Back up data

Prerequisites

• Activated the Cloud Backup service. Activating Cloud Backup is free, but using the backup features of Cloud Backup incurs Cloud Backup storage fees. For more information, see Billing

• Verified that your Cloud Parallel File Storage (CPFS) file system can reach Alibaba Cloud over the Internet. If Internet access is unavailable, connect the CPFS file system to an Alibaba Cloud virtual private cloud (VPC) through a leased line or VPN. The required routes for on-premises to cloud connections are 100.64.0.0/10 or 100.64.0.0/11 and 100.96.0.0/11. For more information, see Connect a VPC to a data center (single-tunnel mode)

• Install the backup client on the machine that runs the backup jobs. For more information, see Install a backup client.

• Add a CPFS data source in the Cloud Backup console. For more information, see Add a data source.

Usage notes

The backup and restoration rates for Cloud Backup are based on data from a lab environment and are for reference only. For more information, see File backup and restoration rates.

Create a backup plan

1. Log on to the Cloud Backup console.

2. In the left navigation pane, choose Backup > CPFS Backup.

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

4. On the CPFS Backup page, for the target data source, click Create Backup Plan in the Actions column.

5. In the Create Backup Plan panel, configure the following parameters.

   Parameter	Description
   Source Paths	Enter the path of the directory to back up. Only one directory is supported; wildcard characters are not supported. The path must be relative to the Data Source Path. Use / to back up the entire directory.
   Backup Rule	Select one of the following options: Include All Files: Backs up all files in the source path. Include Files or Exclude Files: Enter a file list in the Enter Paths field. Cloud Backup backs up or skips the specified files under the source path. The file list is a subpath of the source path. Path matching works as follows: If the subpath starts with a forward slash (/), the filter matches the full path under the source path. For example, if the source path is /ifs/dataset and the file list is /subdir/data, Cloud Backup targets files and directories at /ifs/dataset/subdir/data. If the source path is /ifs/dataset and the file list is /abc*, Cloud Backup targets files and directories at /ifs/dataset/abc with the prefix abc. If the subpath does not start with a forward slash (/), the filter matches any relative path under the source path. For example, if the source path is /ifs/dataset and the file list is abc*, Cloud Backup targets any file or directory under /ifs/dataset with the prefix abc. If the source path is /ifs/dataset and the file list is abc, Cloud Backup targets all files and directories named abc anywhere under /ifs/dataset.
   Backup Policy	Select a backup policy from the drop-down list. Cloud Backup runs backup jobs automatically based on the selected backup policy. A backup policy defines settings such as backup vault encryption, backup interval, retention period, cross-region replication policy, and automatic data archiving. If the default backup policy does not meet your needs, click Create Backup Policy or Edit Policy. For details on each policy parameter, see Policy center.
   Switch to full backup when incremental backup fails	When enabled, the system automatically runs a full backup if an incremental backup fails. An incremental backup fails when: The include or exclude filter rules are modified. The previous backup data in the backup vault has expired.
   Backup Sub-task Slice Size	When you use a backup client group with multiple clients running backup jobs concurrently, this setting defines the minimum number of files allocated to each client.

After the plan is created, its Plan Status is enabled, and Cloud Backup runs backup jobs at the specified start time and backup interval.

After a successful backup

When the scheduled time arrives, Cloud Backup starts the backup job. The backup is complete when the job Status is Completed.

You can view each backup record in the Backup History. Each successful backup creates a recovery point, which you can use to restore files. For more information, see Restore data.

On the backup history timeline, click a completed recovery point to view details such as its completion time, expiration time, and backup size. You can also click Browse to view its contents.

Troubleshooting

If a backup plan or backup job has an abnormal Status, refer to the following suggestions.

• Follow the prompts on the UI to verify and correct your configuration.

• Backup Jobs Status: Failed (The client does not exist. Check whether the client is uninstalled or whether the ECS instance is released.).

  1. Verify that the backup directory mounted on the CPFS file system is correctly configured.

  2. The backup client group does not contain a backup client, or a required tool is not installed. Reconfigure the backup client. For more information, see Install a backup client.

     Note

     The default client installation paths are for reference only. Use the actual installation paths in your operations.

     • Windows log path: Local Disk (C) > Program Files > Aliyun Hybrid Backup Service Client > logs

     • Linux log path: /opt/alibabacloud/hbrclient/logs

• The Status of the Backup Plans is Paused.

  This backup plan has been suspended. As a result, Cloud Backup will no longer provide backup protection. We recommend that you enable the backup plan as soon as possible.

• If you need more help, contact Online Technical Support. Provide the backup plan ID, region, data source type, and job ID. Also, provide a detailed description of the issue, including the steps that led to the problem and the expected outcome.
