Mongodump problem with large deployments #311

Open victor-ludorum opened 5 years ago

victor-ludorum commented 5 years ago

I have read in the MongoDB official documentation that mongodump is not good for large deployments and when the database is huge, then mongodump is not good. I want to know how mongodb_consistent_backup is handling that part. Because it is also using mongodump. Can anyone explain.

The answer is it's shard aware and you should shard large deployments. That said you could make it take binary backups with Percona Server but this is more complicated I believe the official tool is being talked about in Austin next month at the conference. But what do I know since I don't work there anymore?
