Time Machine driving me nuts

[goto]

Hi guys,

I use late 2012 low end iMac with 16GB of ram. I've it connected to TC (previous generation) via wifi. Is there a way to check what is being archived to TC? I'm working on external storage that is not archived and still more than 10GB is copied to TC several times a day. During every archiving all my ram is used by TC. I need to verify and eliminate files / folders that shouldn't be archived, because right now performance during archiving is driving me nuts...

Thank you in advance!

Did you use virtual machine app like Parallel Desktop?

I do, but virtual drive file is excluded from TM.

It seems that "problem" was caused by Postbox 3 e-mail database. I have to exclude it and|or find better mail client...
