This snippet is a windows and linux version for MongoDB Backup. Just need to replace the MongoDB Binary for it to work. I had some dificulty doing "if (condition) && (condition) so I nested it.

mongobackup.bat

@echo off

mkdir e:\mongotemp

rem [ "admin", "config", "local", "database1", "database2" ]

rem "C:\Program Files\MongoDB\Server\4.0\bin\mongo.exe" --quiet --eval  "printjson(db.getMongo().getDBNames())" > input.txt
set /p mongodbs=<input.txt
FOR %%G IN (%mongodbs%) DO (
  if not %%G==[ (
    if not %%G==] (
      echo Backing Up %%G
      "C:\Program Files\MongoDB\Server\4.0\bin\mongodump.exe" --out e:\mongotemp --db=%%G
    )
  )
)

echo ### Compactando
