Step1: Configurate backup repository. Before creating backup policy, you need to set the backup repository first. Go to Disaster Recovery > Scheduled Backup > Scheduled Backup Policy > Backup Repositories. Click Add (if the SCP manage server HCI cluster you can select the specify cluster in the Available section). Select the storage as the backup repository, Click OK (if available space is not enough available space you can add a new one in storage). In the right side select the purpose and capacity of the current datastore select backup (you can select all at the same time).

The Purpose of the storage includes the following type:

1. Backup: Platform administrators and tenants can use this datastore for backups.
2. Disaster recovery: Platform administrators and tenants can use this datastore for disaster recovery.
3. Back copy: Only platform administrator can use the datastore for backup copy tasks.
4. Backup archive: Platform administrators and tenants can use this datastore for backup archives.

After adding the datastore added successfully. You can change the capacity and purpose by clicking the Edit button. By clicking Backups, you can view the backups the VM already backup to this datastore. And you can also remove the datastore by clicking Remove.

When the virtual machine's storage location and its backup storage are the same, the platform will prioritize the data storage needs of the virtual machine. For example, when storage space is insufficient, if the backup space is set to 100GB, the available space for virtual machine backups may be less than 100GB because it will be prioritized for use by the virtual machine.

Step2: go to Disaster Recovery > Scheduled Backup > Scheduled Backup Policy click New.

Step3: Select the Virtual Machine that needs to be added to the backup policy.

Applicable Scope: If the virtual machine belongs to a tenant, select Tenant; if the virtual machine belongs to an administrator, select Sangfor Cloud Platform.

Auto add VMs in specified groups: Selecting this option will automatically add new virtual machines created in a specific virtual machine group to the backup policy.

Step 4: Configure backup schedule.

Incremental Backup: For incremental backup you can select Weekly, Daily or Hourly. When you select Weekly or Daily there is a backup timeout and Max Duration option. By configuring the max duration When the time is reached, the ongoing backup task will not be canceled, while subsequent backup tasks will not be executed until next backup starts, but when you checked the backup timeout option at the same time, SCP will cancel ongoing backup task upon timeout

Quiesce Guest File System:

1. You can enable this option to quiesce the guest file system before backup, so as to ensure the data backed up is consistent with the file system data.

2. It is not recommended to enable this option when I/O is busy or backups are frequently created.

3. The guest file system may fail to be quiesced due to high disk IO. It is recommended to enable this feature when the disk IO usage is low.

The following is the OS supported by quiesce guest file system function.

Full Backup: Check this option the VM will perform regular full backups, you can select monthly or weekly perform the full backup. The features of full backup are as follows:

1. Reduces the number of VM backups and improves IO performance of the recovered VM in data fetching phase.

2. Full backup is periodically executed and is not influenced by incremental backups. The backup task will not be canceled due to timeout.

3. Priority of full backup is higher than that of incremental backup, which will not be executed when full backup task is in progress.

4. Full backup consumes more resources and may take more time to complete.

Backup Health Check: Check the availability of backup files, time can select monthly or weekly.

Backup Retention: Click Backup Retention Settings go to the setting page. The unit for the period can be selected as days, weeks, months, or years.

Step 3: Select backup repository configured in step1.

Archive backups to another repository: Merge backups and archive them to the specified repository. By clicking the Advanced button, you can define the start month, start data, file retention period and compress archives. When checked Compress archives can save storage space but may consume more CPU resources and increase time spent on archiving backups and fetching data after recovery.

Step 4: configurate the policy name. in this step you can fill in the policy name and the description.

Step 5: Configuration confirmation. Confirm the backup policy information, click OK.
