# Creating an OBS Bucket

ModelArts uses OBS to store data and model backups and snapshots, achieving secure, reliable, and low-cost storage. Therefore, before using ModelArts, create an OBS bucket and folders for storing data.

#### Procedure

1. Log in to OBS Console and create an OBS bucket. For details, see Creating a Bucket. For example, create an OBS bucket named c-flowers.

   The created OBS bucket and ModelArts are in the same region.

2. Create a folder for storing data. For details, see Creating a Folder. For example, create a folder named flowers in the created c-flowers OBS bucket.
