Performance

[lonblu]

How reliable is the speed counter in the Agent?
Have you ever seen such speed? This is a vm in a nvme disk copying to an optane enabled hdd.
HOw to reproduce this performances? All other backups go are below 400 mB/s in average.

Hi lonblu.

It looks like incremental backup. Can you elaborate if CBT driver was installed on this machine? Thank you.

I actually think this might be a bug as I saw this in some environments as well, even during full backups. I haven't dug into the logs, but it seems like we only poll for information about the agent progress every so often. It seems like, if the agent managed to backup an entire drive between polling periods, that we see that we don't properly calculate how long it actually took to transfer all of the data. Here's a screenshot of a full backup of one of my SQL clusters, notice that both the E and F drives show a crazy speed and that they backed up in zero seconds:
