Backup only selected database

Open ya-kostik opened this issue 6 years ago • 5 comments

Hi!

How I can selecting database to backup? Now all databases are being copied. How can I specify a name for one of them?

Hi @ya-kostik. All databases/collections are backed up by this tool, by design.

You're able to restore only a specific database/collection using the mongorestore '--db=' and '--collection=' flags.

Thank you @timvaillancourt!

Do I get it right, that it's a feature, not a bug? Does this drive and network overload?

Hi @ya-kostik I would say backing up a single database is a feature request, not a bug.

Hi @timvaillancourt, It would be nice!

I would argue this should not be a feature as the name implys a consistent backup which can not be a single schema if any table of the schema is sharded. If it's not sharded mongodump --oplog --database solves this already
