Modifying the Properties of a Backup Plan

Modifying the Properties of a Backup Plan

This operation allows you to modify the backup plan to meet your requirements.

Prerequisites

A backup plan has been created on the storage system.

Procedure

  1. Choose Data Protection > CloudBackup > Backup and Restoration > Backup Plan.
  2. Select the desired backup plan and click Properties.

    The Properties of Backup Plan dialog box is displayed.

  3. Modify the basic information of the backup plan.

    Table 3-13 describes the parameters.

    [Example]

    -

  4. Click the Backup Policy tab and modify the backup policy.

    1. Modify the execution schedule.

      There are two types of execution schedules: Periodically and Once. You can only modify the execution time of a schedule, but cannot modify the type of the execution schedule.

      • Periodically
        1. Specify Weeks in a Month. Backup tasks will be performed in these weeks of each month.
        2. Specify Days in a Week. Backup tasks will be performed on these days in each week specified by Weeks in a Month.
        3. (Optional) Specify Excluded Days in a Month. Backup tasks will not be performed on these dates in each month.
          NOTE:

          You cannot select all dates in Excluded Days in a Month.

        4. Set the Execution Time or Execution Period for backup tasks. The system automatically schedules backup tasks at the specified time. You can click to add multiple time points or periods.
        5. Set or modify the full backup policy as required.
          1. Specify Weeks in a Month. Backup tasks will be performed in these weeks of each month.
          2. Specify Days in a Week. Backup tasks will be performed on these days in each week specified by Weeks in a Month.
          3. (Optional) Specify Excluded Days in a Month. Backup tasks will not be performed on these dates in each month.
            NOTE:

            You cannot select all dates in Excluded Days in a Month.

          4. Set the Execution Time or Execution Period for backup tasks. The system automatically schedules backup tasks at the specified time. You can click to add multiple time points or periods.
        NOTE:
        • If both incremental and full backups are scheduled at the same point in time, the system will execute full backup first.
        • If a backup task has not been completed within the specified period, the next backup task will not be started. The system performs the next backup task after the current task is complete.
        • If the Execution Period is set and the duration of a backup task exceeds the range specified by the Execution Period, the backup task will continue until it is complete. If a backup task is in the To be scheduled state, no more backup task will be executed.
        • A higher backup frequency provides more reliable data protection, but requires a longer time and larger space. Set a proper backup plan based on your reliability requirements and service load.
      • Once

        Modify the execution time for the backup task in Once. Ensure that the execution time is later than the current time of the storage system.

    2. Modify the retention policy parameters for backup images. The retention policy can be By Image Count, By Time, or Permanent.
      • By image count
        NOTE:

        If the current retention policy is By Image Count, you can only modify the parameters of the current retention policy, but cannot change it to another retention policy.

        1. Set the total number of backup images retained for a LUN or LUN consistency group.
          NOTE:

          Once the number of backup images exceeds this value, the system automatically deletes the earliest images (the latest image retained in each year, month, week, or day will not be deleted).

        2. Click Advanced and set the duration for retaining the latest backup image in each year, month, week, or day. To be more specific, for the last xx years, xx months, xx weeks, or xx days from the current time, the latest image in each year, month, week, or day is retained. For example, if the current year is 2018 and you set Retain 3 year(s), latest image in each year, the system will retain the latest images generated in years 2015, 2016, and 2017.
          NOTE:
          • The value range for the total number of retained backup images is 1-100. The default is 90.
          • The value range for the duration of retaining the latest backup image in each year is 0-999. The default is 10.
          • The value range for the duration of retaining the latest backup image in each month is 0-999. The default is 10.
          • The value range for the duration of retaining the latest backup image in each week is 0-9999. The default is 10.
          • The value range for the duration of retaining the latest backup image on each day is 0-99999. The default is 10.
      • By time
        NOTE:

        If the current retention policy is By Time, you can change it to Permanent, but cannot change it to By Image Count.

        Set the retention period.

        NOTE:

        If you set the retention period by day, the value range is 1-9125.

        If you set the retention period by week, the value range is 1-1300.

        If you set the retention period by month, the value range is 1-300.

        If you set the retention period by year, the value range is 1-25.

      • Permanent
        NOTE:

        If the current retention policy is Permanent, you can change it to By Time, but cannot change it to By Image Count.

    3. Modify the Retry Times and Retry Window for failed backup tasks.

      The Retry Window is the maximum time range for retrying failed backup tasks.

      NOTE:
      • The value range for the Retry Times is 1-10.
      • The value range for the Retry Window is 1-168.
      • If all retries fail, and either the retry times or retry window reaches the specified value (whichever occurs first), the system stops retrying the backup task.
      • If a retry succeeds within the window, the system will not perform more retries.

  5. Click OK.

    The Execution Result dialog box is displayed, indicating that the operation is successful.

    NOTE:

    If you do not modify the properties of the backup plan, the Execution Result dialog box will not be displayed. The Properties of Backup Plan dialog box is closed after you click OK.

  6. Click Close.
