Let’s Dump (backup)!

If we have installed MongoDB on our computer, we have to dump by mongodump

Run the bottom line. And we now have dump directory.

mongodump --host --port 27017

We also can choose where to locate dumped files will be located by --out

I used default host and port which are and 27017.

mongodump --out ~/mongo_backup --host --port 27017

If you have secured up by user name and password, you can use -u and -p

mongodump --out ~/mongo_backup --host --port 27017 -uusername -ppassword

You can also choose specific database to dump by using --db

mongodump --out ~/mongo_backup --host --port 27017 -uusername -ppassword --db dbname

So, next line will be completed version of dump cli.

mongodump --out 덤프지정위치(디렉터리) --host --port 27017 -uusername -ppassword --db dbname

Let’s Restore!

So you dumped your mongo databases.

So let’s restore from it.

You can use mongorestore this time. (if you already installed mongodb on your computer)

mongorestore --host --port 27017 -uusername -ppassword --drop dbname_which_you_want_to_drop_on_existing_db --db dbname "directory path which have dumped files"

--drop option will be used when you want to drop the database which is duplicated name with database name you want to backup.

So, next line will be completed example of restore cli.

mongorestore --host --port 27017 --drop myblog --db myblog ~/mongo_backup
