Backup Management
Overview
The backup management module provides a set of functions for data protection and disaster recovery.
This section introduces the main features of backup management, as well as step-by-step guidance for data protection and disaster recovery.
Feature Overview
ZStack ZSphere provides a centralized UI interface for managing protected resources, backup data, backup plans, and backup storage.
The backup service in ZStack ZSphere is based on periodic scheduled backups. Through backup policies, data retention policies, and backup QoS, you can customize and create backup plans that meet your business needs, and then apply these backup plans to virtual machines or platform databases that require backup protection.
ZStack ZSphere offers multiple backup policies for different backup objects, easily meeting virtualization backup requirements. For virtual machines, we provide default incremental backup and customized incremental backup policies. For the platform database, you can customize the backup cycle, execution time, and start time.
ZStack ZSphere supports local and remote data protection, making data more reliable. Local backup storage supports seamless failover, effectively ensuring business continuity. Additionally, backup data can be synchronized from local backup storage to remote backup storage.
ZStack ZSphere provides detailed information about backup-related activities. With just a few clicks, you can easily monitor the status of backup plan executions and the capacity usage of backup data.
Preparation
- Make sure the installed software version is ZStack ZSphere 4.3.0 or above.
- By default, ZStack ZSphere provides a free trial quota for
backing up 6 virtual machines. You do not need to purchase additional licenses
to try out the backup feature.
Once the number of protected virtual machines reaches the free trial quota limit, if you wish to continue using the backup feature, purchase a Plus license. ZStack ZSphere offers backup licenses in two ways: by the number of virtual machines and unlimited authorization. After secondary authorization, the authorized quota will override the free trial quota, for example: if the original free trial quota is 6 and the purchased authorized quota is 50, then the final effective authorized quota will be 50.
Add a Backup Storage
To use the backup feature, you need to deploy a backup storage in ZStack ZSphere to store backup data. Depending on your backup scenario, you can add local backup storage or remote backup storage.
Add a Local Backup Storage
Add a local backup storage to store scheduled backup data for local virtual machines or the platform database. Local backup storage supports seamless failover to effectively ensure business continuity.
In case of accidental deletion or data corruption locally, you can restore backup data from local backup storage back to your local environment.
In the event of a disaster at the local data center, you can completely rely on the local backup storage to rebuild the data center and recover businesses.
- Reuse an existing image storage to store backup data. For more information, see Ruse Image Storage.
- Reuse an existing host and utilize free capacity on the host to store backup data. For more information, see Ruse Host.

Virtual Machine Backup
In ZStack ZSphere, the backup service is based on periodic scheduled backups. To perform a backup, you need to configure a backup plan. For more information, see New Backup Plan.
During executions of backup plans, the backup mode, backup chain length, backup data retention policy, and backup QoS all depend on the configured backup policy. For more information, see Backup Policy.
After you performed backups, you can use them to restore virtual machines. For more information, see Data Recovery.
Backup Policy
Backup Policy
- Default Incremental Backup
You only need to customize the incremental backup policy, while the full backup policy is set by default. After 63 incremental backups, the system automatically performs a full backup, with a maximum backup chain length of 64.
- Customized Incremental Backup
You need to customize both the incremental and full backup policies. By customizing the full backup policy, you can shorten the interval between full backups. Increasing the number of full backups shortens the backup chain and reduces the amount of backup data that needs to be merged during recovery.
- For the incremental backup policy, ZStack ZSphere provides multiple options including monthly, weekly, daily, hourly, and minute-based backups.
- For the full backup policy, ZStack ZSphere supports monthly and weekly backups.
- Backup by Month: If you set the execution time to 00:00 on the first day of each month, the incremental backup is executed at 00:00:00 on the first day of each month.
- Backup by Week: If you set the execution time to 00:00 on Sunday and Tuesday of each week, the incremental backup is executed at 00:00:00 on Sunday and Tuesday of each week.
- Backup by Day: If you set the execution time to 00:30, the incremental backup is executed at 00:30:00 every day.
The backup plan begins at the start time and executes backups according to the configured backup cycle and execution time.
Retention Policy
- Local Retention Policy:
- Retain by quantity: Retain a minimum of 1 local incremental backup data and 1 local full backup data.
- Retain by time: Retain a minimum of 1 day of local backup data.
- Remote Retention Policy:
- Retain permanently: Remote backup data will not be automatically cleaned up.
- Retain by quantity: Retain a minimum of 1 remote incremental backup data and 1 remote full backup data.
- Retain by time: Retain a minimum of 1 day of remote backup data.
Note: For data generated beyond the retention policy, only the backup records
are deleted, which does not affect the data security.New Backup Plan
