How Do I Download a Backup File of a Day from the OBS Bucket?

This topic describes how to use obsutil to download a backup file of a day from the OBS bucket to the local host.

  • Ensure that source objects in the OBS bucket do not change. Otherwise, the download may fail or data may be inconsistent.
  • If the objects to be downloaded are in the OBS Archive storage class, you must restore the objects first. Otherwise, the download fails.

Procedure

  1. Log in to a server as user root using a key or password.
  2. Run the following command to recursively download all files and folders (including the folder itself) in the bucket to a local path:

    ./obsutil cp obs://obs_path/Year/Month/Day/Local path -r -tempFileDir= a specified path -f

    In the preceding command:

    • obs_path: OBS bucket path, for example: obs-sap/hana
    • Year/Month/Day: directory of a folder in the OBS bucket. For example: 201905/28.
    • Local path: path where the files are stored on the local host. For example: src1.
    • tempFileDir= a specified path: Directory for storing temporary files during multipart download. The default value is the value of defaultTempFileDir in the configuration file. You can also specify a path.
      • Temporary files generated during multipart download are stored in this directory. Ensure that the user who runs obsutil commands has the write permission on the path.
      • The available space of the path must be greater than the size of the objects to be downloaded.

    For example, in the obs-sap bucket, download the backup files of May 28, 2019 to the local path src1. The command is as follows:

    ./obsutil cp obs://obs-sap/hana/201905/28 /src1 -r -tempFileDir=/hana/backup -f
