Hi,

Is there any statistic, maybe in logs, what amount of data is send from storage to media agent during restore? In backup we have “Data transferred on network” but what about restore?

I mean - let’s say I’m restoring something from Disk Library or Azure - data in library is deduplicated and compressed. I know that dedupliaction doesn’t matter here, but what about comporession? I believe media agent get compressed data from storage, uncompress it and then send to the client? So size of application will be not the same as the data size taken from storage? How to check it?

 

Regards

    Hi, 

    It was rather a general question, but for me the most important are virtual agent, SQL Server and File System.

    Hi,

    • You can estimate the amount of data sent from storage to the MediaAgent during restore by analyzing the cvfwd.log for throughput and transfer statistics.
    • The actual amount of data read from storage (compressed) will be less than the application size (uncompressed) sent to the client if compression is enabled.
    • There is no direct "Data transferred on network" metric for restore jobs in the UI, but log analysis provides insight.
