I updated to 6.0.1 from 5.18 last month, Sep 21 to be exact. At that time only 40% of the available drive space was used. Today I noticed that 80% was used. Through looking at the stats log, I can see each time weekly full backup is run, it eats about 15%. This is really different from what happened with version 5.
Will it keep doing this? I forsee running out of drive space really soon.
