I want to do backup of last 10 days data only based on my column LastModifiyDate in mongo.

mongodump --gzip --db=mongo-database --collection=Records --out=F:\backup\ –query ‘{LastModifyDate: {$gt: ISODate(‘2021-07-15T07:00:00.000Z’)}}’

Error Received:

Error: 2021-07-26T10:58:40.893-0700 positional arguments not allowed: [{$gt: ISODate(‘2021-07-15T07:00:00.000Z’)}}’]
