Procedure

  1. Log in to the DCS console.
  2. Click in the upper left corner of the management console and select a region and a project.
  3. In the navigation pane, choose Cache Manager.
  4. Click the name of the DCS instance to display more details about the DCS instance.
  5. On the instance details page, click Backups & Restorations.

    Table 1 Parameters in a backup policy

    Parameter

    Description

    Backup Schedule

    Day of a week on which data in the chosen DCS instance is automatically backed up.

    You can select one or multiple days of a week.

    Retention Period (days)

    The number of days that automatically backed up data is retained.

    Backup data will be permanently deleted at the end of retention period and cannot be restored. Value range: 1–7.

    Start Time

    Time at which automatic backup starts. Value: the full hour between 00:00 to 23:00

    The DCS checks backup policies once every hour. If the backup start time in a backup policy has arrived, data in the corresponding instance is backed up.

    NOTE:

    Instance backup takes 5 to 30 minutes. The data added or modified during the backup process will not be backed up. To reduce the impact of backup on services, it is recommended that data should be backed up during off-peak periods.

    Only instances in the Running state can be backed up.

  7. Click OK.
