Check that your Synology NAS and the HCI cluster are both network connected and can interact with one another. This can be accomplished by connecting them to the same network or by establishing a separate backup network.

Backing up virtual machines (VMs) in a hyper-converged infrastructure (HCI) to a Synology NAS for disaster recovery purposes is a common practice. Here's a general guide to help you through the process:
  • Ensure Network Connectivity: Make sure your Synology NAS and the HCI cluster have network connectivity and can communicate with each other. This can be achieved by connecting them to the same network or creating a dedicated backup network.
  • Select Backup Software: There are several software tools available that can help you back up VMs to a Synology NAS. Some popular options include Veeam Backup & Replication, Commvault, and Acronis Backup. Evaluate the features, compatibility, and ease of use of each solution to choose the one that best fits your requirements.
  • Install and Configure Backup Software: Install the chosen backup software on a dedicated backup server or a VM within your HCI cluster. Follow the software's documentation to configure it properly. You'll typically need to provide credentials and network details for connecting to your Synology NAS as the backup destination.
  • Define Backup Policies: Set up backup policies based on your requirements. Determine the frequency of backups, retention periods, and the VMs you want to include in the backup jobs. The software should provide options to configure incremental or differential backups to optimize storage usage and backup duration.
  • Perform Initial Full Backup: Run the initial full backup of your VMs to the Synology NAS. This process may take some time depending on the size of the VMs and the network speed. Ensure that the backup completes successfully.
  • Schedule Incremental Backups: Set up scheduled incremental backups according to your desired frequency. Incremental backups capture only the changes made since the last backup, reducing the backup time and storage requirements.
  • Test and Validate Backups: Periodically perform restoration tests to ensure that the backups are valid and can be restored successfully. This step is crucial for verifying the integrity and reliability of your backup solution.
  • Monitor and Maintain: Regularly monitor the backup jobs to ensure they are running as scheduled and without errors. Monitor the available storage on the Synology NAS and plan for its expansion if necessary.

Hi,

When adding an iSCSI server to Sangfor HCI, enabling hardware acceleration for external storage can help improve performance and stability by offloading storage-related tasks to a dedicated hardware component. This can help reduce the workload on the CPU and improve overall system performance.

Using a NAS (Network Attached Storage) device for iSCSI storage may or may not solve this problem, depending on the specific hardware and configuration. Some NAS devices may support hardware acceleration for iSCSI storage, while others may not. Additionally, the performance and stability of the iSCSI storage will also depend on factors such as the network bandwidth, latency, and disk I/O performance.

Thanks
