config.json

{
  "mongo": "C:\\Program Files\\MongoDB\\Tools\\100\\bin\\mongoexport.exe",
  "host": "127.0.0.1",
  "port": 27017,
  "username": null,
  "password": null,
  "target": [
    {

      "collection": [
        "test",
        "test1"
      ]
    }
  ],
  "prefix": "mongodb-local-backup-json",
  "type": "json",
  "output": "E:\\mongo_backup\\",
  "cron": "*/1 * * * *"
}

config.toml

# Define the path of mongoexport executable
mongo = "C:\\Program Files\\MongoDB\\Tools\\100\\bin\\mongoexport.exe"
# MongoDB host
host = "127.0.0.1"
# MongoDB port
port = 27017
# username of MongoDB connection
# username =
# password of MongoDB connection
# password =
# prefix is the prefix of exported data file name.
prefix = "mongodb-local-backup-toml"
#
type = "json"
output = "E:\\mongo_backup\\"
cron = "*/1 * * * *"
# define the MongoDB db and collections in target, mlb can do the backup for multiple dbs and collections.
[[target]]
db = "test"
collection = ["test", "test1"]

config.yaml

mongo: C:\\Program Files\\MongoDB\\Tools\\100\\bin\\mongoexport.exe
host: 127.0.0.1
port: 27017
target:
  -
    db: test
    collection:
      - test
      - test1

type: json
output: "E:\\mongo_backup\\"
cron: '*/1 * * * *'

2. Run command

2.1 Run in Windows

# one time
./mlb.exe -c config.json -f json
./mlb.exe -c config.toml -f toml
./mlb.exe -c config.yml -f yaml
./mlb.exe -c config.yaml -f yaml

# cron job
./mlb.exe -c config.json -f json -d
./mlb.exe -c config.toml -f toml -d
./mlb.exe -c config.yml -f yaml -d
./mlb.exe -c config.yaml -f yaml -d

2.2 Run in Linux/Darwin

# one time
mlb -c config.json -f json
mlb -c config.toml -f toml
mlb -c config.yml -f yaml
mlb -c config.yaml -f yaml

# cron job
mlb -c config.json -f json -d
mlb -c config.toml -f toml -d
mlb -c config.yml -f yaml -d
mlb -c config.yaml -f yaml -d

Feature plans

1. Service

The service is about the Service in Windows, Linux and MacOS. With the Service, mlb can run in background and do the backup tasks automatically.

2. Notification

Aim to send message to IM software such as Telegram,Bark, WXWorks, DingTalk and so on.

Background

Why did I design this tool? A few months before, the data in MongoDB Standalone is broken by the hard disk failure, so I lost my data and can't not backup. So if you want to keep your data safe, it's better to use MongoDB ReplicaSet or backup more often.
