specify a database to pick a set. You may also take away a set from the backup course of through the use of the -excludeCollection choice.
To pick a Specify database:
mongodump --db=<Backup Goal - Database> [additional options]
To pick a set:
mongodump --db=<Backup Goal - Database> --collection=<Assortment Title> [additional options]
Run the next command to exclude the gathering:
mongodump --db=<Backup Goal - Database> --excludeCollection=<Assortment Title> [additional options]
- Altering the Backup Listing
The -out choice specifies the situation of the backup folder as follows:
mongodump --out=<Listing Location> [additional options]
To alter the backup listing to the “dbbackup” folder, run the next command:
mongodump --host=10.10.10.59 --port=27017 --authenticationDatabase="admin" -u="barryadmin" -p="testpassword" --out=dbbackup
- Create an Archive File
The Mongodump utility lets you construct an archive file. Now, the -archive choice can be utilized to specify a file and if there isn’t any file is offered, then the output shall be in the usual output (stdout).
Do not forget that you can’t use each the -archive and -out choices collectively.
mongodump --archive=<file> [additional options]
Run the next command to simply specify any archive file:
mongodump --host=10.10.10.59 --port=27017 --authenticationDatabase="admin" -u="barryadmin" -p="testpassword" --archive=db.archive
- Compressing the MongoDB Backup
Now allow us to see the method to compress these recordsdata. The backup recordsdata may be compressed with the -gzip choice and it’ll compress the person JSON and BSON recordsdata with the next command:
mongodump --gzip [additional options]
Compress the whole MongoDB database with the next command:
mongodump --host=10.10.10.59 --port=27017 --authenticationDatabase="admin" -u="barryadmin" -p="testpassword" –gzip
- Database Restoring
Together with backups, MongoDB additionally affords the ability to revive your information. The Mongorestore command will load information from Mongodumb backups and restore your Mongo database. However, if a doc’s id already exists within the database, the mongorestore command can’t overwrite it. Alternatively, Mongorestore will both create a brand new database or add information to an present one.
The Mongorestore command requires particular the trail to your dump listing:
mongorestore dump/
To revive it in your native atmosphere, you may also isolate and import the db1 database with the next command:
mongorestore --db=redbase --nsInclude="db1.*" dump/
This may restore all db1 collections that had been beforehand dumped. However this is not going to have an effect on the information in db2, regardless that each the dn1 and db2 are saved in the identical dump listing.
- Within the Mongostore command, you need to present the -uri flag or customary connection flags.
- Within the Mongostore command, to revive completely different collections, use the -nsInclude choice. It permits customers to pick a namespace when restoring the database collections.
Now you can comply with these steps to effectively backup and restore your MongoDB databases, making certain information safety and peace of thoughts. Whether or not you’re creating direct backups, backing up distant cases, or securing your backups with authentication mechanisms, Mongodump supplies complete help for all of your MongoDB backup wants.
