Cloud Backup:Add a Data Source

Procedure

1. Log on to the Cloud Backup console.

2. In the navigation pane on the left, click Archive.

3. In the top navigation bar, select a region.

4. On the Analyze and Archive tab, click Create Data Source.

5. In the Create Data Source panel, configure the following parameters and click Next.

   • Set Source Type to Local NAS .

     1. Configure the following important parameters:

        Parameter	Description
        Source Type	The type of data source. Select Local NAS.
        Data Source Name	The name of the data source to add.
        NAS Type	The type of NAS. Select Other NAS.
        NAS Network Address	The network address of the NAS to archive.
        NAS Share Path	The shared directory on the NAS. Only uppercase and lowercase letters, digits, and the special characters ,-_=/.:\ are supported. If NAS Type is set to Other NAS, specify the path relative to the / root directory. For example, /myshare means that the /myshare path is shared for archiving.
        Protocol Type	The supported NAS protocol types. NFS: Select this option if the NAS uses the NFS protocol. SMB: Select this option if the NAS uses the SMB protocol. Important If you mount Alibaba Cloud NAS, set the vers parameter in Advanced Settings.

     2. (Optional) Click Advanced Settings, and then click + Configure Mount Parameters .

        The following table describes the mount parameters.

        Parameter	Description
        vers	The file system version. vers=3: Mount the file system using the NFS v3 protocol. vers=4: Mount the file system using the NFS v4 protocol. vers=4.0: Mount the file system using the NFS v4.0 protocol. Note Each version of File Storage NAS differs in features, security, and namespace. For more information, see Differences between NFSv3 and NFSv4.0.
        nolock	Whether to enable file locking.
        proto	The file system mount protocol.
        rsize	The size of data blocks used to read data between the client and the file system. Recommended value: 1048576 bytes
        wsize	The size of data blocks used to write data between the client and the file system. Recommended value: 1048576 bytes
        hard	If the File Storage NAS becomes temporarily unavailable, applications that access files on the file system stop and wait until the file system comes back online. We recommend that you enable this parameter.
        timeo	The timeout period, in units of 0.1 seconds. This is the time that the NFS client waits for a response before retrying a request to the file system. Recommended value: 600 (60 seconds)
        retrans	The number of times that the NFS client retries a request. Recommended value: 2
        noresvport	Use a new TCP port when reconnecting to prevent connection interruptions after network failures. We recommend that you enable this parameter.

   • Set Source Type to HDFS .

     Configure the parameters described in the following table.

     Parameter	Description
     Source Type	The type of data source. Select HDFS.
     Data Source Name	The name of the HDFS data source. Define a suitable name based on your needs. For example, back-end-hdfs.
     NameNode Network Address	The network address of the HDFS primary server. The NameNode acts as the primary server and manages the namespace of the HDFS file system and client access to files.
     NameNode Port	The port number of the HDFS primary server.
     Secondary NameNode Network Address	The network address of the HDFS secondary node. The secondary node helps manage the primary server.
     Secondary NameNode Port	The port number of the HDFS secondary node.
     HDFS Username	The username for HDFS. Note Make sure the HDFS user has sufficient permissions. We recommend that you use hadoop or hdfs. Otherwise, archiving may fail due to insufficient read permissions, or file restoration may fail due to insufficient write permissions or inability to restore group information.

   • Set Source Type to S3.

     The important parameters are described as follows:

     Parameter	Description
     Source Type	The type of data source. Select S3.
     Data Source Name	The name of the S3 data source. Define a suitable name based on your needs. For example, awss3.
     Use HTTPS	Data transferred over HTTPS is encrypted. Do not use Use
     S3 Bucket	The name of the S3 bucket.
     S3 Endpoint	An S3 endpoint is a named network endpoint that connects to a bucket for performing S3 object operations. Examples: s3.us-east-1.amazonaws.com, 11.238.XXX.XXX:9000.
     Access Key	The key ID used to access S3.
     Secret Key	The secret key used to access S3.

6. Associate the data source with a client group and then click Next .

   A client group contains multiple clients and lets you run a concurrent archive task. You can select an existing client group. To create a new client group, set Client Group Source to Create Backup Client Group, enter a Client Group Name, and select the clients that you want to add to the group.

7. Configure a schedule for data analysis and then click OK .

   On the Configure Analysis Plan tab, configure the following parameters.

   Parameter	Description
   Enable Data Source Analysis	Whether to enable data analysis. Turn on Enable Data Source Analysis. Then Cloud Backup starts data analysis after adding the data source. You must enable data analysis to scan, analyze, and search the data source. Note You can archive data directly without enabling data analysis.
   Meta Index Start Time	The start time for metadata indexing.
   Meta Index Interval	The interval at which metadata indexing runs. Units: days or weeks.

   After you add the data source, it appears in the data source list on the Analyze and Archive tab.
