# Backing up an SSAS database
<a name="SSAS.Backup"></a>

You can create SSAS database backup files only in the `D:\S3` folder on the DB instance. To move the backup files to your S3 bucket, use Amazon S3.

You can back up an SSAS database as follows:
+ A domain user with the `admin` role for a particular database can use SSMS to back up the database to the `D:\S3` folder.

  For more information, see [Adding a domain user as a database administrator](SSAS.Use.md#SSAS.Admin).
+ You can use the following stored procedure. This stored procedure doesn't support encryption.

  ```
  exec msdb.dbo.rds_msbi_task
  @task_type='SSAS_BACKUP_DB',
  @database_name='myssasdb',
  @file_path='D:\S3\ssas_db_backup.abf',
  [@ssas_apply_compression=1],
  [@ssas_overwrite_file=1];
  ```

  The following parameters are required:
  + `@task_type` – The type of the MSBI task, in this case `SSAS_BACKUP_DB`.
  + `@database_name` – The name of the SSAS database that you're backing up.
  + `@file_path` – The path for the SSAS backup file. The `.abf` extension is required.

  The following parameters are optional:
  + `@ssas_apply_compression` – Whether to apply SSAS backup compression. Valid values are 1 (Yes) and 0 (No).
  + `@ssas_overwrite_file` – Whether to overwrite the SSAS backup file. Valid values are 1 (Yes) and 0 (No).
