Backup VM Method in Sangfor HCI Supports Backup of VM Layer or Together with OS layer?

Hi everyone, just have a question regarding the backup method outcome or process. I'm quite new in the virtualize technology n stuff so I hope u guys can share your thoughts.

Recently there's a project using Sangfor hDR where a backup/restore method is used to restore the VM in DR site. The user had asked me that does the restore method or backup method include in the OS layer. So, I've never thought about it before cuz I thought when backup method included everything in a VM when is done.

So my question is that does it include everything in a VM such as VM layer or OS layer etc when a backup is done on it or the backup does not cover certain data of a Vm in HCI environment? I would also like to know the comparison of other brands for their backup method or even features that may differs with Sangfor if you guys know anything about it.

Sangfor HCI supports the backup of both the VM layer and the OS layer. When a backup is performed, it includes everything in a VM such as the VM layer, OS layer, and other data1. This means that the backup method in Sangfor HCI is comprehensive and ensures that all aspects of a VM are backed up.

To create a Sangfor HCI backup job, you can start from the VM Backup > Virtual Machines page by selecting target VM(s) and then click on “Create new job”, or you can get started from VM Backup > Backup page. By default, all virtual disks of the selected VMs will be all backed up.

However, if you wish to exclude certain virtual disks of certain VMs from backing up, you can do so by clicking on the VM, all the virtual disks of the VM will be shown. By either selecting the virtual disk or not, you can choose to include or exclude the virtual disk from backing up.

Good luck!

When performing a backup of a VM in a Sangfor hDR environment, the backup typically includes both the VM layer and the OS layer. This means that data within the virtual machine, including the operating system, applications, and user data, are captured in the backup. However, it's essential to configure the backup solution correctly to ensure comprehensive coverage of all necessary components. When comparing backup methods across different brands in the HCI environment, factors such as backup speed, deduplication capabilities, integration with hypervisors, support for different storage types, and ease of management can vary.

When dealing with virtual machine (VM) backups in a hyper-converged infrastructure (HCI) environment like Sangfor hDR, the backup typically includes everything within the VM. This generally encompasses:

VM Layer: This includes the VM's configuration files, virtual hardware settings, and any snapshots that have been taken.
OS Layer: The operating system installed on the VM, along with all system files, applications, and data present on the virtual disk.
In a typical backup process using Sangfor hDR or similar solutions, the goal is to capture a full image of the VM, which allows for a complete restore, including the VM layer and the OS layer. However, there are a few considerations to keep in mind:

Full VM Backups
Full Backups: These backups include the entire VM, capturing the complete state at a given point in time. This ensures that everything, from the OS to the applications and data, is included.
Incremental and Differential Backups
Incremental Backups: These capture only the changes made since the last backup (whether full or incremental). This method is more storage-efficient and faster but requires the last full backup and all subsequent incremental backups for a full restore.
Differential Backups: These capture all changes made since the last full backup. This method is also storage-efficient and faster but requires the last full backup and the last differential backup for a full restore.
Backup Strategies and Considerations
Application-Aware Backups: For applications like databases or email servers, it's crucial to use application-aware backups that ensure data consistency.
Snapshot-Based Backups: Some solutions use snapshots to capture the state of the VM, which can be quicker and less resource-intensive.
Comparison with Other Brands
Different backup solutions offer various features and methodologies. Here’s a brief comparison with some popular alternatives:

1. Veeam Backup & Replication:

- Provides agentless VM backups.
- Supports application-aware processing.
- Offers advanced features like SureBackup for automated backup verification.

2. Veritas NetBackup:

- Supports both physical and virtual environments.
- Provides deduplication, replication, and cloud integration.
- Offers extensive scalability and advanced recovery options.

HiHi,

Please find my answer below:

Q1. In Sangfor HCI environment, when a backup is performed, it includes everything within the virtual machine (VM), such as the VM layer, the operating system (OS) layer, system files, applications, and user data. This ensures comprehensive data protection for all components of the VM.

Q2. Sangfor HCI backup offers several advantages over other brands:

• Efficient backup method: Block-level incremental backup reduces backup time and storage space.
• Data deduplication: Eliminates redundant data, reducing storage requirements.
• Flexible scheduling: Daily, weekly, or monthly backups with incremental backups at specified intervals.
• Granular recovery: Restore individual files or folders without restoring the entire VM.
• Seamless integration: Designed for Sangfor HCI infrastructure, ensuring compatibility and optimized performance.
• Robust security: Data encryption, role-based access control, and auditing for data protection.
  
  

Hi,

Generally, a VM backup should capture most of the VM data including the config files, OS files and settings, and application data residing on the VM disks. But there might be some exceptions to this like the below:

    - Temporary Files and OS Caches are most of the time excluded to reduce backup size and improve performance and are typically recreated automatically when the VM restarts.
    - Data in Transit that is actively being written to the VM's disks at the time of backup might not be fully captured but this is a minor concern.
    - Application-Specific Data might manage their own data outside the standard VM disk structure

Below is a breakdown of what usuallyvgets included in a VM backup:

    - VM Configuration Files which define the VM's settings like memory allocation, virtual CPUs, and attached disks.
    Operating System Files: All system files and applications installed on the OS are captured.
    - VM Disks where the entire contents of the VM's virtual disks are backed up, including data partitions and user files.

Generally, the comparison of Backup Methods and Features whether it is Sangfor or competition s thru  the following methods:

    - Agent-based Backup or an agent software installed within the VM coordinates the backup process.
    - Agentless Backup or a backup solution which everages the hypervisor's capabilities to capture VM data without requiring an agent on the VM itself.

When performing backups of virtual machines (VMs), especially in hyper-converged infrastructure (HCI) environments like Sangfor hDR, it's crucial to understand what is included in the backup. Typically, a VM backup encompasses the entire VM, which includes all layers such as the VM layer (virtual disks, configuration files) and the OS layer (operating system, system files, installed applications, user data). This comprehensive approach ensures that the VM can be fully restored to its previous state in case of data loss or disaster recovery scenarios. However, the specifics of what is backed up can vary between backup solutions and vendors. Some backup solutions may offer granular options where administrators can choose to back up only certain data within the VM, such as specific files or applications, rather than the entire VM. Comparing backup features among different brands, like Sangfor hDR and others in the market, involves evaluating aspects such as backup speed, deduplication capabilities, recovery time objectives (RTOs), integration with virtualization platforms, support for different storage environments (e.g., hybrid cloud), and management simplicity. Understanding these differences can help organizations choose a backup solution that best aligns with their operational needs and data protection strategies in HCI environments.

Hi,
When it comes to VM backups, they generally include the entire VM, which means all the data and configurations of the VM, including the OS layer, applications, and files

In a virtualized environment like with Sangfor hDR, the backup typically includes the entire VM, covering the OS layer, applications, and data. It captures a snapshot of the VM, so during restoration, it should restore the entire state as it was at the time of the backup. Other brands, such as VMware, Veeam, and Nutanix, offer similar comprehensive backup solutions. However, the features and performance might vary, with differences in ease of use, integration capabilities, backup speed, and restoration processes.

Hi,

Sangfor HCI 6.9.0 supports VSS backup for both Windows virtual machines (support for Linux VMs is on the way)
