I am not sure, why you would want to backup the badger DB, because DGraph comes with a built-in backup feature that dumps the database in a json like format.
I’ve achieved good results by running this query:
mutation {
export(input: {
destination: /path/to/backup/dir/
}) {
response {
message code
}
}
}
you can post this query as json to the admin route http://localhost:8080/admin
Hope this helps
