Back up a CPFS

Create a backup plan

1. On the CPFS Backup page, click the Protected CPFS data sources tab, and then click Add CPFS backup.

   Note

   If you are using the classic console (the Try New Version button is displayed in the upper-right corner), on the Data Source List tab, find the target CPFS data source and click Create Backup Plan in the Actions column.

2. In the Create Backup Plan panel, configure the following parameters:

   Parameter	Description
   Select Data Source	Select the CPFS data source that you want to back up. 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. The path must be relative to the Data Source Path. Use / to back up the entire directory.
   Backup Rule	Select a backup rule: Include All Files: Backs up all files in the selected path. This rule is suitable for backing up an entire directory. Include Files: Backs up only the specified files. This rule is suitable for scenarios where you need to back up only a few important files. Exclude Files: Excludes the specified files from the backup. This rule is suitable for scenarios where you need to exclude temporary files such as logs and caches. Note These rules are mutually exclusive. If you select Include Files or Exclude Files, enter one file path per line in the Enter Paths field. The path matching rules are as follows: If a path starts with a forward slash (/), the system filters files based on the full path within the source path. If a path does not start with a forward slash (/), the system filters files based on the relative path within the source path. Any subdirectory that matches the rule is affected. Warning If a file matches both an inclusion rule and an exclusion rule, the file is not backed up.
   Backup Policy	Select a backup policy from the drop-down list. Cloud Backup automatically backs up your data source based on the specified backup policy. A backup policy defines key settings such as backup vault encryption, backup interval, retention period, cross-region backup, and automatic archiving. If the default backup policies do not meet your requirements, click Create Backup Policy or Edit Policy to manage backup policies. For more information about the parameters in a backup policy, see Policy center.

Backup status

Verify backup success

After a backup job is complete, you can verify that it was successful in the following ways:

1. In the backup task list, check whether the task status is "Completed".

2. In the Backup History, verify that a new backup point exists and its size is as expected.

3. (Optional) Use the Browse feature to view the files in the backup point and confirm that your critical files were successfully backed up.

View backup jobs

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

On the Backup jobs tab, a backup is successful if its Status is Completed. You can view detailed information about the job, such as Total scanned at source, Total data backed up, Data written to vault, and Backup speed. For descriptions of these metrics, refer to the tooltips in the Cloud Backup console.

To cancel an in-progress backup job, click Cancel in the Actions column for the job and confirm the cancellation.

Browse backup files

You can use the Browse feature to view backed-up files.

1. In the Backup History, find the target backup point and click Browse in the Actions column.

   Alternatively, you can click the icon on the right side of the backup history to switch the display mode, click the target backup point, and then select Browse.

2. In the Browse panel, view the backed-up CPFS files.

Extend backup point retention

You can extend the retention period of a backup point to keep the backup data longer.

1. In the Backup History, click the icon in the Expires At column for the target backup point.

   Alternatively, you can click the icon on the right side of the backup history to switch the display mode, click the target backup point, and then click the icon next to Expires At.

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

   The new expiration time appears in the Expires At column.

Delete backup data

Delete the backup point data generated by the backup client.

In the list mode of the Backup History, use one of the following methods to delete a backup point:

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

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

Alternatively, you can click the icon on the right side of the backup history to switch the display mode, click the target backup point, and then select Delete.

Run an immediate backup

In the Actions column of the backup plan, select ┇ > 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 the basic settings and backup policy as needed.

3. Click OK.

Pause or resume backup plan

Backup plans are enabled by default. If you need to stop data backups for a specific period, you can pause the backup plan and then resume it later.

• Pause a backup plan: Turn off the switch in the Plan Status column or select ┇ > Suspend Plan in the Actions column, and then confirm the pause.

  When a backup plan is paused, subsequent backup jobs will not run. Existing backup points remain and expire based on their configured retention period. However, if the "Retain at least one backup version" setting is enabled, the last backup version is not affected by the retention period. Billing for the CPFS data source continues as long as it has backup points.

• Resume a backup plan: After a backup plan is paused, turn on the switch in the Plan Status column or select ┇ > Resume Plan in the Actions column.

Delete backup plan

If a resource no longer requires periodic backups, you can delete its backup plan.

In the Actions column of the backup plan, select ┇ > Delete Plan, and then confirm the deletion.

Reinstall backup client

To the right of Client Operation, select ┇ > Reinstall. After installation, the client status changes to Activated.

Configure client parameters

To the right of Client Operation, click Client Settings, configure the client parameters, and save the settings. We recommend that you use the default configuration.

Adjust client group

Adjust a client group to add or remove clients.

1. On the backup details page, find and click the Adjust client group button next to Number of clients.

2. In the dialog box that appears, select the clients to add to the client group, or deselect clients to remove.

3. Click OK to save the settings.

Backup vault replication

To prevent regional disasters or account management risks from affecting business continuity, Cloud Backup supports configuring cross-region backup or cross-account backup vault replication for backup vaults whose Storage Vault Type is General-purpose Backup. After configuration, data in the source backup vault is automatically synchronized to the destination backup vault to ensure data consistency between the two locations. Additionally, you can perform cross-region data recovery from the destination backup vault as needed.

For general-purpose backup vaults that store CPFS data, you can configure backup vault replication to achieve cross-region or cross-account disaster recovery protection.

In addition, CPFS backup supports enterprise-grade features such as cross-account backup, automatic archiving, KMS encryption, and immutable backup.
