Abstract: Methods and system for securely capturing workloads at a live network for replaying at a test network. The disclosed system captures file system states and workloads of a live server at the live network. In one embodiment the captured data is anonymized to protect confidentiality of the data. A file system of a test server at the test network is mirrored from a captured state of the live server. An anonymized version of the captured workloads is replayed as a request to the test server. A lost or incomplete command is recreated from the states of the live server. An order of the commands during replay can be based on an order in the captured workload, or based on a causal relationship. Performance characteristics of the live network are determined based on the response to the replayed command.
