Creating a HyperVault Policy in the Non-tenant Scenario

Creating a HyperVault Policy in the Non-tenant Scenario

In the non-tenant scenario, set up a pair between the local and the remote file system and create a HyperVault policy for the storage system to provide flexible and reliable data protection.

Prerequisites

  • Both the source and backup storage systems are working properly, and file systems have been created at both ends.
  • The remote file system has a capacity greater than or equal to that of the local file system. The remote file system is newly created and not shared, and no data has been written to it.
  • For details about restrictions on the primary and secondary file systems used to create a HyperVault pair, see Impact and Restrictions.

Context

  • A pair is the data replication relationship between the file systems in the source and backup storage systems. When HyperVault is configured, a file system in the source storage system and a file system in the backup storage system form a pair. Data is only copied from the source file system to the backup file system through a replication link.
  • A backup policy supports a maximum of four local and four remote scheduled backup policies.

Procedure

  1. Choose Data Protection > HyperVault > HyperVault.
  2. Click Create.

    The Create HyperVault Pair Wizard is displayed.

  3. Select the source file system whose data needs to be backed up and click Next.
  4. Optional: Configure a local backup policy.

    1. Click Create.

      The Create Local Backup Policy dialog box is displayed.

    2. Configure the parameters of the policy and click OK.

      Table 3-8 describes related parameters.

      Table 3-8 Parameters of a local backup policy

      Parameter

      Description

      Value

      Name

      Name of a local backup policy

      [Value range]

      • Must be unique.
      • Contains only letters, digits, underscores (_), periods (.), and hyphens (-).
      • Contains 1 to 127 characters.

      [Example]

      localPolicy001

      Backup Copy Threshold

      Maximum number of copies retained. If the number is exceeded, the earliest copy will be deleted automatically.

      [Value range]

      3 to 256

      [Example]

      3

      Backup Period

      Execution period of a local backup policy

      [Value range]

      Possible values are as follows: By Day, Every Week, or Every Month.

      [Example]

      Every Week

      Backup Time

      Execution time of a local backup policy

      [Value range]

      The minimum backup interval is five minutes. In addition, you can specify a point in time for data backup.

      [Example]

      Executed at 00:00.

    3. On page Configure Local Backup Policy, click Next.

  5. Optional: Configure a remote backup policy and click Next.

    Table 3-9 describes related parameters.

    NOTE:

    If you skip this step, you can add remote backup parameters by modifying the properties of the HyperVault pair.

    Table 3-9 Parameters of a remote backup policy

    Parameter

    Description

    Value

    Enable remote backup

    Select Enable remote backup to configure the following parameters.

    NOTE:

    This parameter is available after you create a local backup policy.

    [Example]

    Enable remote backup

    Remote File System

    File system at the backup end

    NOTE:

    If no remote device is connected, you must add a remote device first.

    [Example]

    -

    Backup Speed

    Speed of remote backup

    [Value range]

    Possible values are as follows: Low, Medium, High, or Highest.

    • Low: The speed is normally from 0 MB/s to 5 MB/s. Synchronization will take a long time. This value is applicable to scenarios where the service load is heavy.
    • Medium: The speed is normally from 10 MB/s to 20 MB/s. Synchronization will take relatively short period. This value is applicable to scenarios where the service load is heavy.
    • High: The speed is normally from 50 MB/s to 70 MB/s. Synchronization will take a short period. This value is applicable to scenarios where the service load is relatively light.
    • Highest: The speed is normally above 100 MB/s. Synchronization will be completed in the shortest period. This value is applicable to scenarios where the service load is light.

    [Example]

    Medium

    Recovery Policy

    Backup recovery policy used when the storage system fails

    [Value range]

    Possible values are Automatic or Manual.

    • Manual: You need to recover a backup policy manually after the link is restored. The source and backup ends are in the to-be-recovered state, and data will not be automatically backed up from the source end.
    • Automatic: The system recovers a backup policy and backs up data from the source end automatically after the link is restored.

    [Example]

    Automatic

    Data Transmission

    You can determine whether data is compressed before it is transmitted by setting this parameter. If data is compressed before being transmitted, the bandwidth used by backup links will be reduced and replication performance will be improved.

    [Value range]

    Possible values are Compression or No compression.

    [Example]

    Compression

    Remote Recovery Speed

    Speed of remote recovery

    [Value range]

    Possible values are High or Highest.

    • High: The rate is generally from 50 MB/s to 70 MB/s, depending on the I/O model.
    • Highest: The rate is generally above 100 MB/s, depending on the I/O model.

    [Example]

    High

    Initial backup

    Determines whether to perform an initial backup after a HyperVault pair is created. You are advised to implement the initial backup to ensure consistency between the source and backup file systems.

    [Example]

    Initial backup

    Name

    Name of a remote backup policy

    NOTE:

    Click Create and set the remote backup policy in the displayed dialog box. You can set four remote backup policies at most.

    [Value range]

    • Must be unique.
    • Contains only letters, digits, underscores (_), periods (.), and hyphens (-).
    • Contains 1 to 127 characters.

    [Example]

    remotePolicy001

    Backup Copy Threshold

    Maximum number of remote file system copies retained. If the number is exceeded, the earliest copy will be deleted automatically.

    [Value range]

    3 to 256
