This topic describes how to use Hybrid Backup Recovery (HBR) to back up files in an Isilon (PowerScale) instance.

Prerequisites

Preparations are completed.

Create a backup plan

If you create a backup plan for the first time, we recommend that you use Isilon Backup Wizard to perform a complete backup.

  1. Log on to the HBR console.
  2. In the left-side navigation pane, choose Backup > NAS Backup. On the NAS Backup page, select Isilon (PowerScale).
  3. Click Isilon Backup Wizard in the upper-right corner.
    1. Add an Isilon (PowerScale) instance.
      1. In the Backup Source Isilon step on the Create Backup Plan page, select New Isilon Instance for Backup Isilon Instance.
      2. Set the basic parameters.

        You must set the following parameters: Isilon Instance Name, Isilon Management Username, Isilon Management Password, Isilon Management Address, Isilon Management Port, and Isilon Share Path.

        Isilon Share Path is the path relative to the /ifs folder. Example: /myshare.

        The value of Isilon Share Path can include only letters, numbers, and the following special characters: , - _ = / . : \.

      3. (Optional) Click Show Advanced Settings and then click +Set Mount Parameters.
        You can add multiple mount parameters when you mount a file system. The parameters are separated with commas (,) in the mount command. The following table describes the mount parameters that you can configure.
        Parameter Description
        vers Specifies the protocol version of the file system.
        • vers=3: uses NFSv3 to mount the file system.
        • vers=4: uses NFSv4 to mount the file system.
        nolock Specifies whether to enable file locking.
        proto Specifies the protocol used to mount the file system.
        rsize Specifies the size of data blocks that the client reads from the file system.

        Recommended value: 1048576.

        wsize Specifies the size of data blocks that the client writes to the file system.

        Recommended value: 1048576.

        hard Specifies that applications stop accessing a file system when the file system is unavailable, and wait until the file system is available. We recommend that you configure this parameter.
        timeo Specifies the period in deciseconds (tenths of a second) for which the NFS client waits before it retries to send a request.

        Recommended value: 600 (60 seconds).

        retrans Specifies the number of times for which the NFS client retries a request.

        Recommended value: 2.

      4. Click Next.
    2. Create a client group.
      You can add multiple HBR clients to a client group to concurrently perform a backup job.
      1. Select New Backup Client Group for Backup Clients Group. Specify Client Group Name and select the clients you want to add to the client group.

        You can also click More > Edit Backup Clients Group in the Actions column corresponding to a client group on the Isilon Instance tab to modify or delete the clients included in the client group.

        If you have not installed an HBR client, see Download and activate an HBR client for Linux.

      2. Click Next.
    3. Create a backup plan.
      1. The following table describes the basic parameters that you can configure.
        Parameter Description
        Backup Vault If you have created backup vaults, click Select Vault and select a backup vault from the Vault Name drop-down list. If you have not created backup vaults, click Create Vault and specify Vault Name. The vault name must be 1 to 64 bytes in length.
        Note A backup vault is a repository where HBR stores backup data in the cloud. You can back up files from multiple HBR backup clients to the same vault. Backup vaults reside in different regions. You can select or create a backup vault only in the current region.
        Plan Name The name of the backup plan. By default, a random name is used.
        Source Paths The path from which you want to back up files. You can specify only one path. The path cannot include wildcards.
        Backup Rule You can specify the following three backup rules:
        • Include All Files: All files in the source path are backed up.
        • Include Files or Exclude Files: You must enter the names of the files you want to or do not want to back up in the Enter Paths field. HBR backs up files based on the rule that you specified.

          The file names you enter in the Enter Paths field are equivalent to relative paths to the source path. HBR matches the file names based on the following principles:

          • If a file name specified in the Enter Paths field starts with a forward slash (/), HBR determines that the name is a relative path to the source path and combines the relative path and the source path into a complete path. Files in the complete path are included in or excluded from the backup plan.

            Example 1: If the source path is /ifs/dataset and /subdir/data is entered in the Enter Paths field, files and directories in /ifs/dataset/subdir/data are included in or excluded from the backup plan.

            Example 2: If the source path is /ifs/dataset and /abc* is entered in the Enter Paths field, files and directories whose names are prefixed with abc in /ifs/dataset/abc are included in or excluded from the backup plan.

          • If a file name specified in the Enter Paths field does not start with a forward slash (/), HBR uses the name as a matching condition. All files and directories that match the condition in the source path are included in or excluded from the backup plan.

            Example 1: If the source path is /ifs/dataset and abc* is entered in the Enter Paths field, files and directories whose names are prefixed with abc in /ifs/dataset are included in or excluded from the backup plan.

            Example 2: If the source path is /ifs/dataset and abc is entered in the Enter Path field, files and directories whose names are abc in /ifs/dataset are included in or excluded from the backup plan.

        Start Time The start time of the backup plan. The time is accurate to the second.
        Backup Interval The interval at which the incremental backup is performed. Unit: hours, days, or weeks.
        Retention Policy The retention period of the backup data.
        • Limited: The backup data is stored for a specified period. Unit: days, weeks, months, or years.
        • Permanent: The backup data is permanently stored.
      2. (Optional) Click Show Advanced Settings and configure the parameters described in the following table.
        Parameter Description
        Switch to full backup when incremental backup fails If you turn on this switch, an incremental backup is automatically converted to a full backup when the incremental backup fails. An incremental backup may fail because of the following reasons:
        • The backup rule that includes files in or excludes files from the backup plan is modified.
        • Data that is last backed up to the backup vault expires.
        • The snapshot that is last created for the Isilon (PowerScale) instance is deleted.
        Backup Sub-task Slice Size You can add multiple HBR clients into a backup client group to concurrently perform a backup job. If you configure this parameter, the number of files backed up by a client is larger than or equal to the value of this parameter.
      3. Click OK.

        After the backup plan is created, you can view the progress of the backup job on the Backup Jobs tab.

      To create more backup plans for the Isilon instance, we recommend that you click New Backup Plan in the Actions column corresponding to the instance on the Isilon Instance tab.
