Local Backup Server

On the main menu of ZStack Cloud, choose Platform O&M > Backup Management > Backup Server > Local Backup Server. On the Local Backup Server page, click Add Local Backup Server. Then, the Add Local Backup Server page is displayed.

You can add a local backup server by using one of the following methods:

Use an existing backup storage as the local backup server.
Add a new server as the local backup server.

Use an Existing Backup Storage as the Local Backup Server

On the displayed page, set the following parameters:

Addition Method: Select Existing Backup Storage.
Note: After you add the backup storage, you can modify the name and set the data network for the backup server on the details page.
Backup Network: Optional. Set the backup network. If you deployed a network dedicated to local backup, enter the network CIDR.
Note:
- If you deployed a network dedicated to local backup, you can add the network to the Cloud directly.
- In local backup scenarios, local VM instances, volumes, or databases are backed up to local backup servers by using the backup network. Local backup data is restored to the local environment by using the management network.
- Using a dedicated network can avoid network congestions and improve the transmission efficiency.
- If you do not specify a backup network, the management network is used by default.
Backup Data: Optional. Choose whether to scan the backup data (of VM instances, volumes, and databases) that is not deleted.
Note: Deleted backup data cannot be restored by this operation.

Add a New Server as the Local Backup Server

On the displayed page, set the following parameters:

Addition Method: Select Add Server.
Name: Enter a name for the local backup server.
The name must be 1 to 128 characters in length and can contain Chinese characters, letters, digits, hyphens (-), underscores (_), periods (.), parenthesis (), colons (:), and plus signs (+).
Description: Optional. Enter a description for the local backup server.
Backup Server IP: Enter the IP address of the local backup server.
Note: You need to prepare a new storage server in the local data center as a local backup server.
Mount Path: Enter the path to which the storage is mounted, for example, /mnt/xxx_ds.
SSH Port: Enter the SSH port. Default: 22.
User Name: Enter the user name. Default: root.
Password: Enter the password.
Backup Network: Optional. Set the backup network. If you deployed a network dedicated to local backup, enter the network CIDR.
Note:
- If you deployed a network dedicated to local backup, you can add the network to the Cloud directly.
- In local backup scenarios, local VM instances, volumes, or databases are backed up to local backup servers by using the backup network. Local backup data is restored to the local environment by using the management network.
- Using a dedicated network can avoid network congestions and improve the transmission efficiency.
- If you do not specify a backup network, the management network is used by default.
Backup Data: Choose whether to scan the existing backup data.

Manage a Local Backup Server

On the main menu of ZStack Cloud, choose Platform O&M > Backup Management > Backup Server > Local Backup Server. Then, the Local Backup Server page is displayed.

The following table lists the actions that you can perform on a local backup server.

Action	Description
Enable Local Backup Server	Enable a local backup server when it is disabled.
Disable Local Backup Server	Disable a local backup server when it is enabled. Note: If you specify only one local backup server for a backup job, disabling the local backup server will make the backup job fail. If you specify more than one local backup server for a backup job, when you disable the active one, the backup job will be implemented on the standby one.
Reconnect Local Backup Server	Reconnecting a local backup server will update the records of the backup data on the local backup server.
Scan Backup Data	Scan the VM, volume, and database backup data that is not deleted. Note: Deleted backup data cannot be restored by the scan action.
Cleanup Data	Clean up the invalid backup data and expired temporary data that have been completely deleted from the local backup server to free up the storage space. Note: For example, after you completely deleted the local backup data of a VM instance or volume and the VM instance or volume restored from the backup data, you can release the storage space of the local backup server by performing the cleanup operation.
Update Password	Change the password of a local backup server.
Delete Local Backup Server	Delete a local backup server. Note: Deleting a local backup server will stop the backup jobs and CDP tasks on the server. Please exercise caution.
