This operation allows you to view the information (such as the basic information and pair information) about existing HyperVault pairs to monitor the HyperVault status.

Prerequisites

At least one HyperVault pair has been created.

Procedure
  1. Log in to DeviceManager.
  2. Choose Data Protection > HyperVault > HyperVault.

    Backup Speed

    Backup rate

    [Value range]

    Possible values are Low, Medium, High, or Highest.

    NOTE:
    • Set the rate to Low or Medium when service load is heavy on the storage system.

    [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

    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]

Modifying HyperVault Properties

This operation enables you to modify HyperVault properties to meet service needs.

Prerequisites

A HyperVault pair has been created.

Procedure
  1. Log in to DeviceManager.
  2. Choose Data Protection > HyperVault > HyperVault.
  3. Select the HyperVault pair that you want to modify and click Properties.

    The HyperVault Properties dialog box is displayed.

  4. Modify the HyperVault pair parameters, such as whether to enable remote backup, the backup speed, recovery policy, and remote recovery speed.

    NOTE:
    • Set the backup speed to Low or Medium when service load is heavy on the storage system. Set the backup speed to High or Highest when service load is light on the storage system.
    • You can choose whether to enable remote backup only for a HyperVault task that has not been assigned a remote file system. After you enable remote backup and click OK, the system immediately starts initial synchronization.

  5. Click OK.

    The Execution Result dialog box is displayed.

    Click Close.

Performing a Manual Backup

You can perform a backup manually to obtain a data copy immediately.

Prerequisites
  • A HyperVault pair has been created, and it is in the normal, interrupted, or to-be-recovered state.
  • At least a local backup policy or remote back policy has been configured.
Procedure
  1. Log in to DeviceManager.
  2. Choose Data Protection > HyperVault > HyperVault.
  3. Select the desired HyperVault pair and click Manual Backup.

    The Manual Backup dialog box is displayed.

  4. Set the backup type, backup policy, the user-defined name of the backup copy. Then click OK.

    The Execution Result dialog box is displayed.

  5. Click Close.

Recovering Data Using Local or Remote Backup Copies

If data on the local file system is damaged, use a local or remote backup copy to recover it.

Prerequisites
  • A HyperVault pair has been created.
  • File system sharing has been stopped before local or remote recovery is executed. More than half of the total free space in the source file system must be reserved for remote recovery (applicable to versions earlier than V300R006C10).
  • At least one local or remote backup copy exists.
NOTE:

To check for existing backup copies, choose Data Protection > HyperVault > HyperVault. On the Backup Copy tab in the lower pane, check whether there are backup copies whose Recoverable is Yes.

Context

The storage system provides two recovery modes:

  • Local recovery: File systems are recovered by rolling back local backup snapshots.
  • Remote recovery: The recovery is performed using a snapshot saved on the backup storage system.

If an exception occurs on the source storage system, local recovery is attempted first with an available local snapshot. If no local snapshots are available or the data that needs to be recovered is not saved locally, remote recovery is performed with a qualified remote snapshot.

Procedure
  1. Log in to DeviceManager.
  2. Choose Data Protection > HyperVault > HyperVault.
  3. Select the desired HyperVault pair and click Recover.

    The Recover dialog box is displayed.

  4. Select the backup copy that you want to use for data recovery and click OK.

    The security alert dialog box is displayed.

  5. Optional: If you select Clean Up the Primary File System, all data and snapshots in the source file system are deleted during remote recovery.

    NOTE:

    If you are starting the recovery task on the backup storage system and the percentage of the source file system's remaining space is lower than 50%, you are advised to select this option.

  6. Confirm the information in the dialog box and select I have read and understand the consequences associated with performing this operation.
  7. Click OK.

    The Success dialog box is displayed, indicating that the operation succeeded.

    Click OK.

Deleting a HyperVault Pair

This operation allows you to delete a HyperVault pair that is no longer needed.

Prerequisites
  • A HyperVault pair has been created, and the pair does not contain any local or remote backup policy.
  • The HyperVault pair to be deleted has no running job.
Procedure
  1. Log in to DeviceManager.
  2. Choose Data Protection > HyperVault > HyperVault.
  3. Select the HyperVault pair that you want to delete and click Delete.

    The security alert dialog box is displayed.

  4. In the security alert dialog box, select Local deletion is allowed when configured links are disconnected or HyperVault pairs are faulty based on your needs.
  5. Confirm the information in the dialog box and select I have read and understand the consequences associated with performing this operation.

    The Execution Result dialog box is displayed.

    Click Close.
