Ladies and gentlement, now this tools plugin includes
support for dump too.
This means that you have the full data lifecycle at your disposal:
Dump data from a cluster of your choice into an archive.
Then, restore the archive back into a different cluster.
Under the hood, this uses functionality from
mongodump and mongorestore although intentionally less options
are exposed to make things easier.
For advanced use, using mongodump and mongorestore is encouraged.
