time machine uses snapshots, which might take your disk space away if you do not know it. just for anybody wondering why they do not have any disk space left of

  The disk space used for snapshots is automatically re-claimed by the OS when it's needed by the user. The trade off is near-instant backup images. And while MacOS sometimes has issues expediently clearing space the was previously used for snapshots, tools like DaisyDisk and others can force its hand if you need. Bottom line, you don't lose available disk space by using Time Machine.

    That’s the theory, and it works like that on my MBP. But for some reason on my old iMac, snapshots used to just accumulate and every so often things start crashing because there was no space left, causing all sorts of issues. Sometimes the OS couldn’t boot because of that, it really was a pain. And yes, you can nuke snapshots preemptively, but often the first visible sign was Mail having corruption issues because it’s database was borked, at which point it was too late.
