Checking into why my backups (for some VMs) I saw this errors

---------------------------

It takes sometimes 2 hours to do the backup just because it sits there waiting for over 1 hour. Even that the 2 drives are 100G, one is used to like 20% the other about 1%, it is not the size of the drives.

I read in another post about the agent been installed, I do have the agent installed on the VMs and selected as 'yes' on the GUI.

Any solution to this?

Hi,

is the agent running?
Did you shut down the VM after you add the Guest option?

Yes and yes, several times.
These are other errors from today's backups. (Backups still run, and they are good, I tested several )
One completely failed

This last one is the worst offender, it stays TRYING for 35thousand times (about one hour) .. I am killing this VM today or tomorrow..

But yes, I do follow the same procedure on all the VMs with the agent even that in some case it "works' and other dont, like in memory reporting for instance, in some cases it reports as using all the ram given to the vm, even when you go into the vm, and the usage is very low.
