Ngày tạo: 06/07/2022 | Cập nhật: 06/07/2022

This script to help you export the Mongo database collections to json file, I also using it to export database store in Mongo DB Atlas (aka Mongo DB Cloud) in-case I using a free-tier cluster (M0) or want to pull database to local.

Backup / export

This backup script to run on Windows OS, you'll need donwload database tools, extract and add bin folder to OS PATH to make command mongoexport available in CMD.

update MONGO_URI with correct connection string, name_of_collection* with real database collection list you want to export/backup, and your_database_name with an accordant name.

@echo OFF
echo === EXPORT MONGO DB ATLAS COLLECTIONS ===

SET "MONGO_URI=mongodb+srv://<**redacted**>@clusterxxx.mongodb.net/your_database_name"
SET "TODAY=%date:~10,4%-%date:~4,2%-%date:~7,2%"
SET "BACKUP_TO_DIR=%CD%/%TODAY%"

if not exist %BACKUP_TO_DIR% mkdir %TODAY%

for %%x in (
    name_of_collection_1
    name_of_collection_2
    name_of_collection_3
) do (
    mongoexport --uri="%MONGO_URI%" --collection="%%x" --out="%BACKUP_TO_DIR%/your_database_name_%%x_export_%TODAY%.json"
)

echo === export done ===
pause

Example we restore collection name events from file events.json:

mongoimport --uri="mongodb://mongos0.example.com:27017/reporting" --collection=events --file=events.json
