You must add a data source the first time you archive data. The following data sources are supported: on-premises NAS file systems, Isilon (PowerScale) NAS file systems, Hadoop Distributed File System (HDFS) file systems, and S3-Compatible Storage buckets. This topic describes how to use Cloud Backup to add a data source for archiving.
Procedure
Log on to the Cloud Backup console.
In the left-side navigation pane, click Archive.
In the top navigation bar, select a region.
On the Analyze and Archive tab, click Create Data Source.
In the Create Data Source panel, configure the parameters and click Next.
Source Type: Local NAS
Configure the parameters described in the following table.
Parameter | Description |
Source Type | The type of the data source. Select Local NAS. |
Data Source Name | Enter a name for the data source that you want to add. |
NAS Type | The type of the NAS file system. Valid values: |
NAS Management Username | This parameter is required only if you set the NAS Type parameter to Isilon (PowerScale). This parameter specifies the username of the account that is used to manage the NAS file system. |
NAS Management Password | This parameter is required only if you set the NAS Type parameter to Isilon (PowerScale). This parameter specifies the password of the account. |
NAS Network Address | The network address of the NAS file system. |
NAS Management Port | This parameter is required only if you set the NAS Type parameter to Isilon (PowerScale). This parameter specifies the number of the port that is used to manage the NAS file system. |
NAS Share Path | The name of the NAS directory from which you want to archive data. The name can contain letters, digits, and the following special characters: , - _ = / . : \ . If you set the NAS Type parameter to Isilon (PowerScale), the directory is relative to the /ifs directory. For example, if you enter /myshare, Cloud Backup archives data from the /ifs/myshare directory. If you set the NAS Type parameter to Other NAS, the directory is relative to the / root directory. For example, if you enter /myshare, Cloud Backup archives data from the /myshare directory.
|
Protocol Type | The protocol type of the NAS file system. Valid values:
Important If you want to archive data from a File Storage NAS file system, configure the vers parameter in the Advanced Settings section. |
Optional. Click Advanced Settings and then click +Set Mount Parameters.
The following table describes the mount parameters that you can configure.
Parameter | Description |
vers | 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. vers=4.0: uses NFSv4.0 to mount the file system.
|
nolock | Specifies whether to enable file locking. |
proto | The protocol that you want to use to mount the file system. |
rsize | The size of each data block that a client can read from the file system. Recommended value: 1048576. Unit: bytes. |
wsize | The size of each data block that a client can write to the file system. Recommended value: 1048576. Unit: bytes. |
hard | Specifies that applications no longer access the file system when the file system is unavailable and access the file system again when the file system becomes available. We recommend that you enable this parameter. |
timeo | The period of time for which the NFS client waits before the client retries to send a request. Unit: deciseconds (tenths of a second). Recommended value: 600 (60 seconds). |
retrans | The number of retries after the NFS client fails to send a request. Recommended value: 2. |
noresvport | Specifies that a new TCP port is used to ensure network continuity between the file system and the ECS instance when the network recovers from a failure. We recommend that you enable this parameter. |
Source Type: HDFS
Configure the parameters described in the following table.
Parameter | Description |
Source Type | The type of the data source. Select HDFS. |
Data Source Name | The name of the HDFS data source. You can specify a name based on your business requirements. Example: back-end-hdfs. |
NameNode Network Address | The network address of an HDFS primary server. NameNode serves as a primary server that is used to manage the namespaces of HDFS file systems and control access from clients to files in the file systems. |
NameNode Port | The port number of the HDFS primary server. |
Secondary NameNode Network Address | The network address of a secondary HDFS node. A secondary HDFS node helps the primary server perform management tasks. |
Secondary NameNode Port | The port number of the secondary HDFS node. |
HDFS Username | The name of the HDFS user.
Note Make sure that the specified HDFS user has sufficient permissions. Otherwise, you may be unable to read files when you archive data, write files when you retrieve data, or restore the information of user groups. We recommend that you set this parameter to hadoop or hdfs. |
Source Type: S3
Configure the parameters described in the following table.
Parameter | Description |
Source Type | The type of the data source. Select S3. |
Data Source Name | The name of the S3 data source. You can specify a name based on your business requirements. Example: awss3. |
Use HTTPS | Specifies whether to encrypt transmitted data by using HTTPS. Valid values: |
S3 Bucket | The name of the S3-Compatible Storage bucket. |
S3 Endpoint | The endpoint of the bucket that can be used to perform operations on S3 objects. Examples: s3.us-east-1.amazonaws.com and 11.238.XXX.XXX:9000. |
Access Key | The key ID that is used to access the S3-Compatible Storage bucket. |
Secret Key | The access key that is used to access the S3-Compatible Storage bucket. |
Associate a client group and click Next.
You can add multiple clients to a client group to concurrently run an archive job. You can also select an existing client group. In this example, set the Client Group From parameter to Create Backup Client Group. Then, enter a name for Client Group Name and select the clients that you want to add to the client group.
Configure a data analysis plan and click OK.
In the Configure Analysis Plan step, configure the parameters. The following table describes the parameters.
Parameter | Description |
Enable Data Source Analysis | Specifies whether to enable the data analysis feature. If you turn on Enable Data Source Analysis, Cloud Backup analyzes data after the data source is added. You can use Cloud Backup to scan, analyze, or search for a data source only if the data analysis feature is enabled for the data source.
Note If you turn off Enable Data Source Analysis, Cloud Backup directly archives data from the data source. |
Meta Index Start Time | The time when Cloud Backup starts to perform an index operation on metadata. |
Meta Index Interval | The interval at which Cloud Backup performs index operations on metadata. Unit: days or weeks. |
After you add a data source, the data source is displayed on the Analyze and Archive tab.
Related operations
After a data source is added, you can click More in the Actions column and then select the required operation. The following table describes the available operations.
Operation | Description |
Configure Analysis Plan | Configures a data analysis plan for the data source. |
Run Meta Indexing | Creates an index for the data source. This way, you can efficiently analyze and search for data. |
View Data Source | Views the details of the data source. The details include the type, NAS network address, NAS share path, and backup client group. |
Edit Data Source | Modifies the parameters of the data source. |
Unregister Data Source | Unregisters a data source. If you no longer require an archive plan, you can perform this operation. |
Edit Backup Client Group | Changes the name of a client or a client group. |
