Back up on-premises NAS files

Create a backup plan

When you create a backup plan for the first time, a step-by-step guide appears at the top of the new console. This guide walks you through adding a data source, configuring a client group, and creating a backup plan.

1. On the NAS Backup - On-premises NAS page, select a region.

   Note

   If you are using the Legacy Console (the Try New Version button appears at the top of the page), on the NAS Instance tab under Local NAS, click NAS Backup Wizard.

2. Add an on-premises NAS data source.

   1. On the On-premises NAS Data Source tab, click Create Data Source.

   2. In the Create Data Source panel, configure the parameters as described in the following table.

      Parameter	Description
      NAS Instance Name	The name of the NAS instance to back up.
      NAS Network Address	The network address of the NAS instance to back up. Obtain the network address from your NAS administrator. Examples of network addresses include 47.100.XX.XX or nas.company.com.
      NAS Share Path	The path relative to the root directory (/), such as /myshare. This indicates that the /myshare path is shared for subsequent data backups. To query the NAS shared directory, see How do I query the NAS shared directory?. Only uppercase and lowercase English letters, digits, and the special characters ,-_=/.:\ are supported. Note In most cases, the root directory of an Apsara File Storage NAS file system is / when mounted using the NFS protocol, and /myshare when mounted using the SMB protocol. However, the mounted directory may vary in actual operations. Therefore, proceed based on your actual mount configuration.
      Protocol Type	NFS and SMB are supported. Enter the Username and Password required to mount the NAS. If you set Protocol Type to SMB, make sure to enter the correct username and password.

      (Optional) Click Advanced Settings, and then click Set Mount Parameters.

      You can select multiple mount parameters when you mount a file system. The following table describes the mount parameters.

      Parameter	Description
      vers	The file system version. vers=3: Mounts the file system using NFS v3. vers=4: Mounts the file system using NFS v4.
      nolock	Specifies whether to enable file locking.
      proto	The file system mount protocol.
      rsize	Defines the size of the data block for reading data between the client and the file system. Recommended value: 1048576 (bytes).
      wsize	Defines the size of the data block for writing data between the client and the file system. Recommended value: 1048576 (bytes).
      hard	If the File Storage NAS becomes temporarily unavailable, a local application using a file on the file system stops and waits for the file system to come back online. Enable this parameter.
      timeo	The time, in tenths of a second, that the NFS client waits for a response before it retries a request to the file system. Recommended value: 600 (60 seconds).
      retrans	The number of times the NFS client retries a request. Recommended value: 2

   3. Configure a backup client group, and then click OK.

      Select the client where the backup client is installed. You can add multiple clients to a backup client group to run backup tasks concurrently.

      You can select an existing client group or click Create Backup Client Group. When you create a new group, specify a custom Client Group Name and select the clients to add to the group.

      Note

      To avoid public network charges during backup, click Settings in the Actions column for the client. In the Client Settings panel, change Data Network from Internet to VPC and save the settings.

      If you have not installed a client, see Download and activate a Linux client.

3. Add an on-premises NAS backup.

   1. On the Protected On-premises NAS Data Sources tab, click Add On-premises NAS Backup.

   2. In the Create Backup Plan panel, configure the backup plan parameters, and then click OK.

      Important

      • If the region that you selected supports backup policies, you can set up a backup plan only by associating it with a backup policy. Cloud Backup periodically backs up the on-premises NAS based on the backup policy.

      • In the navigation pane on the left, click Policy Center to view the regions that support backup policies. For more information about how to create a backup policy, see Create a backup policy.

