Hello everyone I am not pretty sure if this is the right section, having a problem with time machine (software?) on a time capsule (hardware?) Anyway: I have a macbook air 13' (early 2015) running Mac OS High Sierra 10.13.4, and a Time Capsule A1409. The time capsule is not full by far, it has actually a Terabyte of free space out of 2. I had noted, in the past, that backups of dates that I tought I should have had were greyed-out, as if they were too old (the hard drive has never been far from full in the past, either) but I wasn't sure and I still not am, so it is a moot point now. What seems weird now, and the reason why I'm writing, is that Time Machine is performing a "cleaning up". Why is that, having so much free space? Is it compressing old files maybe, or deleting them? And if it is deleting, why? I could not find any option to limit the space dedicated to time machine, so I have always assumed that this kind of operation should have been performed when there was not space enough, which is not the case. Can you help me to figure this out? Thank you in advance for any help!
