I've got a stable remote installation on a VPS, with a handfull of apps. When I set it up, some time ago, I provisioned it with 75 GB of space, which seemed quite sufficient. Since then, I've added a couple of apps, but also deleted a few, and for a long while it was pretty stable at around 50 GB. In the last few weeks, the used space has risen a great deal, even though there's no obvious culprit (I'm not storing photos or any media for that matter, no new apps, etc.). I'm confused on what is taking up all the space.
My question is, how best to diagnose? Are there any apps or utilities that would show me which apps are using up the storage space?
Sorry if this is a simple question, my Linux commandline skills are not great I have to admit.
Thanks for the the help.
