Enabling Backup
Scenarios
So far, no tools can defend against all ransomware. You can enable backup for servers, so that their data can be restored in a timely manner in the case of a ransomware attack.
Ransomware backup can be performed in two modes: scheduled backup and immediate backup upon ransomware detection. You can create a custom scheduled backup policy to periodically back up servers. If HSS detects a suspected ransomware attack, it will immediately trigger a backup to ensure service data is stored as much as possible.
This section describes how to enable ransomware backup.
(Optional) Step 1: Purchasing a Backup Vault
You can purchase a backup vault on the HSS console by referring to this section, or on the CBR console.
- Log in to the management console.
- Click
in the upper left corner and select a region or project.
- In the upper left corner of the page, click
and choose .
- Choose Server Protection > Ransomware Prevention.
- Toggle on ransomware backup. In the dialog box that is displayed, click Next.
- In the displayed dialog box, set the vault parameters.

Ransomware backup can only be used to restore data after a ransomware attack to reduce some losses. To detect and defend against ransomware attacks in real time, enable ransomware prevention. For details, see Enabling Ransomware Prevention.
