Tag feature for ECS File Backup-Cloud Backup(Cloud Backup)-阿里云帮助中心

You can use tags to mark Cloud Backup clients. This lets you group clients that serve the same purpose, which simplifies searching and resource aggregation. This topic describes how to set tags for ECS File Backup and Local File Backup clients.

Preparations

You have granted the required permissions and installed the ECS File Backup client. For more information, see Prerequisites.

Background information

You can set tags for backup clients to classify and manage them. These tags are associated with the Cloud Backup client and are separate from the tags of the ECS instance. For example, you can set a tag such as project:a to group clients by project or department. This helps you quickly find and manage specific clients during maintenance.

Usage notes

A tag is a key-value pair.
Each tag key must be unique for a resource.

If you add a tag with a key that already exists for the resource, the new value overwrites the old value. For example, if a client has the tag company:a and you add the tag company:b, the original tag is replaced by company:b.
Tags are region-specific. For example, a tag created in the China (Hangzhou) region is not visible in the China (Shanghai) region.

Precautions

Note the following limits for tags:

Limits	Limit
Maximum key length	128 characters
Maximum value length	128 characters
Maximum number of custom tags for a single resource	20
Key Value	Cannot start with `aliyun` or `acs:`. Cannot contain `http://` or `https://`. Cannot be an empty string.
Value constraints	Cannot contain `http://` or `https://`.

Set tags

You can set tags for ECS File Backup and Local File Backup clients on the details page of the protected resource. For Local File Backup, you can also set tags for a client on the Local File Data Source tab.

In the navigation pane on the left, choose Back Up > ECS File Backup.
In the upper-left corner of the top menu bar, select a region.
Click the name of the target ECS instance to go to the details page of the protected resource. In the title of the Client Information area, click the icon.
In the Client Tags dialog box that appears, click Edit.
In the Key and Value text boxes, enter a key-value pair and click Save.

To set multiple tags, click Add a Row to add a new tag.

Search for resources by tag

On the ECS File Backup page, click Return to Old Version to switch to the classic console. On the ECS Instance List tab, set the search condition to Client Tag, enter the tag information, and click Search.