      Parameter	Description
      Select Data Source	Select the on-premises NAS data source you added in the previous step. Note This parameter is available only in the new console.
      Source Paths	Enter the directory to back up. You can specify only one directory. Wildcard characters are not supported.
      Backup Rule	Backup rules include the following three types: Include All Files: Backs up all files in the selected source path. Include Files or Exclude Files: After selecting an option, manually enter a file list in the Enter Paths box. Files will be backed up according to the rule. A file list specifies a subpath relative to the source path. The matching rules for the subpath are as follows: If the subpath starts with a forward slash (/), it is matched as a full path under the source path. For example, if the source path is /data/share and the file list is /subdir/data, the files and directories under /data/share/subdir/data are backed up (or excluded). For example, if the source path is /data/share and the file list is /abc*, the files or directories under /data/share/abc that match the prefix abc are backed up (or excluded). If the subpath does not start with a forward slash (/), it is matched as a relative path under the source path. Any subpath that matches the rule will be hit. For example, if the source path is /data/share and the file list is abc*, the files or directories under /data/share that match the prefix abc are backed up (or excluded). For example, if the source path is /data/share and the file list is abc, all files or directories named abc under /data/share are backed up (or excluded).
      Backup Policy	Select a backup policy from the drop-down list. Cloud Backup automatically backs up the data source according to the backup policy you set. A backup policy includes settings such as backup vault encryption, backup interval, retention period, cross-region replication, automatic archiving, and backup point virus scanning to help you flexibly manage your data source assets. If the default backup policy does not meet your needs, click Create Backup Policy or Edit Policy to manage backup policies. For descriptions of the parameters in a backup policy, see Policy Center.

   After the backup plan is created, its Plan Status becomes active, and Cloud Backup runs backup jobs based on the specified start time and backup interval.

View backup jobs

When the scheduled backup time arrives, Cloud Backup starts and runs the backup job.

On the Backup Jobs tab, when the Status of a backup job is Completed, it means the backup was successful. You can view details such as Total Scanned at Source, Backup Completed, Written to Vault, and Backup Speed. For specific metric descriptions, refer to the tooltips in the Cloud Backup console.

For a running task, to cancel a single backup job, click Cancel in the Actions column of the backup job and confirm the cancellation.

Backup status descriptions

Browse backup files

The Browse feature lets you browse backed-up files. If a backup point has been scanned for viruses, Cloud Backup marks any infected files.

1. In the Backup Details section, click Browse in the Actions column of the target backup point.

2. In the Browse panel, view the backed-up on-premises NAS files.

Extend the retention period of a backup point

To keep historical data from on-premises NAS backups for a longer period, you can extend the retention period of the backup points.

1. In the Backup Details section, click the icon in the Expires At column of the target backup point.

2. Set a Schedule Time or select Never Expire, and then click Save.

   After you save the setting, you can view the new expiration time in the Expires At column.

Delete backup data

This section describes how to delete backup point data generated by the backup client.

In the list view of the Backup Details section, you can delete backup points in one of the following ways.

• Delete a single backup point: Click Delete in the Actions column of the target backup point and confirm the deletion.

• Delete in batches: Select the target backup points, click Delete Backup Point below the list, and confirm the deletion.

Run a backup immediately

In the Actions column for the backup plan, choose ┇ > Run Now to start a backup immediately.

Modify a backup plan

1. Click Modify in the Actions column of the backup plan.

2. In the Configure Plan panel, modify configurations such as basic settings and the backup policy as needed.

2. In the Edit NAS Instance dialog box, modify the NAS instance information.

3. Click OK.

Delete an on-premises NAS data source

Click Delete in the Actions column of the NAS instance and confirm the deletion.

Reinstall the backup client

In the Client Operation column, choose ┇ > Reinstall. After the installation is complete, the client status changes to Activated.

Set client parameters

In the Client Operation column, click Client Settings to configure the client parameters. We recommend that you use the default configurations.

Manage client groups

Click Edit Backup Client Group. In the Edit Backup Client Group panel, you can modify the client group name, add clients to the group, or remove clients from the group.

Virus scanning

To prevent files that contain viruses from being restored to the production environment, the Cloud Backup service provides a backup point virus scanning feature. This helps you select clean backup points for data restoration. On the Backup Details tab, in the Backup History section, you can choose ┇ > Virus Detection in the Actions column of a backup point to scan its files for viruses.

Backup vault replication

To mitigate the impact of regional disasters or account management risks on business continuity, Cloud Backup supports configuring cross-region backup or cross-account replication for backup vaults for backup vaults with a Vault Type of General Backup. After configuration, data in the source backup vault is automatically synchronized to the replication target vault, which ensures data consistency between the two locations. You can also perform cross-region data restoration from the replication target vault if necessary.

For general backup vaults that store on-premises NAS files, configuring backup vault replication provides cross-region or cross-account disaster recovery for your data.
