In steady state, what is the approximate rate of data removed from an Avamar grid during a daily garbage collection?

In a stable, operational Avamar grid (steady state), the generally accepted approximate rate for garbage collection is 10 GB of dereferenced data removed per hour, per data node. This is a rule-of-thumb performance metric used for capacity planning and operational monitoring. The actual rate can fluctuate based on the specific Avamar hardware generation (e.g., Gen4S, IDPA), data churn, and overall system load, but 10 GB/hr/node serves as a reliable baseline for a typical environment.

B. 10 GB per hour for an entire grid is significantly too low, as the total cleanup rate is the sum of all nodes' efforts.

C. 100 GB per hour per node is an exceptionally high rate and not representative of typical, sustained garbage collection performance.

D. This rate is too low for a multi-node grid and is less precise than a per-node metric, which is the standard way to measure this process.

Dell EMC Avamar Technical Note "Avamar Garbage Collection" (P/N 300-012-789 Rev A04), Page 10, Section "Performance": "In a steady state, garbage collection can remove about 10-15 GB of data per hour per node." (Note: While this is from an older document, the figure remains a widely used baseline for exam purposes on established systems).

2. Dell Avamar Administration Guide, "Garbage collection overview" section describes the process. While modern guides avoid specific performance numbers due to hardware variance, this established metric is foundational knowledge for the platform.
