Backup H3C CAS virtual machines using Yun Yu virtual machine backup software

1. Enter the Yun Yu virtual machine backup system and select "Backup/Restore"-"virtual machine backup" to create a new backup task.

2. Under H3C CAs virtualization type tick the virtual machine that you want to back up, the selected virtual machine appears under selected virtual machine, scroll to the bottom of the page, and click Next.

3, Backup mode you can select "Backup by Policy" and "one Time backup".
If you select backup by policy, the backup is performed according to the time policy you set. Select the backup type First: Full backup, incremental backup, differential backup.
Full backup will back up all the data from the backup source, and the backup data becomes a full backup point in time and all data is backed up. An incremental backup is a backup of the source data on the basis of the last backup, depending on the previous backup point, and only the change data that was last completed to the current time is backed up. A differential backup is a backup of the source data on the basis of the last full backup, dependent on the last full backup point, and only the change data that was completed to the current time of the last full backup is backed up.
In general the case. It is recommended that you make a full backup weekly/monthly, make an incremental backup every day, and a full backup in the same task can be combined with an incremental or differential backup, but incremental and differential backups cannot be set at the same time. If only incremental or differential backups are set up, the first run task is automatically downgraded to a full backup.
You can set the run time policy under each backup type, and you can select Daily, weekly, monthly, and the user can set the value of the virtual machine business accordingly. If the scroll execution switch is turned on, the task is scrolled between the start and end times, and the user sets the scrolling interval between each end of the task and the next task's start time.

If you select a one-time backup, the task performs a full backup at the point of selection. Click the calendar icon to set the time to perform the task, which can be as precise as 5 minutes.

After selecting the Backup method, click Next.

4. Advanced Configuration of backup tasks, set backup destination, storage policy, transport policy, retention policy, backup mode.
"Backup Destination": The default is to automatically select the node, if there are multiple storage, users can also manually select the backup storage destination according to their own needs.

Storage Policy: There are two options for data deduplication and compressed storage. Turning on deduplication will reduce the size of the data store by reducing the amount of data stored in the backup data, which is recommended if you have a large number of duplicate data. When compressed storage is turned on, the backup data is compressed by the block size, which helps save storage space.

"Transport policy": Transfer encryption using AES 256 encryption algorithm, the transmission encryption will be the backup source to the backup storage transmitted data encryption, the use of ciphertext transmission, to protect the user's data security.

Retention Policy: The backup system retains the specified number of days/numbers of backup data, and the earliest backup data that exceeds the specified number of days/numbers is automatically deleted. The number of Citrix XenServer virtualization type retention policies calculates only a full backup point, excluding incremental or differential backup points that are attached to this full backup point.

"Backup Mode": There are two options for "High speed mode" and "Silent Snapshot". Turning on high-speed mode retains a snapshot at the end of the task, and the next time you run the backup task, you do not need to calculate the data block's checksum information to speed up the backup location of valid data. Silent snapshots Enable file systems and applications to be in a consistent state through application-aware programs such as XenServer tools. The Windows operating system requires the app to support VSS to ensure the data consistency of the app. If a silent snapshot fails after a silent snapshot is turned on, the pornographic silent snapshot is automatically attempted.

After setting up the Advanced configuration, click "Next".

5、确认配置信息。对任务的配置信息作确认，并可修改任务名称，滚动页面到底部，点击【提交】。

6、提交任务后自动跳转到【当前任务】页面，可以查看刚才创建的备份任务。点击右侧的“操作”按钮可以手动运行或停止任务，也可以等待系统按照设定的策略自动执行备份任务。点击任务名称，可以进入【任务详情】页面。

7、在【任务详情】页面左上方显示任务运行时数据传输的流量速度，右上方显示任务的配置信息，下面显示备份任务的运行日志、虚拟机列表和历史任务。
