Managing Remote Backup Servers

Constraints

Servers that are protected by the HSS WTP edition can perform application WTP-related operations.

Prerequisites

The following servers can be used as remote backup servers:

Huawei Cloud Linux servers whose Server Status is Running and Agent Status is Online

• The remote backup function can be used when the Linux backup server is connected to your cloud server. To ensure a proper backup, you are advised to select a backup server on the same intranet as your cloud server.
• You are advised to use intranet servers least exposed to attacks as the remote backup servers.

   Table 1 Backup server parameters

   Parameter	Description
   Address	This address is the private network address of the Huawei Cloud server.
   Port	Ensure that the port is not blocked by any security group or firewall or occupied.
   Backup Path	Path of remote backup files. If the protected directories of multiple servers are backed up to the same remote backup server, the data will be stored in separate folders named after agent IDs. Assume the protected directories of the two servers are/hss01 and hss02, and the agent IDs of the two servers are f1fdbabc-6cdc-43af-acab-e4e6f086625f and f2ddbabc-6cdc-43af-abcd-e4e6f086626f, and the remote backup path is /hss01. The corresponding backup paths are /hss01/f1fdbabc-6cdc-43af-acab-e4e6f086625f and /hss01/f2ddbabc-6cdc-43af-abcd-e4e6f086626f. If WTP is enabled for the remote backup server, do not set the remote backup path to any directories protected by WTP. Otherwise, remote backup will fail.
