Back up ECS files

Create a backup plan

1. At the top of the ECS File Backup page, select the region of the ECS instance to back up, and then click Add ECS File Backup.

   Note

   If you are using the Legacy Console (identified by Try New Version in the upper-right corner), go to the ECS Instances tab, find the target instance, and click Back Up in the Actions column.

2. In the Create Backup Plan panel, configure the parameters described in the following table.

   Parameter	Description
   ECS To Back Up	Select the ECS instances that you want to back up. You can select multiple ECS instances to create backup plans in batches. Note If you are using the Legacy Console, this parameter is automatically determined by the selected ECS instance and does not need to be configured.
   Backup Folder Rule	Specify the directories to back up. Cloud Backup backs up all files and subdirectories in the specified directories. Select All Folders or Specified Folders. If you select All Folders, select whether to enable Exclude System Folders. If you enable Exclude System Folders, the excluded system directories for Windows and Linux are not included in the backup plan. You can click the icon to the right of Exclude System Folders to obtain the details of the excluded system directories. If you do not enable Exclude System Folders, all directories are included in the backup plan. If you select Specified Folders, you must specify Source Paths. Click Add Folder to specify multiple backup directories. The backup path rules are as follows: Without a wildcard character (*), you can enter up to eight paths. If you use a wildcard character (*), you can enter only one path. Wildcard characters such as /*/* are supported. Each line must be an absolute path, starting with /, \\, C:\, or D:\. When you use VSS, multiple paths, UNC paths, wildcard characters, and file exclusions are not supported. When you use UNC, VSS, wildcard characters, and file exclusions are not supported. When the backup source contains a UNC path, Windows ACLs are not backed up.
   Backup File Type	Select All Types or Specified Type. If you select All Types, all file types are backed up, regardless of the file extension. If you select Specified Type, you must specify the file types to back up in the Select File Type box.
   Backup Policy	Select a backup policy from the drop-down list. Cloud Backup automatically backs up data sources based on the backup policy you set. A backup policy includes settings such as backup vault encryption, backup interval, retention period, geo-redundancy replication policy, automatic backup archiving, and backup point virus scan. These settings help you flexibly manage your data source assets. If the default backup policy does not meet your backup requirements, you can click Create Backup Policy or Edit Policy to manage backup policies. For more information about the parameters in backup policies, see Policy Center.
   Use VSS	Specifies whether to use the Volume Shadow Copy Service (VSS) feature of Windows to accelerate backups. This feature is available only for Windows operating systems. Note When you use VSS, you cannot back up multiple paths or UNC paths, use wildcard characters, or exclude files. To use VSS, turn on the Use VSS switch.
   Enable Bandwidth Throttling	Traffic shaping helps you control backup traffic during peak business hours to avoid affecting normal business operations. To use traffic shaping, turn on the Enable Bandwidth Throttling switch. Select a Time Range (Hour) as needed, enter the Max Bandwidth (MByte/s) for backups within the time window, and then click Add.

3. Click OK to complete the configuration.

Backup running status

View backup jobs

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

On the Backup Jobs tab, a Status of Completed indicates that the backup job was successful. You can view details such as Total Scanned Data at Source, Backed Up Data, Data Written to Vault, and Backup Speed. For a description of each metric, refer to the tooltips in the Cloud Backup console.

To cancel a one-time backup job that is in progress, click Cancel in the Actions column and confirm the action.

Browse backup files

You can use the Browse feature to view backed-up files. If a backup point has been scanned for viruses, Cloud Backup marks any infected files.

1. In the Backup History section, click Browse in the Actions column for the target backup point.

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

2. In the Browse panel, you can view the backed-up ECS files.

Extend the retention period of a backup point

To keep ECS file backup data for a longer time, you can extend the retention period of a backup point.

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

   You can also click the icon on the right side of the backup history to switch the display mode. Then, click the target backup point and then the icon to the right of Expires At.

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

   After the configuration is complete, the new expiration time is displayed in the Expires At column.

Delete backups

This section describes how to delete backup points created by the backup client.

To delete backup points from the Backup History section in list view, use one of the following methods.

• To delete a single backup point, find the target backup point, click Delete in the Actions column, and then confirm the deletion.

• To delete backup points in batches, select the target backup points, click Delete Backup Point below the list, and then confirm the deletion.

Alternatively, click the icon to the right of the backup history to switch the display mode. Then, click the target backup point and select Delete.

Run a backup job immediately

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

Modify a backup plan

1. In the Actions column, click Modify for the backup plan.

2. In the Configure Plan panel, you can modify the basic settings, backup policies, and other configurations as needed.

3. Click OK.

Pause or resume a backup plan

Backup plans are enabled by default. To stop data backups for a specific period, you can pause the backup plan. You can then resume the plan when you need to back up data again.

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

  After a backup plan is paused, subsequent backup jobs will not run. Existing backup points are not affected and will expire automatically based on the set retention period. If "Keep at least one backup version" is enabled, the last backup version is not affected by the retention period. Billing for the ECS instance continues as long as backup points exist.

• Resume backup plan: You can turn on the switch in the Plan Status column or select ┇ > Resume Plan in the Actions column.

Delete a backup plan

Select ┇ > Delete Plan in the Actions column of the backup plan, and confirm the deletion.

Reinstall the backup client

To the right of Client Operation, click ┇ > Reinstall. After the reinstallation is complete, the client status changes to Activated.

If the client status is abnormal, see Troubleshoot and handle abnormal file backup client status, How to check the running status of the Cloud Backup client, and How to view the default installation path and logs of the Cloud Backup client for troubleshooting.

Set client parameters

Next to Client Operation, click Client Settings. Configure the client parameters and save the settings. We recommend using the default configurations.

Set retry parameters

If a file backup fails due to factors such as network instability, you can configure retry parameters.

1. Log on to the server whose files need to be backed up.

2. Switch to the default installation directory of the Cloud Backup client.

3. In the client folder, create a file named hbr.config.

   Note

   The hbr.config file is at the same level as the hbrclient and ids executables.

4. Add the following parameters to the hbr.config file.

   Parameter	Description
   retry_times	For client versions 2.16.0 and later, this is the number of retry attempts for data backup. The default is 30.
   retry_interval	For client versions 2.16.0 and later, this is the retry interval for data backup. The default is 1000 milliseconds.
   skip_error_files	Specifies whether to skip files that fail to back up. false (default): Does not skip files that fail to back up. true: Skips files that fail to back up.

   The following code provides a configuration example for the hbr.config file:

   retry_times=30
   retry_interval=1000
   skip_error_files=false

Uninstall the client

To the right of Client Operation, you can select ┇ > Uninstall. After the client is uninstalled, its status changes to Unmounted.

Virus scan

The Cloud Backup service provides a backup point virus scan feature to prevent files that contain viruses from being restored to the production environment. This feature helps you select clean and safe backup points for data restoration. On the Backup Details tab, find the target backup point in the Backup History area. In the Actions column, click the ... > Virus Detection to scan the files for viruses.

Backup vault replication

To maintain business continuity and protect against regional disasters or account management risks, Cloud Backup supports configuring cross-region backup or cross-account replication for backup vaults where the Vault Type is General Backup. After configuration, data from the source backup vault is automatically synchronized to the replication target vault, ensuring data consistency between the two locations. You can also perform cross-region data restoration from the replication target vault as needed.

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

In addition, ECS File Backup also supports enterprise-grade features such as cross-account backup, automatic archiving, KMS encryption, backup lock, and automatic resource association for backup based on tags.
