Key Performance Factors
The speed and efficiency of backup scans depend on several variables:
Infrastructure Components
- Backup Repository Storage Type: Performance varies significantly between HDD and NVMe SSD storage.
- Network Capacity and Repository Performance: Ensure sufficient network bandwidth and repository throughput.
Workload Characteristics
- Total Allocated Storage Size and File Count: Larger datasets and higher file counts may impact scan duration.
- Type of Files: Certain file types may affect scan performance.
- Number of Virtual Machines (VMs): More VMs typically require additional workers.
-
Scan Type and Configuration: The chosen scan type and plan setup can influence performance.
- Ransomware detection scans
- Malware scans ( full and incremental )
Worker Requirements
To optimize performance, use the following guidelines to estimate the number of scan workers required:
- Traditional HDD Storage: 1 scan worker per 1.5TB of data.
- NVMe SSD Storage: 1 scan worker per 10TB of data.
Scan Worker Hardware Requirements:
- Compute: 4 vCPUs and 16GB RAM.
- Storage: Minimum of 250GB - 350GB for Commvault environments.
- Storage: Minimum of 60GB for Veeam environments.
Best Practices
- Right-Sizing Backup Infrastructure: Ensure your backup infrastructure is appropriately sized for your workload.
- Avoid Resource Throttling: Ensure network and disk resources are not constrained.
- Monitor Cluster Metrics: Regularly monitor Elastio cluster metrics to verify adequate worker count and scan performance.
