Network issues are one of the most common causes of slow backup and restore operations. In this demo, learn how to check network performance in Commvault using both the Job Details throughput breakdown and the CVNetworkTestTool.

You’ll see how Commvault helps you identify potential network bottlenecks, validate connectivity between clients and media agents, test data transfer performance, and interpret throughput values to pinpoint where slowdowns occur.

This step-by-step tutorial shows how to run lookup tests, service checks, and full read/write/delete performance tests — helping you quickly determine whether network conditions are impacting data protection jobs.

What This Video Covers
Understanding how network performance impacts backup and restore throughput
Using Job Details to analyze Read, Write, DDB, and Network throughput categories
Identifying possible network bottlenecks based on performance breakdown
Locating and launching the CVNetworkTestTool
Running lookup tests to verify DNS and host resolution
Performing service and port checks on clients, Media Agents, and CommServe
Running network tests in client–server mode for throughput validation
Adjusting test settings such as buffer size for slow network links
Interpreting read, write, and delete throughput test results
Running multiple tests and comparing results to establish baselines

TL;DR
Use Commvault's Job Details throughput metrics and the CVNetworkTestTool to test network connectivity, validate throughput, and detect bottlenecks impacting backup and restore performance.

Key Takeaways (Rewritten for Network Focus)
Identify slow jobs using Job Details throughput categories: Read, Write, DDB, Network
Analyze whether high Network throughput percentage = network bottleneck
Use CVNetworkTestTool.exe to test network performance between clients and media agents
Run DNS checks, service checks, and port validation for connectivity
Execute read, write, and delete throughput tests in client/server mode
Use customizable test settings for slow or limited network links
Run multiple tests and average results for reliable performance baselines
Quickly determine whether lag is environmental (network) or workload-related

FAQ
Q: How does Commvault detect network-related slowdowns?
A: Job Details shows throughput by category; high Network usage often indicates a network bottleneck.

Q: What is CVNetworkTestTool used for?
A: It tests connectivity, validates service ports, and measures network throughput between two Commvault machines.

Q: What tests can I run?
A: Lookup tests, service checks, and data throughput tests (read/write/delete).

Q: Why does the tool run in client/server mode?
A: It simulates the real data path between a client and media agent, providing accurate network performance metrics.

Q: How should I interpret test results?
A: Run several tests, average throughput, and compare against expected baseline performance.
