Back up ECS files

Create a backup plan

1. On the ECS File Backup Standard Edition page, select the region of the target ECS instance, and then click Add ECS File Backup Standard Edition.

   Note

   If you are using the old console (which displays Try New Version in the upper-right corner), go to the ECS Instances tab and click Actions in the Back Up column of the target instance.

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

   Parameter	Description
   Account	Specify the account to which the backup resources belong. By default, the current account is selected. You can also select an added account whose resources you want to back up. Only one account can be selected. To manage cross-account backups, click Manage cross-account backups. Note If you are using the old console, select the account on the ECS instance list tab.
   ECS to Back Up	Select the ECS instances that you want to back up. You can select multiple instances to create backup plans in bulk. Note If you are using the old console, this parameter is automatically configured based on the selected ECS instance.
   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 Exclude System Folders is enabled, the system directories excluded on Windows and Linux are not included in the backup plan. To view details about the excluded system directories, click Exclude System Folders and then click the icon to the right. If Exclude System Folders is not enabled, all directories are included in the backup plan. If you select Specified Folders, specify the Source Paths. Click Add Folder to add multiple backup directories. The backup path rules are as follows: You can enter up to eight paths if you do not use a wildcard character (*). You can enter only one path if you use a wildcard character (*). Wildcards such as /*/* are supported. Each line must specify an absolute path that starts with /, \\, C:\, or D:\. When VSS is enabled, multiple paths, UNC paths, wildcards, and file exclusions are not supported. When UNC paths are used, VSS, wildcards, and file exclusions are not supported. If the backup source includes 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, and file name extensions are ignored. If you select Specified Type, specify the file types to back up in the Select File Type box.
   Backup Policy	Select an appropriate backup policy from the drop-down list. Cloud Backup automatically backs up data sources based on the backup policy that you configure. A backup policy mainly covers the backup vault encryption method, backup interval, backup retention period, geo-redundancy replication policy, automatic backup archiving, and backup point virus detection, helping you flexibly manage the assets of each data source. If the default backup policies cannot meet your backup plan, click Create Backup Policy or Edit Policy to manage backup policies. For more information about the parameters in a backup policy, see Policy Center.
   Use VSS	Specifies whether to use the Windows Volume Shadow Copy Service (VSS) feature to accelerate backups. This feature is available only for Windows. Note When you use VSS, you cannot back up multiple paths or UNC paths, use wildcards, or exclude files. To use VSS, turn on the Use VSS switch.
   Enable Bandwidth Throttling	Bandwidth throttling helps you control backup traffic during peak business hours to avoid affecting your services. To use bandwidth throttling, turn on the Enable Bandwidth Throttling switch, select a Time Range (Hour) based on your business requirements, enter the maximum Max Bandwidth (MByte/s) that backups can use within the throttling period, and then click Add.

3. Click OK to complete the configuration.

Backup run status

View backup jobs

At the scheduled backup time, Cloud Backup starts the backup job.

On the Backup Jobs tab, a Status of Completed indicates that the backup was successful. You can view details for the backup job, such as Total Scanned Data Amount at Source, Completed Backup Data Amount, Data Amount Written to Backup Vault, and Backup Speed. See the tooltips in the Cloud Backup console for descriptions of these metrics.

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

Browse backup files

The Browse feature allows you to browse backed-up files. If virus detection has been performed on the backup point that you want to browse, files infected with viruses are marked.

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

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

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

Extend backup point retention

To retain a backup for a longer period, extend its backup point retention period.

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

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

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

   After the setting is complete, you can view the new expiration time in Expires At.

Delete backups

Delete the backup point data that is generated by the backup client.

In list mode in Backup History, delete backup points by using either of the following methods.

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

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

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

Run a backup immediately

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

Modify a backup plan

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

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

3. Click OK.

Pause or resume a 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. You can 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 confirm the pause.

  After a plan is paused, subsequent backup jobs will not run. Existing backup points are not affected and expire based on their retention period. If the "keep at least one backup version" setting is enabled, the last backup version is not subject to the retention period. If backup points still exist for the ECS instance after the plan is paused, billing for the ECS instance continues.

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

Delete a backup plan

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

Reinstall the backup client

To reinstall the client, select ┇ > Reinstall under Client Operation. After the installation is complete, the client status changes to Activated.

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

Configure client parameters

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

Configure retry parameters

If a file backup fails, for example, due to an unstable network, you can configure the following parameters to enable automatic retries.

1. Log on to the server whose files you want to back 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 must be in the same directory as the hbrclient and ids executable programs.

4. In the hbr.config file, add the following parameters.

   Parameter	Description
   retry_times	For clients of version 2.16.0 and later, this parameter specifies the number of data backup retries. The default value is 30.
   retry_interval	For clients of version 2.16.0 and later, this parameter specifies the data backup retry interval. The default value is 1,000 milliseconds.
   skip_error_files	Specifies whether to skip files that fail to be backed up. false (default): Does not skip files that fail to be backed up. true: Skips files that fail to be backed up.

   The following code provides a sample configuration of the hbr.config file:

   retry_times=30
   retry_interval=1000
   skip_error_files=false

Uninstall the client

To uninstall the client, select ┇ > Uninstall under Client Operation. After the client is uninstalled, the client status changes to Unmounted.

Virus detection

To prevent infected files from being restored to your production environment, Cloud Backup provides the Backup point virus detection feature. This helps you select an uninfected backup point for future restores. On the Backup Details tab, in the Backup History section, find the backup point you want to scan, click ┇ in the Actions column, and then select Virus Detection.

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 where the Storage Vault Type is General Backup. Once configured, data from the source backup vault is automatically synchronized to the destination backup vault, ensuring data consistency between the two locations. You can also perform cross-region data recovery from the destination backup vault as needed.

For general-purpose backup vaults that store ECS files, backup vault replication provides an effective solution for cross-region or cross-account disaster recovery.

In addition, the standard edition of ECS file backup supports other enterprise-grade features, such as cross-account backup, automatic archiving, KMS-based encryption, immutable backup, and tag-based automatic resource association and backup.
