Data Migration method

[bingbb47]

as the title, how to migrate a collection to another cluster? i have try to query the whole collection and insert , but there is no iterative query method;
the Data migration tools in milvus-tools can only read meta in mysql;
did you have any idea about how to migrate data with ETCD

We are building a buckup tool for milvus. The tool can extract vector data(not including index data) and metadata from a milvus cluster, then import the vectors into another milvus cluster. Users can specify target collection to export/import.

Expect milvus 2.2 ！

How soon will the buckup be ready? Is it open source? You can now find persistent data stored on minio, but there is no way to deserialize it

The backup tool is here: https://github.com/zilliztech/milvus-backup
Now it is in Beta stage. Read the README to know how to use it: https://github.com/zilliztech/milvus-backup/blob/master/README.md

Note: this tool only exports the original data, not including the index, you need to create index after restoring the data on another milvus(v2.2) cluster.
