Configuring Remote Backup
Scenarios
To perform remote backup is to back up the data of a server to another server. Currently, it is only supported for Linux servers.
When you enable WTP on a Linux server, specify a local backup path. HSS will back up protected directories to that path. (The user-defined excluded subdirectories and file types will not be configured). Once the files in the protected directories are modified, HSS will automatically restore them.
For higher security, configure remote backup. Even if local server backup is damaged by attackers, you can log in to the remote backup server, go to the backup path, and obtain the remote backup to manually restore tampered web pages. You can view the backup path on the Manage Remote Backup Servers page. For details, see Modifying a Remote Backup Server.
Constraints
- Only Linux servers support remote backup.
- A remote backup server must be a Huawei Cloud Linux server. Ensure the server status is Running, and the server has an HSS agent in Online status.
- The remote backup server must connect to the protected server. To enjoy quick and stable backup, put the two servers in same intranet.
Remote Backup Configuration Process
Perform the following operations:
For details about how to modify or disable remote backup, see Modifying a Remote Backup Server and Disabling Remote Backup.
