Thanks. I'm doing some tests on my lab env where I deleted from aws about 12GB of an old backup station but storage account still count the whole amount before deletion.
I started the repo sync last wednesday 06/09 but when I open backup plan on rmm menu I still get repository sync in progress message. My only concern is that even local backups got stuck. Total storage on AWS before deletion was about 40GB. This is just a lab env though. Thank you for your quickly response.
