Hi Team, Myself balaji,

I tried to backup the mongodb database to s3 bucket, everything went well and good and the backup file stored in the s3 bucket also(security: disabled). But when i tried to backup the database by enabling the security in the mongod.conf file, am getting an error as mentioned below:

MongoDB server version: 4.2.9 { “ok” : 0, “errmsg” : “command fsync requires authentication”, “code” : 13, “codeName” : “Unauthorized” } please let me know where i did the mistake tq.

Hi Balaji,

To be able to use the fsync command with security enabled, you need to the hostManager role which comes with the admin user https://docs.mongodb.com/manual/reference/built-in-roles/#hostManager.

Run the fsync command while logged in as the admin user or another user with the admin role https://stackoverflow.com/a/57877333/4763270
