TidBITS:

We think of “the cloud” as an amorphous space without limits. That may be true in the aggregate, but each of our personal cloud storage accounts has limits, and in comparison to the terabyte-sized drives in our Macs, our cloud accounts are often quite small. Nevertheless, you can usually go for years without bumping into their limits. I certainly did.

But when you do run out of space, it can be a major problem, since files may stop syncing, email could get rejected, and all sorts of other havoc could ensue. I recently hit this problem with iCloud, Dropbox, and Google.

As the tech guy for our family of 12 macOS and iOS connected devices, I’m the one charged with managing all the storage, backup, and maintenance details. What a PITA.
