Troubleshooting High Backup Repository Usage in Sangfor HCI

Hello Sangfor Community,
I am George Fady, Technical Support Engineer, and I would like to share a practical troubleshooting case related to high backup repository usage in Sangfor HCI.
Problem Description
An alert was triggered indicating that the backup repository of the following datastore had reached a high usage threshold:
Datastore: VirtualDatastore1
Backup Repository Usage: 92.35%
The alert indicated that the backup repository was approaching its capacity limit and required attention to prevent backup operations from being affected.
Root Cause
The backup repository had limited remaining free capacity.
The repository capacity and usage were:
  • Free Capacity: 7 TB
  • Used Capacity: 6.46 TB
  • Usage: 92.35%

The high usage level triggered the HCI storage alert.
Resolution Steps
To resolve the issue and increase the available backup repository capacity:
  • Navigate to:

Reliability → Scheduled Backup/CDP → Backup Repositories
  • Locate the affected Backup Repository.
  • Adjust the Backup Repository Capacity according to the available storage resources and backup requirements.
  • Monitor the repository usage after increasing the capacity to ensure that sufficient free space is available.

Key Takeaway
High backup repository utilization should be addressed before the repository reaches full capacity, as insufficient storage space can affect backup operations and overall data protection.
When troubleshooting backup repository alerts, it is important to check:
Repository Capacity → Used Capacity → Free Capacity → Backup Retention → Repository Configuration
Regular monitoring of backup repository usage can help prevent unexpected backup failures and ensure that sufficient storage is available for scheduled backup and CDP operations.
I hope this troubleshooting case helps other engineers working with Sangfor HCI.
Feel free to share your experience with backup repository capacity management and storage-related alerts in the comments.
